Dangerous contaminants
Biohazards or radioactive materials and infectious agents:
Instruments, accessories, components or other associated materials may not be returned to
us or other accessory manufacturers if they are contaminated with biohazard or radioactive
materials, infectious agents, or any other materials and/or conditions that could constitute a
health or injury hazard to employees. Contact us if you have questions about decontamination
requirements.
Using liquid nitrogen
Some detectors must be cooled with liquid nitrogen before use. The following symbols remind
you to wear protective clothing when using liquid nitrogen.
Warning: Liquid nitrogen is extremely cold and therefore potentially hazardous. When
filling the detector dewar, be careful not to contact the liquid nitrogen with your skin. Wear
protective gloves and splash-proof goggles and follow standard laboratory safety practices.
Warning: To avoid hazardous equipment damage or contact with liquid nitrogen, make
sure any dewar or container you use to hold liquid nitrogen can do so safely without breaking.
Using corrosives and solvents
Caustic or corrosive agents:
Instrument components may be degraded by exposure to caustic or corrosive agents or their
vapors. Materials such as hydrochloric acid and hydrofluoric acid are particularly corrosive and
may accelerate the degradation of the metallic components in your instrument. Damage can
also occur if the concentration level of corrosive gasses in the air is excessively high due to
improper sampling techniques.
To maintain the instrument in safe working condition, do not use caustic agents, such as
acetone or chlorinated solvents, when cleaning or operating your instrument. Damage to the
instrument caused by the use of caustic agents is not covered by the warranty.
9

Volatile solvents:
You can use your instrument to analyze samples dissolved in solvents, but you must follow the
guidelines listed below. These measures will help prolong the life of your instrument and will
eliminate the possibility of spectral interference caused by volatile solvent vapors.
–—Use sealed sample holders.
–—Do not leave exposed solvent in the sample compartment for longer than necessary.
–—Do not leave the solvents near the instrument.
–—Be sure that your work space is properly ventilated.
Solvents containing halogenated hydrocarbons:
The pyrolysis of chlorinated solvents, perfluorochlorinated solvents, and other solvents by an
infrared source or by excessive heating caused by laser absorption may produce hydrochloric
acid (HCl), hydrofluoric acid (HF), phosgene (COCl2), or other hazardous compounds.
Warning: Materials such as hydrochloric acid, hydrofluoric acid and phosgene are highly
toxic. If you regularly use solvents containing halogenated hydrocarbons, your work area must
be properly ventilated, and your system must be purged while the solvents are in use.
Damage to your system due to pyrolysis of halogenated hydrocarbons and/or exposure to
other corrosive or caustic agents is not covered by the warranty.
Checking the power supply
Danger: Your instrument is powered by an external power supply that accepts a variety of
AC power sources and adjusts automatically to maintain a consistent VDC output. To avoid
injury, only a qualified person using the appropriate measuring device should check the line
voltage, current and frequency.
10

Operation
Turning the power on and off
To turn the system power on or off, press the power switch on the power supply.
Aligning your instrument
Your instrument can be aligned automatically using OMNIC Picta. For information about
aligning your instrument, please refer to the software help for OMNIC Picta.
Positioning a manual stage
Note: Use the software to adjust the focus with a manual stage.
11

Positioning a motorized stage
Caution: The instrument may contain an automated stage that is controlled by the
software. There are several places on and around the stage where a person or object could be
pinched by moving parts. When operating the system, keep hands and fingers away from the
stage area except to position the sample or change accessories. Remove your hands from the
system when operating the software and when the stage is moving.
The joystick moves the motorized stage left and right along the X-axis or forward and back
along the Y-axis.
Note: You must use OMNIC Picta to adjust the focus. OMNIC Picta also has a virtual joystick
you can use to move the motorized stage along the X-axis and Y-axis. For more information
about these features, see the OMNIC Picta software help, which you can open by clicking the
Help button in OMNIC Picta.
Setting the purge gas controls
You must connect a source of purge gas (dry air or nitrogen) to purge your instrument of
moisture and other environmental contaminants. For best results the purge gas should be
dried to a dew point of -70 degrees C (-94 degrees F) or below. Use the following instructions
to set the purge gas controls.
Note: Your instrument has two purge lines that will need to be set separately.
Notice: We recommend that you maintain the seal and desiccate and/or purge your
modulator compartment at all times. Equipment damage due to failure to maintain seal and
desiccation and/or purge is not covered under the warranty. If you have questions about this
requirement, please contact us.
Warning: Never use a flammable gas to purge your instrument. The purge gas must be
free of moisture, oil, carbon dioxide and other reactive or infrared-absorbing materials. To
prevent laser damage, use only dried air or nitrogen to purge your instrument.
12

1.—Open the shutoff valve.
2.—Adjust the pressure regulator for the interferometer purge line until the gauge indicates
that the pressure is 20 psig. Adjust the pressure regulator for the instrument purge line
until the gauge indicates that the pressure is 15 psig.
Notice: Flow rates greater than 10 scfh can cause vibration that can affect data quality. We
recommend keeping the flow rates for both purge lines at approximately 10 scfh.
3.—Set the flowmeters to 10 scfh.
13

Cooling a detector
Use this procedure if you have a detector that must be cooled with liquid nitrogen before you
can collect data.
Time needed: 40 minutes or less
Tools needed: Protective clothing and eyewear
A small plastic laboratory funnel
A one-liter, metal vacuum bottle
Liquid nitrogen
Note: Your instrument may have one or two detector dewars. The procedure below shows an
instrument with two dewars.
Note: A detector dewar should maintain its insulating vacuum for several years. If the
vacuum leaks, the insulation will lose effectiveness.
Note: Your detector, when cooled according to the following procedure, should remain cool
for approximately 18 hours.
Warning: Liquid nitrogen is extremely cold and can be hazardous. When you use liquid
nitrogen, always follow standard laboratory safety practices, and make sure your dewar is
made to use with liquid nitrogen. Wear protective clothing and eyewear, and avoid letting
liquid nitrogen come into contact with your skin.
1.—Open the detector dewar cover and remove the plastic stopper from the dewar.
Warning: Make sure you pour the liquid nitrogen slowly when you fill the vacuum bottle or
the detector dewar. Pouring too quickly can cause liquid nitrogen to spray out. Wear protective
clothing and eyewear, and follow standard laboratory safety practices to prevent injury.
2.—Fill the metal vacuum bottle with liquid nitrogen.
Notice: Do not spill liquid nitrogen on or near the detector window. If the window’s O-ring
seal is cooled very rapidly, the dewar may lose its vacuum and expose the detector element to
damaging atmospheric pressure.
14

3.—Insert the funnel into the detector dewar, and pour the liquid nitrogen slowly into the
funnel. (A small amount of liquid nitrogen typically spills out of the funnel. This will not
harm your instrument.)
Fill the funnel and then let it drain completely two or three times. Wait until the vapor
plume disappears and then repeat until the dewar is filled.
4.—Remove the funnel.
5.—Wait until the vapor plume disappears, and then replace the plastic stopper and close the
dewar cover.
6.—Wait 20 minutes, and then repeat the preceding steps to make sure the dewar is
completely filled.
7.—If your instrument has two dewars, you can repeat this procedure (if needed) for the
second dewar.
Installing a slide-on ATR attachment
Note: For information about collecting data with a slide-on ATR attachment installed, please
refer to the software help system.
15

Using the purge collar ring
Collecting data with the instrument
You must use OMNIC Picta to collect data. OMNIC Picta can be started by using the OMNIC
Picta shortcut on your system desktop. For additional information, please see the OMNIC Picta
help, which you can open with the Help button in OMNIC Picta.
16

Service
Static electricity precautions
Critical components in your instrument can be permanently damaged by static electricity. To
help prevent such damage, follow these recommendations:
Notice: Before you disconnect the power supply, always discharge any static electricity you
may have accumulated by touching the metal base of your instrument.
Notice: Do not touch any printed circuit board in your instrument (such as the circuit board
on the detector).
Notice: Do not remove replacement components from their protective packaging until you
are ready to install that component in your instrument.
Installing a purge kit
Purging your instrument protects the internal components from moisture and other
environmental contaminants by maintaining an internal atmosphere of dry air or nitrogen. If
your instrument is not already equipped to purge, you must install a purge kit. To install a
purge kit, use the following procedure.
Notice: We recommend that you maintain the seal and desiccate and/or purge your
modulator compartment at all times. Equipment damage due to failure to maintain seal and
desiccation and/or purge is not covered under the warranty. If you have questions about this
requirement, please contact us.
Time needed: 30 minutes or less
Tools needed: A 3/4 inch open-ended wrench
An 11/16 inch open-ended wrench
A shutoff valve (with a 1/4 inch male or 3/8 inch female fitting)
Pipe tape
Note: For best results the purge gas should be dried to a dew point of -70 degrees C
(-94 degrees F) or below.
17

Note: There are two purge connectors on your instrument (one for the instrument and one
for the interferometer), so you will have to install two purge lines, which are included with
your instrument.
Warning: Never use a flammable gas to purge your instrument. The purge gas must be
free of moisture, oil, carbon dioxide and other reactive or infrared-absorbing materials. To
prevent laser damage, use only dried air or nitrogen to purge your instrument.
1.—Install a shutoff valve and either a 1/4 inch male fitting or a 3/8 inch female fitting on the
purge gas source. (Choose a shutoff valve and fittings that are appropriate for the purge
gas source.)
2.—If you used a 1/4 inch male fitting, proceed to the next step.
If you used a 3/8 inch female fitting on the purge gas source, install the 3/8 inch to 1/4
inch reducing nipple that was included with your purge kit. Wrap the reducing nipple with
Teflon pipe tape before you install it, and use an 11/16 inch open-ended wrench to tighten
the connection.
3.—Wrap the reducing nipple or the 1/4 inch male fitting with Teflon pipe tape, and then
install the pressure coupling. Use a 3/4 inch open-ended wrench to tighten the connection.
