Performance Characteristics:
The study director has made an error in the evaluation of bias against the NIST by reporting the wrong
certified value for NIST 1849a. The method actually shows no bias against the NIST value when using the
correct value.
Analytical Range:
0.05-10 meets SMPR limits (0.12-5.1 µg/100g)
LOQ:
4.58 ng/100g meets SMPR limits (<0.12 µg/100g)
Accuracy/Recovery:
103% average (101-103%) meets SMPR limits (90-110%).
Acceptable bias against NIST1849a SMPR
Precision (RSD
r
):
2.3% meets SMPR limits (<11%)
Reproducibility (RSD

System suitability:
No details
Recommendation:
Not recommended First Action at this time.
