InfraCal 2 ATR-SP Quick Start

Initial setup – Quick start

Factory calibrated analyzer

See Section 4.1.3 in the InfraCal 2 Operation Manual for details on the analysis screens.

1. Select “Analysis” and select the desired calibration.

2. To set the optional alarm limits, zero expiration, calibration expiration or other parameters in

the menu, select “Edit”, then “Next” to scroll through options menus. Select “Done” when

complete. Some options are not available to change in a factory calibration.

3. Select “Done” again to begin analysis.

4. Select “Zero” then select “Set Zero”

5. Clean ATR crystal by putting solvent in the trough and wipe in one direction and allow to dry

6. Select “Zero”. If reading is not zero, repeat cleaning the ATR crystal and select “Zero” again.

7. If reading is still not zero and ATR crystal is clean, select “Set Zero” and “Done”. See section 2.4

for zeroing details.

8. For measurements below 2 ppm solvent purity testing is necessary. It is recommended to check

solvent purity periodically for higher levels as well. See Section 2.4.1 below for Solvent Purity
Testing.

9. The InfraCal 2 is now ready for sample analysis. See Section 4 “Analyzing a Sample” in this

manual for details on sample preparation.

Note: If your analyzer has a cover for high level measurements with perchloroethylene, do NOT
close the cover with hexane measurements as the hexane will not evaporate and your reading will

include residual hexane.

Uncalibrated analyzer

See Section 4.1.3 in the InfraCal 2 Operation Manual for details on the analysis screens.

Calibration

1. Select “Analysis”, then “New”.

2. Name the analysis by selecting the text box. Enter precision. For levels high level calibrations it

should XXXXX. and for levels below 10 ppm it should be XXXX.X. Select desired units.

3. Select “Next” and set Run Countdown Timer (4 minutes is suggested) and Zero Countdown

Timer (4 minutes is suggested for low level readings). Select “Skip” to activate the option to skip

the timer during operation.

4. Set Measurement Time to 30 seconds. The zero and calibration expirations are optional.

5. To set the optional alarm limits, zero expiration, calibration expiration or other parameters in

the menu, select “Next” to scroll through options menus. Scroll though drop down box to see

complete list.

6. When table is displayed, select cell “Point 1” under “Absorbance” and enter “0”.

7. Select “Curve”.

8. With the appropriate standards covering the range of analysis, begin generating the calibration.

9. Begin with the lowest standard value. Select “Value” and enter the calibration standard value

using the keypad followed by “=”

10. Put the 60 microliters of the standard into sample holder and select “Run”. Repeat the standard

at least three times. The results will be shown on the left side of the screen. Select the results
that will be averaged for that standard value. If one of the results is significantly different, it
should not be included in the calibration. Tap the value to deselect.

11. When complete, select “Add” and the first calibration point will be added to the table.

12. Select “Value” for the next calibration standard and repeat steps 8-10 for the remaining

standards.

13. After the last standard, select “Back” to review the table. Adjustments can be made to the table

by tapping the appropriate text box and using the keypad.

14. If the calibration is complete, select “Done”. The calibration is now part of the Analysis table.

15. Select “Done” again to begin analysis. See Section 4 “Analyzing a Sample” for details on sample

preparation in the InfraCal ATR-SP Manual for Oil in Water.

16. Once the calibration is entered, it is recommended that the solvent purity is checked. See

Section 2.4.1 below for Solvent Purity Testing.

Note: If your analyzer has a cover for high level measurements with perchloroethylene, do NOT
close the cover with hexane measurements as the hexane will not evaporate and your reading will

include residual hexane.
