Volatile Organic Data Review - Continuing Calibration
2.5
Do the RRFs of the SPCCs (listed in Table 1.0) in the 12-
hour standard meet the initial SPCC criteria (Table 1.0)
for each 12-hour shift?
Note: RRFs in the ICV or CCV should be compared to initial
calibration RFs.
Action: Corrective action should be taken to solve the source of
the problem. If the source of the problem could not be determined,
a new 5-point calibration should have been generated. List all
sample analyses that were affected. Call the laboratory for
explanation or re-submission. If continuing calibration data are not
available, flag all associated sample data as “R.”
2.6
The system should be re-calibrated if any of the SPCCs
fail to meet minimum RRF or maximum %D criteria.
Note: For data review purposes, all compounds must be
considered for qualification when the %D exceeds the 50%
criterion.
Action: Ask the laboratory for an explanation. If analyses were
performed without corrective action, initially “R” all data. Upon
explanation, the Tier II Data Validator may use best professional
judgement to qualify positive sample results as “J-.”
2.7
Do the RRFs of the SPCCs (Table 1.0) in any batch
specific CCV standard (or 12-hour standard) meet the
initial SPCC criteria (Table 1.0)?
Note: RRFs in the CCV are compared to initial 12-hour
calibration RFs.
Action: Corrective action should be taken to solve the source of
the problem. If the source of the problem could not be determined,
a new 5-point calibration should have been generated. List all
sample analyses that were affected. Call the laboratory for
explanation or re-submission. If continuing calibration data are not
available, flag all associated sample data as “R.”
2.8
Do any Calibration Check Compounds (CCCs) in the
CCV have a % Difference (%D) between the 12-hour
standard and the initial calibration which exceeds the +/-
25 % criteria?
Note: The lab may establish their own criteria (e.g., +/- 20%).
Action: Corrective action should be taken to solve the source of
the problem. If the source of the problem could not be determined,
a new 5-point calibration should have been generated. List all
sample analyses that were affected. Call the laboratory for
explanation or re-submission. If continuing calibration data are
not available, flag all associated sample data as “R.”
