10.1.7. SUMMARY OF QUALITY ASSURANCE CHECKS
The following items should be checked on a regularly scheduled basis to assure high
quality data from the T100. Refer to Table 10-3 for a summary of activities. Also the
QA Handbook should be checked for specific procedures.

10.2. LEVEL 1 CALIBRATIONS VERSUS LEVEL 2 CHECKS
Essential to quality assurance are scheduled checks for verifying the operational status
of the monitoring system. The operator should visit the site at least once each week. It is
recommended Level 1 zero and span check conducted on the analyzer every two weeks.
Level 2 zero and span checks should be conducted at a frequency desired by the user.
Definitions of these terms are given in Table 10-4.

recommended Level 1 zero and span check conducted on the analyzer every two weeks.
Level 2 zero and span checks should be conducted at a frequency desired by the user.
Definitions of these terms are given in Table 10-4.
In addition, an independent precision check between 0.08 and 0.10 ppm must be carried
out at least once every two weeks. Table 10-3 summarizes the quality assurance
activities for routine operations. A discussion of each activity appears in the following
sections.

To provide for documentation and accountability of activities, a checklist should be
compiled and then filled out by the field operator as each activity is completed.
