Semi-Volatile Data Review - Continuing Calibration Verification
2.4
Do the RRFs of the SPCCs in the 12-hour standard
(CCV) meet the initial SPCC criteria (0.05) for each 12-
hour shift?
Note: The 12-hour standard (CCV) RRFs are compared to the
initial calibration.
Action: If the RRFs of the SPCCs do not meet the criteria,
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.”
2.5
Do any CCCs (Table 3) have a percent Difference (%D)
between the initial calibration RRFs and continuing
calibration (12-hour standard) RRF that exceeds the +/-
30% criteria?
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 an
explanation or a re-submission. If continuing calibration data are
not available, flag all associated sample data as “R.”
2.6
Were samples analyzed within 12 hours of either the
Continuing Calibration Verification (12-hour standard) or
the initial calibration?
Action: If samples were not analyzed within the 12-hour window,
all positive results should be regarded as “J.” If other criteria is
also outside of requirements, the Data Validator may qualify data
as “R.”
2.7
The Tier II Data Validator should evaluate relative
response factors (RRFs) for all the target compounds
and surrogates in any batch specific continuing
calibration verification. The RRFs in the CCV should be
greater than 0.05 and the %D between the batch CCV,
and the 12-hour standard should be less than 30%.
Note: A 12-hour standard is needed once per day, and a
continuing calibration verification is needed for each batch or
every 20 samples. The NFGs allow four compounds to have
less than 40% RRF while still considering the data acceptable.
Action: If the %D is greater than or equal to 30% and the RRF is
greater than 0.05, all positive results for these compounds should
be qualified as “J” and all non-detected compounds qualified using
the Data Validator’s professional judgement.
If the RRF is less than 0.05, qualify all positive results as “J” and
all undetected compounds as “R.”
