I have an issue about PEG3350 residual solvents test (Ethylene oxide, 1,4Dioxane). I am using GC/HS-FID method for the analysis. When I tried to do Accuracy test for the analytical method validation my recoveries too low (%30-%10) for both residual solvents. My method is a validated method from manufacturer.
In my opinion this could be related with distrbution of EO and DO in polyethelen glycol. But i can not solve it.
Thank you for answers.
