Section: V1M4, Section 1.6.3
Section 1.6.2 clearly indicates that an initial DOC is required for all analytes measured under a method. The language in section 1.6.3 for continuing DOC is not as specific. Must all analytes reported under a method/technology be included in the continuing DOC, or can a representative group of analytes be chosen and indicated within laboratory SOPs?
TNI FINAL RESPONSE:
Section 1.6.2 (IDOC) is specific to each matrix-method-analyte combination.
Section 1.6.3 (ODOC) does not state that it is specific to each matrix-method-analyte combination. The standard allows the use of an LCS or PT samples which are not required to contain every compound according to the standard as acceptable forms of ODOC.
Note that Section 1.2 states that 'Additional QC requirements that are either specified by method, regulation or project shall be met by laboratories.' In such a case, all analytes accredited under a method/technology may need to be included in the continuing DOC.
