USP <467> Analysis of Residual Solvents
ALS Environmental tests residual solvents as specified in USP <467> (United States Pharmacopeia). We utilize a headspace GC instrument for analyzing the various residual solvent classes. We offer method feasibility, development and validation.
As part of a standard residual solvent analysis, CAS will report all Class 1 and Class 2 solvents that are amenable to GC headspace analysis as defined in USP <467> and shown to work in practice.
To confirm the reportable list, each new test article will undergo a method suitability study to identify potential matrix interferences prior to sample analysis. This study includes an evaluation of any significant chromatographic interferences or signal suppression caused by the test article itself. This pre-evaluation of each material helps avoid lengthy delays caused by suspect results due to method limitations, and also provides additional data defensibility for FDA submissions.
