Laboratories,
<br />Batch A distinct set of samples analyzed at a specific time
<br />Found Value of the QC Type of interest
<br />Limit Upper limit for RPD, in %.
<br />Lower Lower Recovery Limit, in % (except for LCSS, mg/Kg)
<br />MDL Method Detection Limit. Same as Minimum Reporting Limit Allows for instrument and annual fluctuations.
<br />PCM/SCN A number assigned to reagents/standards to trace to the manufacturer's certificate of analysis
<br />PQL Practical Quantitation Limit, typically 5 times the MDL
<br />QC True Value of the Control Sample or the amount added to the Spike
<br />Rec Amount of the true value or spike added recovered, in % (except for LCSS, mg/Kg)
<br />RPD Relative Percent Difference, calculation used for Duplicate QC Types
<br />Upper Upper Recovery Limit, in % (except for LCSS, mg/Kg)
<br />Sample Value of the Sample of interest
<br />R i
<br />Blanks Verifies that there is no or minimal contamination in the prep method or calibration procedure.
<br />Control Samples Verifies the accuracy of the method, including the prep procedure.
<br />Duplicates Verifies the precision of the instrument and/or method.
<br />Spikes/Fortified Matrix Determines sample matrix interferences, if any.
<br />Standard Verifies the validity of the calibration.
<br />B Analyte concentration detected at a value between MDL and PQL. The associated value is an estimated quantity.
<br />H Analysis exceeded method hold time. pH is a field test with an immediate hold time.
<br />L Target analyte response was below the laboratory defined negative threshold.
<br />U The material was analyzed for, but was not detected above the level of the associated value.
<br />The associated value is either the sample quantitation limit or the sample detection IimiL
