ACZ Laboratories, Inc.
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 antl annual fluctuations.
PCN/SCN A number assigned to reagents/standards to trace to the manufacturer's certificate of analysis
PQL Practical ~uantitation 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 usetl for Duplicate DC Types
Upper Upper Recovery Limit, in °h (except for LCSS, mg/Kg)
Sample Value of the Sample of interest
AS Analytical Spike (Post Digestion) LCSWD Laboratory Control Sample -Water Duplicate
ASD Analytical Spike (Post Digestion} Duplicate LFB laboratory Fortified Blank
CCB Continuing Calibration Blank LFM Laboratory Fortified Matrix
CCV Continuing Calivation Verification standard LFMD Laboratory Fortified Matrix Duplicate
DUP Sample Duplicate LRB Laboratory Reagent Blank
ICB Initial Calibration Blank MS Matrix Spike
ICV Initial Calibration Verifcation slantlard MSD Matrix Spike Duplicate
ICSAB Inter-element Correction Standard - A plus B solutions PBS Prep Blank • Soil
LCSS Laboratory Control Sample -Soil PBW Prep Blank -Water
LCSSD Laboratory Control Sample -Soil Duplicate PQV Practical Quantitalion Verification standartl
LCSW Laboratory Control Sample -Water SDL Serial Dilution
Blanks Verifies that there is no or minimal contamination in the prep methotl or calibration procedure.
Control Samples Verifes the accuracy of the method, including the prep procedure.
Duplicates VenLes [he precision of the instrument antl/or method.
Spikes/Fortifed Matrix Determines sample matrix interferences, if any.
Standard Verifies the validity of the calibration.

B Analyle concentration tletectetl at a value between MDL antl PQL.
H Analysis exceetled method hold time. pH is a feld test with an immediate hold lime.
R Poor spike recovery accepted because the other spike in the set fell within the given limits.
T High Relative Percent Difference (RPD) accepted because sample wncentrations are less than 10z the MDL.
U Analyte was analyzed for but not tletecled at the indicated MDL
V High blank data accepted because sample concentration is 10 times higher than Dlank concentration
W Poor recovery for Silver quality control is acceptetl Decause 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.
