Hi to all
By using M.C We can measure Moisture Present in our drug
By using LOD we can determine only Class-3 Solvents according ICH Q3C_R5 besides moisture content..







Only Class 3 solvents are likely to be present. Loss on drying is less than 0.5%.




If it is wrong please let me know right one
