Regarding Residual solvents by GC, we are using Dimethylsulfoxide (DMSO) as blank solution in our analysis and validation also done. Now we are going to change 1-methyl-2-pyrrolidone(NMP) as blank solution instead of DMSO due to peak separation for required solvents and rest method is same. In this view, pleas help me
- should be considered as a new method
-which validation parameters are required for validation - how can we show the equivalence
- guideline reference, if any
- any other suggestions
