• Sample analysis records pertaining to the PT sample, MDL study, and LLOQ study results submitted for the application to include sample preparation records (digestion, distillation, etc.), standard preparation records traceable to the certificates of analysis, quality control data, and all data system reports (where applicable) for the completed analyses demonstrating traceability.
• If a PT sample, MDL study, and LLOQ study are not required for the parameter, submit the most recent initial or multilevel calibration (ICAL) and calibration verification (performed within the last 12 months).

Organic

• Multilevel calibration (ICAL) and calibration verification records documenting that method acceptance criteria have been met for each analyte related to the PT sample study. Where applicable, the data must be submitted for both the primary and confirmatory techniques.

Also, include extraction records, standard preparation records traceable to the certificates of analysis, quality control data, all chromatograms and data system reports for the completed analyses.  The data must include all before and after manual integrations. Where applicable, the data must be submitted for both the primary and confirmatory techniques.
• Compiled initial demonstration of capability (IDOC) data results for each method and analyte including all information on the example form . Where applicable, the IDOC data must be submitted for both the primary and confirmatory techniques.
• Compiled MDL study performed within the last 12 months by analyte and method including all information on the example form along with the MDL sample chromatograms and data system reports demonstrating traceability. Where applicable, the MDLs must be submitted for both the primary and confirmatory techniques.
• Compiled LLOQ Study (SW-846 Methods only) for each instrument used to report data for each parameter/method.
