DQM Check for Radio Chemistry Tracer Recovery

The DQM Check for Radio Chemistry Tracer Recovery will qualify results if tracer sample recoveries fall outside Quality Control (QC)  limits. (Note that DT_RESULT_QC must be populated for this check to function).

 

Check name is EarthSoft.DQM.RadChemTracerRecovery = Radiochemistry Tracer Recovery.

 

This check uses the reportable_result, result_type_code and test_batch_type parameters from Global Parameters. There are two other parameters:

Result_type_code_tracer – Defaults to TRA.

SecondTracer – If “Y”, then a second tracer must fail the test before results are qualified. This parameter depends on the value entered in the ANALYTIC_METHOD column. Defaults to “N” if no parameter entered.

 

Notes:

The default value is used if there is no record in RT_DQM_CHECK_PARAM for an input parameter.

The default value is used if the PARAM_VALUE is NULL for this parameter in RT_DQM_CHECK_PARAM.

 

There are six rules:

1.REC > UCL = DT_RESULT_QC.QC_SPIKE_RECOVERY > DT_RESULT_QC.QC_SPIKE_UCL.

2.ASSO DETECTS OF REC > UCL.

3.ASSO NON-DETECTS OF REC > UCL.

4.REC < LCL = DT_RESULT_QC.QC_SPIKE_RECOVERY < DT_RESULT_QC.QC_SPIKE_LCL.

5.ASSO DETECTS OF REC < LOW_CUTOFF.

6.ASSO NON-DETECTS OF REC < LOW_CUTOFF.

 

For tracer results:

Associated results are found using DT_TEST.TEST_ID.

Different qualifiers may be specified for those associated results with a detected concentration, and for those without (i.e., non-detect).
