The DQM Check for Estimated Results checks for sample results between the method detection limit and the reporting limit or the quantitation limit.
Check name is EarthSoft.DQM.EstimatedResults = Estimated Results.
This check uses the reportable_result and result_type_code parameters from Global Parameters.
There is one other parameter:
1.estimated_detection_limit
a.defaults to "reporting_detection_limit"
b.can be changed to "quantitation limit"
There are two rules and they are:
1.MDL=<RESULT<RL (INORGANIC)
2.MDL=<RESULT<RL (ORGANIC)
Qualify a result IF:
•DETECT_FLAG = 'Y' and
•If estimated_detection_limit = "reporting_detection_limit" then
oMETHOD_DETECTION_LIMIT <= RESULT_NUMERIC <REPORTING_DETECTION_LIMIT
•Else if estimated_detection_limit = "quantitation_limit" then
oMETHOD_DETECTION_LIMIT <= RESULT_NUMERIC < QUANTITATION_LIMIT
An error is listed in the Errors tab of the DQM Qualification Report Form if:
•METHOD_DETECTION_LIMIT, REPORTING_DETECTION_LIMIT, QUANTITATION_LIMIT or RESULT_NUMERIC is NULL
•There is an error when DETECTION_LIMIT_UNIT is converted to RESULT_UNIT
