Understanding Your Agilent ChemStation 261

Verification and Diagnosis Views
Verification test results are saved in binary format to the default subdirectory:
c:\CHEM32\1\Verify, together with the method and data files. The Verify
subdirectory is at the same level as the sequence, methods and data
subdirectories. You can send the results to a printer or to a file. The test
results, including a combined verification test result, are rated as either pass
or fail.
The following verification test components are available:
Digital Electronics (Agilent 1100/1200 Series DAD only)
A test chromatogram is stored in the diode-array detector. This chromatogram
is sent to the ChemStation after it has gone through the same preprocessing
steps as normal raw data from the photodiodes. The resulting data are
compared to original result data stored in the ChemStation for this test
chromatogram. If there is a mismatch the test fails. This test ensures that the
DAD electronics which do the data preprocessing are still functioning
correctly. As a stored test chromatogram is used, the lamp or the diode array
are not part of this test. They can be checked with the “DAD Test Function” on
page 265.
Peak Integration
The data file is integrated again using the original method. The results are
compared to the original integration results stored in verification register. If
they do not match, the test fails.
Compound Quantification
The compounds in the data file are quantified again. The results are compared
to the original quantification results stored in the verification register. If they
do not match, the test fails.
Report Printing
The original report is printed again.
The following page shows an example of a successfully completed verification
test.
