Conc. based on:
test mat.
Incubation duration:
>= 24 - <= 72 h
20 °C
Details on results:
- System suitability: System suitability meets the acceptance criterion as the % RSD obtained was 0.73% to 4.70% which is less than 5.0%.
- Specificity: Specificity meets the acceptance criterion for the test substance as the interference obtained for diluent was 4.86% which is < 30% of the standard response at LOQ.
- Limit of Detection (LOD) and Limit of Quantification (LOQ): The LOD was determined at 9.45 mg/L and LOQ was determined at 23.61 mg/L
- Linearity: Linearity meets the acceptance criterion as the correlation coefficient obtained was 0.9992 to 0.9999 which is > 0.99.
- Accuracy (% Recovery) and Precision (% RSD): Recovery meets the acceptance criterion as the % recovery obtained was 102.86% for LOQ and 96.59% for 10 LOQ which is within the range 70% to 110% of the nominal concentration at each fortification level. Precision meets the acceptance criterion as the % RSD obtained was 3.20% for LOQ and 6.00% for 10 LOQ which is < 20%.
- Preliminary Test: Preliminary result indicated that the test item had a solubility of more than 10^-2 g/L in milli-Q water.
- Definitive Test: The solubility of the test substance in Milli-Q water was determined to be 242.37 mg/L for 24 hours, 258.44 mg/L for 48 hours and 255.83 mg/L for 72 hours at 20°C.
