Question
What is the expected precision and sensitivity of the Total Kjeldahl Nitrogen Method 8075?
Summary
Total Kjeldahl Nitrogen Method 8075 Performance
Answer
The method performance data that follows was derived from laboratory tests that were measured on a spectrophotometer during ideal test conditions. Users may get different results under different test conditions. For program 399 with a 76 mg/L NH3–N standard the precision (95% confidence interval) was 70–82 mg/L NH3–N and the sensitivity concentration change per 0.010 Abs change was 1 mg/L NH3–N.
