A General Strategy to Rapid and Sensitive Determination of Five High Boiling Point Solvents in Pharmaceuticals by RP-HPLC Combined with Precipitation Method
{{output}}
The difficulty on determination of high boiling point solvents, always exist due to their low vapor pressure in headspace (HS) vial. What's worse, the commonly used GC diluents, such as N, N-dimethylacetamide, 1,3-dimethyl-2-imidazolidinone, dimethyl sulfoxide... ...
