    "A second aliquot of the preserved environmental field sample used to prepare the LFSM which is fortified, extracted and analyzed identically. The LFSMD is used instead of the Field Duplicates to access method precision and accuracy when the occurrence of target analytes is low. {OW/TSC}",
    "(radiochemistry) A third aliquot of a field sample that has the same quantity of radionuclide(s) added to it as the LFSM. The LFSMD is prepared and analyzed and results calculated exactly like the LFSM. It is used in place of the DUP to assess preparation batch precision when non-detects are frequent. {OW/TSC}"
