Installation
4 Diablo 5000B Real-Time Gas Analyzer Getting Started Manual
Verify the MassHunter GC/MS Installation
Before attempting to acquire data from a 5977 MSD with the MS Sensor Software, you should verify
that the MassHunter GC/MS data system is configured correctly by performing a standard autotune.
MS Sensor Software
Before installing the Real-Time Gas Analyzer MS Sensor software, read the document “readme.txt”
in the root directory of the MS Sensor distribution USB flash drive. This document contains
installation and usage information that may not be included in the software manual or help file.
The MS Sensor Software Reference Manual is also provided on the USB flash drive. The reference
manual provides more detailed information on how to use the MS Sensor software than is included
in this Getting Started Manual.
To begin installation, run the installation program located in the root directory of the MS Sensor
software distribution USB flash drive. Follow the on-screen instructions.
Software Requirements
The MS Sensor 4.0 software is compatible with Windows 7 SP1, Windows 8/8.1, and Windows 10.
The .NET Framework 4.5.2 must be installed before trying to run MS Sensor 4.0. The .NET
Framework will be installed automatically, if necessary, when you install the software from the

Diablo 5000B Real-Time Gas Analyzer Getting Started Manual 7
Theory of Operation
Sampling Interface
The sampling interface for the Real-Time Gas Analyzer (RTGA) is shown in Figure 1.
Figure 1: The 5000B RTGA sampling interface.
The standard sampling interface consists of a sampling tee and a sampling cross. Sample input
tubing is connected to the top of the sampling tee. One branch of the tee is connected to the
sampling cross through a sample orifice, while the other is a vent line for excess sample. Since only
a small fraction of the sample input will flow through the sample orifice into the sampling cross, the
bulk of the sample can be routed back into the process or vented.
A fixed orifice (30 µm i.d.) limits the amount of sample that is drawn. The first orifice (the sample
orifice) is in between the sampling tee and the sampling cross. One branch of the cross connects to
the large “bypass” vacuum pump (Pfeifer DUO-10M, Edwards RV12, or Edwards nXDS-10i). This
pump reduces the pressure in the cross and pulls the majority of the sampled stream out to waste.
A second leg on the cross allows a precision pressure transducer to read the cross pressure. This
signal can be used to adjust the data for changes in sample pressure.

8 Diablo 5000B Real-Time Gas Analyzer Getting Started Manual
The final branch contains a second orifice (the high vacuum orifice) that further limits the amount of
sample reaching the mass spectrometer and allows the mass spectrometer to maintain the
necessary high vacuum (typically 1x10-6 Torr). The default orifice diameter is 50 µm for this stage.
Flow then passes through a vacuum isolation valve that is useful for troubleshooting and
maintenance. The outlet of the isolation valve connects to the mass spectrometer interface and
directs the sampled stream to the ionization region in the mass spectrometer.
The two orifices and the large vacuum pump allow the high-vacuum mass spectrometer to sample a
gaseous input directly with minimal dwell time. A thermal jacket envelopes the sampling tee and the
cross to maintain the desired sample temperature until high vacuum is encountered. The Watlow
EZ-Zone temperature controller regulates this temperature to the user-selected set point.
If excess sample is to be vented, it is recommended that some length of tubing be attached to the
outlet of the sample tee to limit back diffusion of air into the cross.
Additional Interface Options
Please contact Diablo Analytical for additional sample interface options and their suitability for your
application. These include:
Fast-response Interface: a low-volume tee configuration that provides T90 response times
of < 3 seconds.
Low-flow Direct Interface: A direct interface designed for very low flow rates (typically <= 4
mL/min, determined by the sample pressure and orifice diameter).
Vacuum Sampling Interface: A direct interface that is designed for samples at a slight
vacuum.

Diablo 5000B Real-Time Gas Analyzer Getting Started Manual 9
Setting up the Hardware
Connecting sample lines
Caution:
Particulates and condensed liquids or droplets in the sample stream can
plug the 30-μm sample orifice, which will then need to be replaced. It is the
responsibility of the user to ensure that their sampling system is designed
to eliminate particulate and liquid prior to the sample gas stream reaching
the RTGA sampling tee.
The sample input and output connections are standard 1/16-inch Swagelok fittings. By using 1/16-
inch tubing, the dwell time of the sample line can be minimized without introducing a large pressure
drop. The sample input is connected to the top of the interface and the vent or process return is
connected to the bottom of the interface. To make a new fitting connection, make sure the tube is
fully inserted into the fitting body. Finger-tighten the fitting and then tighten ¾ of a turn with a 5/16-
inch wrench on the compression nut and a 5/16-inch wrench on the adapter body.
Figure 2: A photograph of the RTGA interface with the sampling tee identified.
If necessary, user-supplied fittings can be used to adapt process lines to the 1/16 inch required for
the interface. Heating the sample lines is the responsibility of the user.

Changing Orifice Disks
The RTGA uses two laser-drilled orifice disks to provide pressure reduction in the sampling
interface. The orifice disks that are supplied with the RTGA are listed in Table 1. Note that orifice
disks with other diameters are available for special applications.
Table 1: Orifice disks included with the 5000B RTGA.
*The default orifice configuration Installed in the interface at the factory.
Note: The 350-um high-vacuum orifice is not compatible with all applications. In particular, it is not
compatible applications requiring hydrogen or helium tuning.
Important:
Due to the nature of the seal produced by the VCR fitting, the orifice
disks cannot be reused. Replacement orifice disks can be purchased
from Diablo Analytical.
Figure 3: A photograph of the RTGA interface with the VCR fittings containing the sample and
high-vacuum orifice disks identified.
The standard factory orifice configuration is applicable to a broad range of applications. However,
either orifice disk can be easily replaced using the following procedure.
1. Close the isolation valve to the MSD.

2. Note the current interface pressure, and then unplug the power cord to the MKS PDR 2000
pressure controller.
3. Turn off the bypass sampling pump.
4. Loosen the VCR fitting that contains the orifice disk that you want to change. The orifice
disk is used as the seal in the VCR fitting. You will need two open-end wrenches: 3/4" and
5/8". Once you have unscrewed and separated the two nuts, you can pull them away from
each other and expose the orifice disc, which will be sandwiched between the two ends of
the fittings.
5. Remove the old orifice from between the fittings. It is possible you may have to loosen the
screw that attaches the interface bracket to the side of the MSD in order to separate the two
fittings far enough for the high-vacuum orifice to be removed.
6. Insert the new orifice disk in between the two fittings - use gloves to handle the orifice so
that you don't get fingerprints on the surface. This step can be a little tricky, and it
sometimes helps to place the orifice inside the large hex nut first, and the slide it over the
mating fitting.
7. Re-tighten the two nuts - you should hold the large nut stationary while tightening the small
nut. You can use the small hole drilled in the side of the large nut to confirm that the orifice
is in place and didn't drop out. Don't over tighten the VCR fittings - tighten it 1/8 turn past
finger tight.
8. If you loosened the interface bracket screw, re-tighten it.
9. Turn the bypass pump back on.
10. Plug the power cord back into the pressure controller and wait for the reading to stabilize.
Make sure that the interface returns to a similar vacuum pressure as before.
11. Open the isolation valve and perform an autotune and check for leaks.
Temperature controller operation and maintenance
The 5000B RTGA is shipped with a custom temperature controller console using a Watlow EZ-Zone
Controller.
Caution:
The maximum temperature for the interface is 200 °C. Do not enter values
higher than this into the controller. It is possible damage the heater
blanket and/or the MSD electronics if you use interface temperatures
higher than 200 °C!

Setting up the Hardware

Watlow EZ-Zone Controller
Figure 4: The front panel of the Watlow EZ-Zone Temperature Controller.
Changing the interface temperature
Simply press the gray up/down arrows on the right side of the temperature controller to adjust the
interface temperature set point. The upper numeric display shows the actual interface temperature,
while the lower numeric display shows the current set point.
Setting the Temperature Display Units
Note: The temperature controller is set to units of ºC at the factory.
Use the following procedure to set the units of the displayed temperature (ºC or ºF). Refer to Figure
4. 1. Press and hold both of the gray up/down arrow buttons for approximately 6 seconds until
the controller shows “A1” in the top display, and “SEt” in the bottom display. Note that you
will have to continue to hold the buttons after “oPEr” appears in the lower display.
2. Press the down arrow key until the top display reads “9LbL” (for global). The bottom
display should still read “SEt”
3. Press the green advance button until “C_F” is in the bottom display.
4. Press the gray up arrow key until the desired temperature units are shown in the top
display (“C” or “F”).
5. Press the gray infinity key (“∞”) until you reach the “home” display with the actual
temperature in the top display and the set point in the lower display.
Auto-tuning the controller
Note: The temperature controller is auto-tuned at the factory at a temperature of 120 ºC.
If the actual temperature does not stabilize at the set point or significantly overshoots or
undershoots the set point, it may be necessary to “tune” the controller using the autotune function.
Please refer to Figure 4.

Setting up the Hardware
Diablo 5000B Real-Time Gas Analyzer Getting Started Manual 13
1. Start with the temperature controller off and the interface and heater blanket cold. In
addition, it is important to make sure that the heater blanket is tightly secured and in good
contact with the RTGA interface.
2. Turn on the temperature controller and press the up/down arrow buttons to select the
desired interface temperature set point.
3. Press the green advance button until the bottom display reads “AUt 1”.
4. Press the up arrow button until the top display reads “Yes” then press the infinity button to
return to the temperature display.
5. The unit should begin autotuning. The upper display will flash between “tUn 1” and the
actual temperature until the autotune is complete.
Caution:
During autotuning, the controller will cycle the temperature around a
value of 90% of the current temperature set point. Consequently, you
should be careful not to tune at a set point that results in the temperature
cycling above 200 °C.
Pressure sensor operation and maintenance
To connect the pressure sensor to the cross
Note: This procedure is normally performed at the factory during assembly of the interface.
The pressure sensor is connected to the sampling cross with standard VCR4 fittings. To install a
new pressure sensor, loosen the cap fitting with a 5/8- and 3/4-inch or adjustable wrenches. Use
the lint-free gloves included with the MSD ship kit to handle the VCR4 gasket. Carefully place the
gasket on top of the cross fitting and place the pressure sensor on top of the gasket. This is best
done if the female fitting on the pressure sensor is slid back to allow the sealing surfaces to meet.
Finger-tighten the male and female nut assemblies. Using the wrenches, tighten the fittings an
additional 1/8 of a turn.
To connect the pressure sensor controller to the PC
Two cables are included with the MKS PDR 2000 pressure sensor controller. One (part no.
CB628S-3-10) is for connecting the sensor to the controller while the other (part no. CBPDR-1-10)
is for connecting the controller to the PC. An appropriate power cord is also included for the sensor
controller.
To configure the pressure sensor controller:
The controller has no On/Off switch so, once it is plugged in, the LED display will light and begin to
flash. To obtain accurate readings, the PDR 2000 Controller needs to be configured for the sensor
in terms of units, full scale, and zero.
1 To begin configuration, press the [Select] button on the controller. The display will flash OFF
and the LED indicator will be on SetPt1 Hi.

Setting up the Hardware
14 Diablo 5000B Real-Time Gas Analyzer Getting Started Manual
2 Press [Select] four times so that Units is indicated. Use the [Raise] and [Lower] buttons to
scroll through the options until Torr is shown. Press [Select] to choose Torr; the controller
will advance to the Calibrate option.
3 Press [Select] again to move to the Full Scale option. Make sure that the controller is set to
the pressure sensor channel, CH1 or CH2. If you are using a single-channel cable to
connect the pressure sensor to the controller, then select CH 1. If you are using a dual-
channel cable, then select the channel that is identified in the label on the cable that is
connected to the sensor. Use [Raise] and [Lower] to set the full scale value to that of the
sensor. For the sensor supplied with the RTGA interface, this value is typically 2 torr.
However, you should confirm this by referring to the label printed on the side of the pressure
sensor.
Figure 5: The MKS PDR2000 pressure controller.
The controller is now configured and ready to be zeroed.
To zero the pressure sensor:
Note: The pressure transducer is zeroed at the factory. You should only re-zero the sensor if you
are certain that the calibration has drifted.
Important: Do not zero the pressure sensor if there is a leak anywhere in the interface assembly.
To check the current zero setting, make sure that the roughing pump for the interface is on. Close
the isolation valve to the mass spectrometer and plug the sample input and output branches on the
sampling tee. Allow the roughing pump to run for at least 15 minutes. The pressure should stabilize
near 0 Torr.
Important: The pressure should have been powered and heating for at least 4 hours before
attempting to zero the signal.
The pressure sensor can be zeroed in two places. A zero adjustment is located on top of the
transducer itself and can be turned to zero the pressure reading with a small flat-blade screwdriver
(MKS 728A sensor) or by pressing a recessed zero button (MKS AA02A sensor). Zeroing can also
be done on the controller front panel. Make sure that the channel selection is on the pressure
sensor to be zeroed (typically CH 1). Press the [Select] button until the Zero LED is lit. Using the
[Raise] and [Lower] buttons, adjust the readout to 0.000 torr.
If the sensor still cannot be zeroed, please refer to the MKS manual included with your system.
