Batch A distinct set of samples analyzed at a specific time
Found Value of the DC Type of interest
Limit Upper limit for RPD, in %.
Lower Lower Recovery Limit, in % (except for LCSS, mg/Kg)
MDL Method Detection Limit. Same as Minimum Reporting Limit. Allows for instrument and annual fluctuations.
PCN/SCN A number assigned to reagents/standartls to trace to the manufacturer's certifcafe of analysis
PQL Practical Quantitation Limit, typically 5 times the MDL.
QC True Value of the Control Sample or the amount added to the Spike
Rec Amount of the true value or spike added recovered, in % (except for LCSS, mg/Kg)
RPD Relative Percent Difference, calculation used for Duplicate QC Types
Upper Upper Recovery Limit, in % (except for LCSS, mg/Kg)
Sample Value of the Sample of interest

Blanks Verifes that there is no or minimal contamination in the prep method or calibration procedure.
Control Sa mples Verifies the accuracy of the method, inclutling th e prep procedure.
Duplicates Verifes the precision of the instrument and/or m ethod.
SpikeslFOrtifed Matrix Determines sample matrix interferences, if any.
Standard Verifes the validity of the calibration.
. • .
B Analyte concentration detectetl at a value between MDL and PDL.
H Analysis exceeded method hold time. pH is a feld test with an immediate hold time.
R Poor spike recovery accepted because the other spike in the set fell within the given limits.
T High Relative Percen( Difference (RPDj accepted because sample concentrations are less than tOx the MDL.
U Analyte was analyzed for but not detected at the indicated MDL
V High blank data accepted because sample concentration is 10 times higher than blank concentration
W Poor recovery for Silver quality wntrol is accepted because Silver often precipitates with Chloride.
X Duality control sample is out of control.
Z Poor spike recovery is accepted because sample concentration is four times greater than spike concentration.
