Sentence examples for replicate determination from inspiring English sources
The precision of amperometry was found to be 1.9% for replicate determination of a 49.0 μM solution of AA (n = 6).
Values for parameters not determined were assigned non-zero values using (in order of preference): (1) the replicate determination value (samples with designation "R" in the name in Table 1, or (2) the value of a non-replicate determination made at the same site (e.g., 00-LL1 and 99-LL1).
The following expression was used: LOD = 3.3 σ/s and LOQ = 10 σ/s where σ is the standard deviation of the values obtained by replicate determination of blank and s is the slope of the calibration curve.
The detection limit (LOD) for the proposed methods was calculated using the following equation according to IUPAC definition (23): LOD = 3s/k; where s is the standard deviation of replicate determination values under the same conditions as the sample analysis in the absence of the analyte, and k is the sensitivity, namely the slope of the calibration graph.
LOD and LOQ were calculated as 3.3 σ/s and 10 σ/s, respectively, as per ICH definitions, where, σ is the mean standard deviation of replicate determination values under the same conditions as the sample analysis in the absence of the analyte (blank determination), and s is the sensitivity, namely the slope of the calibration graphs.
Coefficient of variation (CV) for replicate determination was <4% for neutrophils and lymphocytes.
The limit of detection was determined from 20 replicate determinations of the zero standard and is defined as the value two standard deviations above the mean of the 20 replicates.
