1. InfraCal 2 Overview
1.1. Introduction
The InfraCal 2 Analyzer is a filter based mid infrared analyzers with pre-selected filters for up to three
discrete wavelengths. The sample stage is also preset for either transmission or ATR (Attenuated Total
Reflection)
1.2. Basic measurement concept
The InfraCal 2 Analyzer makes use of the fact that most molecules absorb at specific infrared frequencies
that are characteristic of their structure. The amount of energy absorbed is proportional to the
concentration of the specific molecule. A calibration table converts the infrared absorbance into the
desired units of measure.
The InfraCal 2 touch screen display includes the capability for multiple calibrations, a wizard guide for
calibration, multiple level user database, multiple languages with user preference selection, high/low
alarm and control limits, and measurements stored in a history table for recall or export to a flash or
serial port.

1.3.1. Location
The InfraCal 2 Analyzer is designed for on-site measurements and is relatively insensitive to vibration
and ambient temperature changes. For more sensitive readings below 1 ppm, it is best to avoid dramatic
temperature changes such as direct sun or a location in the direct air flow of a heating or air conditioning
vent.
1.3.2. Power requirements
A standard 18 volt power supply is provided with the analyzer and an optional internal battery pack is
available at the time of purchase. The analyzer may be operated from any grounded A.C. outlet (line
power requirements: 100 - 250 VAC, 50-60 Hz, 0.5-0.3 amps). When operating, the InfraCal 2 Analyzer
uses 0.5 amps and up to 2.1 amps with the internal battery charging.
Note: Use of any other power supply than the one provided with the analyzer will void the instrument
warranty.
1.3.3. Warm up time
For normal operation, it is recommended that the instrument be allowed to warm up for 1 hour prior to
use. The InfraCal 2 Analyzer draws very little power and, if used daily, it can be left on at all times
(unless operated from the internal battery pack).
1.4. External ports
1.4.1. Communications ports
RS232 Port –DB-9F DCE connector for connection to host computer (DTE) with a straight through
cable.
USB Port –USB 2.0 mini B connector for connection to host computer
Ethernet Port –RJ45 connector-future option
1.4.2. External memory ports
USB 2.0 Type A connector –for standard USB memory devices
SD Card Port –secure data port-future option

1.5. Power on-off
Press the ON/OFF button to turn the instrument on. Press again to turn the instrument off. If the
instrument fails to turn off, press and hold the ON/OFF button until the instrument powers down
(about 5 seconds). No settings will be lost.
1.6. Touch screen interface description
The LCD is a resistance type touch screen. Commands are best activated with a resistance screen stylus, pencil
eraser or tip of the finger or fingernail. Do not use sharp objects. Damage to the LCD touchscreen by the use of
sharp objects is not covered by the InfraCal 2 warranty. While resistant to many chemicals, it is best to avoid
chemical contact on screen surface. Surface can be cleaned with a soft cloth and if necessary with some plastic
surface cleaner applied to the cloth.

Opens table for calibration points. Calibration data can be
entered directly into this table.
Press when last point is entered
Select “Curve” if calibration standards need to be tested for
absorbance values.
Zero the analyzer prior to collecting calibration data with the
appropriate zero for the analysis
Enter Calibration standard value using the keypad. It is best to go from the lowest
calibration value to the highest.
Introduce lowest standard and select “Run”. It is
suggested that each standard is run at least three times.
Re-introduce the standard and select run again. The absorbance
values for each run is shown on the left side of the display
Point: Displays the current number of the standard
being measured by the instrument starting at 1.
Value: Displays calibration standard value
Under “Value”are the results from repeated runs of
the calibration standard. If one value is significantly different from the other
values, it should not be used as part of the calibration curve. Tap on the
text/box to deselect and remove that run from the average calculation.
After a satisfactory number of measurements of a standard have been made, select
“Add”and the average absorbance will be entered into the table along with the
calibration standard value.
Repeat this sequence for each standard.
