Batch A distinct set of samples analyzed at a specific time
Fouts Value of the DC Type of interest
Limit Upper limi for RPD, in %.
Lower Lower Recovery Limit, in % (except far LCSS, mglKg)
MDL Method Detection Limi. Seine as Minimum Reporting Limit. Albws for instrument and annual fluctuations.
PCAVSCN A number assigned to reagents/standards !o trace to the manufacturer's certificate of arta)ysis
POL - Practical Duantitation Limit, typically 5 times the MDL.
QC Tme 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, rrg/l(g)
RPD Relative Percent Difference, calculation used for Duplicate OC Types
Upper - Upper Recovery Limit, in % (except for LCSS, mgMg)
Serrrp'e - Value of the Sample o(interest

Blanks Vedfies that there is no ar minimal contamunation in the prep method procedure.
Control Samples Verifies the accuracy of the method, induding the prep procedure.
Duplicates Verifies the Drecisbn of the instmment andlor rrethod.
SptkralFortified Matrix Determirres sample matrix interferences, i any.
B Analyte concentration detailed at a value between MDL and PDL.
H ~ Analysis exceeded method hold lima. pH is a field test with an immediate hold time.
R Poor spice recovery accepted because the other spike in the set fell within the given knits.
T High Relative Percent Difference (RPD) accepted because sample concentrations are less than 1(bc the MDL.
U Anayte was analyzed for but not detected at the indipled MDL
V High blank data accepted because sample concentration is 10 times higher than blank concentm6on
W Poor recovery (or Siver quaky control s accepted because Silver often precipitates with Chloride.
X Dualtry control sample is out of corrtrol.
Z Poor spike recovery is accepted because sample concentration s four times greater than spike ooncenlratan.
