Measurement Of N-Methylcarbamoyloximes And N-Methylcarbamates In Water By Direct Aqueous Injection Hplc With Postcolumn Derivatization
3. DEFINITIONS
3.1Analysis Batch – A set of samples prepared and analyzed on the same instrument during a 24-hour period. An analysis batch begins with a Continuing Calibration Check (CCC) at or below the MRL. Subsequent CCCs are analyzed every 10 samples, should alternate between medium and high concentrations, and must end the analysis batch. An analysis batch is limited to 20 field samples. Laboratory Reagent Blanks (LRBs), Laboratory Fortified Sample Matrices (LFSMs), Laboratory Fortified Sample Matrix Duplicates (LFSMDs), Field Duplicates (FDs), and CCCs are not counted as samples. Required batch QC samples include: LRB, CCC, LFSM, and either a FD or a LFSMD.
If a sample(s) in an analytical batch needs to be reloaded for analysis within 48 hours of the start of the original analysis batch, it may be considered part of the original analysis batch. The reanalyzed sample(s) have the same QC requirements as above. However, reanalysis of the LFSM, and FD or LFMD are not required if they were already analyzed and passed QC requirements. Any newly prepared samples would require a full set of QC samples.
