Performance Validation . 179
•
Min (Minimum) - In the compound bromoform the lowest index or bin number in which
the 174.908 mass can be detected is 1025.
• Max (Maximum) - In the compound bromoform the highest index or bin number in which
the 174.908 mass can be detected is 1220.
• Peak - A peak number can be specified to improve the accuracy of the calibration. For
example bromoform has a group of masses at 171, 173, and 174. Since the last peak in a
group is less susceptible to trap overloading effects the mass 174 would be used for
calibration. In this case mass 174 is peak number 3 of the group so a value of 3 would be
entered as the
Peak
number.
•
Total
- The total peak count specifies the number of mass peaks expected in a group of
peaks. In the case of bromoform there are 3 peaks so the Total peak count would be 3.
• Enabled - By placing a checkmark in this column the auto calibration routine is set to use
the specified mass. Leaving the box unchecked allows the information in the table to be left
alone but it will not be used for calibration.
Tests Section
The Tests section of the Performance Validation and Calibration tab can be accessed by clicking the
unlock icon on the mini toolbar and entering the password. See the icon description for Unlock
Performance Validation Tests in the mini toolbar at the beginning of this section for instructions
on how to use the unlock feature.
This section sets up the Tests that are performed to verify that the instrument is working correctly.
These are advanced functions and should only be modified by those trained to know how they work.
If there are questions about how to use the Tests section contact a PerkinElmer Service
Representative for help.
