SECTION D-1. QC INFORMATION – Instrument Calibration

1. Calibration Curve: Were a series of standards 

within the standard range and one blank used to 

create a calibration curve? (4500 CN E/4a)

What were the concentrations of the calibration 

standards used by lab? 

2. Calibration Curve Verification (CCV): Was the 

calibration curve checked periodically including 

every time the lab prepared a new reagent? (4500 

CN E/4a)

If provided, what were results reported for the 

CCV?

SECTION D-2. QC INFORMATION –Blanks/Duplicates

1. Laboratory Blank: Was a blank (0.0 mg CN-/L) 

prepared and analyzed containing NaOH dilution 

solution and all solutions added to the samples? 

Note any contamination reported by the 

laboratory.

SECTION E. DETAILED RAW DATA REVIEW – Sample Results

1. Calculation: Was the concentration in samples 

determined using the standard curve and were 

values reported in mg/L? (4500 CN E/5)

2. Dilution: Were only results between 5 and 20 

ug/L reported and if a result was ≥ 20 ug/L, was 

the sample diluted and reanalyzed? (4500 CN A 

3a)
