DQM Check for Radio Chemistry Estimated Results

The DQM Check for Radio Chemistry Estimated Results checks for radio chemistry sample results between the minimum detectable concentration and the decision level concentration.

 

Check name is EarthSoft.DQM.RadChemEstimatedResults = Radiochemistry Estimated results.

 

This check uses the REPORTABLE_RESULT and RESULT_TYPE_CODE parameters from Global Parameters.

 

There are two rules:

1.MDC < RESULT < 3*MDC.

2.MDC < RESULT < 3*TPU(1 sigma).

 

Qualify a result with the first rule if, in DT_RESULT:

MINIMUM_DETECTABLE_CONC < RESULT_NUMERIC < 3 x MINIMUM_DETECTABLE_CONC.

 

Qualify a result with the second rule if, in DT_RESULT:

MINIMUM_DETECTABLE_CONC < RESULT_NUMERIC < 3 x TPU(1 sigma),

where TPU(1 sigma) = RESULT_ERROR_DELTA if UNCERTAINTY = "1 sigma", or

where TPU(1 sigma) = RESULT_ERROR_DELTA / 1.96 if UNCERTAINTY = "2 sigma".

 

An error is listed in the Errors tab of the DQM Qualification Report form if:

MINIMUM_DETECTABLE_CONC, or RESULT_ERROR_DELTA is NOT NUMERIC.

UNCERTAINTY is not equal to "2 sigma" or "1 sigma".

 

This check only qualifies records where MINIMUM_DETECTABLE_CONC, RESULT_ERROR_DELTA, and UNCERTAINTY are not NULL.
