Inject the Test Sample
Use 1
µ
L of the Varian test sample for all detectors. In addition, if you are
using a PFPD, make a 1:20 dilution of the test sample in iso-octane. With the
READY light on at the GC and the appropriate volume of test sample in your
injection syringe, you are ready to make your injection. For automated
injection of samples, please refer to the 8200/SPME AutoSampler Operator’s
Manual, P/N 03-914692-00.
•
To inject your sample, insert the syringe needle into the injector inlet,
press the syringe barrel against the injector switch and depress it
completely, simultaneously pressing down the syringe plunger. Remove
the syringe from the injector immediately.
•
The RUN light comes on and stays on until the analysis ends. The run
may be stopped by pressing the STOP key.
•
Compare the resulting chromatogram with your known test
chromatogram.
•
If you are analyzing the Varian Test Sample on a Varian Test Column, you
may compare your resulting chromatogram with the appropriate test
chromatogram in the Detector section of the Operator’s Manual. The
retention times will be close to those shown in the manual. The peak
heights may be considerably different.
•
Failure to duplicate the results you expected may indicate an installation,
operation or instrument problem. This problem must be corrected before
proceeding.
