3.4.3 Limit of detection (LOD) and limit of quantitation (LOQ): LOD was determined by
considering signal to noise (S/N) ratio of 3:1 for the strongest mass transition with respect to the background noise obtained from the blank sample whereas LOQ was determined similarly by
considering signal to noise ratio (S/N) ratio of 6:1. Based upon the mean noise level for the ten injections of the matrix blank of injectable suspension sample, lowest detection limit of the instrument was calculated as 0.05mg/g and confirmed using standard solutions with concentration of 0.05mg/g and the lowest concentration levels that could be quantified with
reproducible values obtained on injecting 6 replicates of the same concentration as 0.1mg/g and
further confirmed by injecting 6 replicates of matrix matched standard solution of Benzyl
alcohol having concentration of 0.1mg/g.
