Performance Validation and Calibration Tab
The Performance Validation and Calibration tab is used to setup the information used for
calibration of both retention time and mass. The following image shows the performance validation
screen.
Following is a description of each of the columns in the top portion of the form.
•
Compound Name - This column is used for the names of the standards that will be used
for the calibration and validation of the instrument performance.
•
Retention Index
- This column contains the retention index values from the NIST
database. A description of retention indexes and how they are used is provided in the
Retention Time Calibration section of this manual.
• Retention Time - These values represent the time that the compound is expected to elute
from the instrument. If the Gas Chromatography method is changed then it is necessary
to run the standard mix and adjust the retention times in the Performance Validation
table.
•
Retention Minimum and Retention Maximum - These values are used to set a window
of time where the automatic calibration routines would expect the compound listed in the
table to elute.
• Retention Calibration - If the compound is to be used by the auto calibration routine to
calculate the retention indexes of unknown compounds this box must have a checkmark.
The compounds where the box is left unchecked may still be used for mass calibration
and/or performance validation.
Mass Item Table
The Mass Item table displays the selected masses for a specific compound as seen in the image
below.
