Definition
CCV : Continuing Calibration Verification - Analyzed to verify the instrument calibration is within criteria.
Blank : Method Blank - Prepared to verify that the preparation process is not contributing contamination to the samples.
Matrix Spikes - A random sample is spiked with a known amount of analyte. The recoveries are an indication of how that sample
MS
matrix affects analyte recovery.
: Matrix Spike Duplicate of MS/MSD pair - A random sample duplicate is spiked with a known amount of analyte. The recoveries
MSD
are an indication of how that sample matrix affects analyte recovery.
: MS/MSD Relative Percent Difference (RPD) - The MS relative percent difference is an indication of precision for the preparation
MSRPD
and analysis.
ND : Non -detect - Result was below the DQO listed for the analyte.
DQO : Data Quality Objective - This is the criteria against which the quality control data is compared.
