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 three Global Parameters:
1.reportable_result – DT_RESULT.REPORTABLE_RESULT values to include in DQM datasets
2.result_type_code – DT_RESULT.RESULT_TYPE_CODE to include in DQM datasets
3.test_type_batch – AT_TEST_BATCH_ASSIGN.TEST_BATCH_TYPE to include in DQM dataset
Two parameters are available for this check. None of these parameters allow for input of analyte-specific PARAM_VALUEs. The SecondTracer parameter requires input of an analytical method.
1.Result_type_code_tracer – Defaults to "TRA".
2.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: Default parameter values listed above refer to the value provided in the DQM Starter QAPP.xlsx. |
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).
In the Errors tab of the DQM Event Review Form, these errors may be listed:
•"One of the required rules for this check is not present in the RT_DQM_RULE table."
If you receive this error, the QAPP can be updated following the How to Update Existing QAPPs documentation page.
•"Tracer LCL/UCL IS Not Numeric."
If you receive this error, the check will be skipped.
•"Spike Duplicate Recovery data missing from DT_RESULT_QC for either {0} or {1} and {2}."
If you receive this error, the check will be skipped.
