To Verify System Performance
Materials needed
• 1 pg/µL (0.001 ppm) OFN sample (5188-5348)
Verify the tune performance
1 Verify that the system has been pumping down for at least 60 minutes.
2 Set the GC oven temperature to 150 °C and the column flow to 1.0 mL/min.
3 In the Instrument Control view, select Checkout Tune from the Checkout menu.
The software will perform an autotune and print the report.
4 When the autotune has completed, save the method and then select
Evaluate Tune from the Checkout menu.
The software will evaluate the last autotune and print a System
Verification – Tune report.
Verify the sensitivity performance
1 Set up to inject 1 µL of OFN, either with the ALS or manually.
2 In the Instrument Control view, select Sensitivity Check from the Checkout
menu. The system displays an Alert dialog reminder about resolving the
OFN_SN method and placing the OFN sample in vial 1 when an ALS is
configured.
3 If necessary resolve your hardware with this method and place the sample
in the vial 1 position.
4 Click OK to run the method.
When the method is completed, an evaluation report will be printed.
Verify that rms signal-to-noise ratio meets the published specification. Please
