Selecting and Calibrating Compounds
Each compound you select will have pre-programmed analysis information stored in
the library. If you have selected compounds that are all run on the same column then
you need to run one analysis to calibrate your instrument.
If you selected compounds that must be separated on two columns, then you will
need to perform two runs in order to calibrate your instrument. During calibration,
you will select one column at time. Once the first column has been calibrated you
will select and calibrate the second column. When calibration is complete you can
enable both columns. When you are performing a sample analysis, you will need to
perform two runs, one on each column, in order to complete your analysis.
If your selected compounds require all three columns for separation, you will need
to complete three runs to calibrate the instrument. As with two columns, each
column will be calibrated separately. When calibration is complete you can enable
all three columns. When you are performing a sample analysis, you will need to
perform three runs, one on each column, in order to complete your analysis.
During calibration, Explorer will look for all compounds listed in the library. You
must obtain calibration gas containing all the compounds listed in the library. If
you are using more than one column/detector pair, you must obtain calibration gas
for each one.
NOTE: To obtain the most accurate identification and quantitation of the compounds,
ensure all compounds listed in the library are contained in the calibration gas.
