Table 3 Risk of error in accuracy results (limit 10% difference) calculated using linearity regression parameters (range 20 μg/mL to 200 μg/mL)
From: A risk-based approach to validation of ion chromatography methods using suppressed conductivity
Accuracy level | Percent difference in calculated concentration (μg/mL) using response factor at accuracy level shown | ||||
|---|---|---|---|---|---|
20 | 50 | 100 | 150 | 200 | |
50% (25 μg/mL) | 3.7 | 2.8 | − 2.8 | − 4.8 | − 13.5 |
100% (50 μg/mL) | 2.6 | 1.6 | − 4.1 | − 10.1 | − 14.8 |
150% (75 μg/mL) | 12.2 | 11.3 | 6.2 | 0.7 | − 3.5 |
