Quality Control Sample

Acceptance Criteria

Corrective Action

Positive control

Produces expected result, positive result

Re-prep and reanalyze the entire analytical batch, once. If problem persists, locate and remedy the source of unexpected result, then re-prep samples and reanalyze with a new set of controls.

Negative control

Produces expected result, negative result

Re-prep and reanalyze the entire analytical batch, once. If problem persists, locate and remedy the source of unexpected result, then re-prep samples and reanalyze with a new set of controls.

Laboratory replicate sample

Sample results shall concur

Reanalyze sample and associated replicate sample once. If problem persists, re-prep samples and reanalyze.

Table 4

Quality Control Sample

Acceptance Criteria

Corrective Action

Method Blank Sample

Not to exceed LOQ

Reanalyze entire analytical batch once. If method blank is still greater than the LOQ for any analyte, locate the source of contamination then re-prep samples and reanalyze.

Laboratory Control Sample

RPD <=20%

Reanalyze the entire analytical batch, once. If problem persists, re-prep samples and reanalyze or re-run the initial calibration curve.

Duplicate Sample

RPD <=20%

Reanalyze sample and associated replicate sample once. If problem persists, re-prep samples and reanalyze.

Matrix Spike Sample/Matrix Spike Duplicate

RPD <=20%

Reanalyze sample and associated matrix spike sample once. If problem persists, re-prep samples and reanalyze.

CCV

RPD <=20% except for lowest point, which can be ±30%

Reanalyze all samples that followed the last CCV that met the acceptance criteria. If CCV still fails, re-run the initial calibration curve and all samples in the analytical sequence.
