ACZ
Laboratories,
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 reagenlslstandards to trace to Ine manufacturers certificate of analysis
PQL Practical Quantization Limit, typically S limes 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 9C Types
Upper Upper Recovery Limit, in % (except for LCSS, mg/Kg)
Sample Value of the Sample of interest
AS Analytical Spike (Post Digestion) LFM Laboratory Fortifietl Matrix
ASD Analytical SDike (Post Digestion) Duplicate LFMD Laboratory Fortified Matrix Duplicate
DUP Sample Duplicate LRB laboratory Reagent Blank
LCSS Laborelory Control Sample -Soil MS/MSD Matrix Spike/Matrix Spike Duplicate
LCSW Laboratory Control Sample -Water PBS Prep Blank -Soil
LFB Laboratory Fonified Blank PBW Prep Blank -Water
Blanks Verifies that there is no or minimal contamination in the prep method procedure.
Control Samples Verifies the accuracy of the method, including the prep procedure.
Duplicates Verifies the precision of the instrument and/or method.
Spikes/Fortifietl Matrix Determines sample matrix interterences, if any.
B Analyze concentration detected at a value between MDL and PUL.
H Analysis exceeded method hold time. pH is a Feld test with an immediate hold time.
R Poor spike recovery aceepted because the other spike in the set fell within the given limits.
T High Relative Percent Difference (RPD) accepted because sample concentrations are less than tOx the MDL.
U Analyze 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 control is accepted because Silver often precipitates with Chloride.
% t]uality control sample is out of control.
Z Poor spike recovery is accepted because sample concentration is four times greater than spike concentration.
