'Batch A distinct set of samples analyzetl at a specifc lime
Found Value of the QC 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/standards to trace to the manufacturer's certificate of analysis
P(7L Practical Cuantitation Limit, typically 5 times [he MDL.
CC 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 far LCSS, mgMg)
RPD Relative Percent Difference, calculation used for Duplicate DC Types
Upper Upper Recovery Limit, in % (except for LCSS, mg/Kg)
Sample Value of the Sample of interest

Blanks Verifies that there is no or minimal contamination in the prep methotl or calibration procedure.
Control Samples Verifies the accuracy of the method. including the prep procedure.
Duplicates Verifies the precision of the instrument and/or method.
SpikeslFortifed Matrix Determines sample matrix interferences, if any.
Standard Verifies the validity of the calibration.
~ ~ .
B Analyte concentration detected at a value between MDL and PCL.
H Analysis exceeded method hold time. pH is a field test with an immediate hold time.
R Poor spike recovery accepted beceuse the other spike in the set tell within Iha given limits.
T High Relative Percent Difference (RPD) acceptetl bequse sample concentrations are less than 10x the MDL.
U Analyle was analyzed for but not detected al the indicated MDL
V High blank data accepted because sample concentration is 10 times higher than blank concentration
W Poor recevery for Silver quality control 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.
