AN246: Determination of Diethylene Glycol in a Sorbitol Solution
Description
Glycerin, sorbitol, and propylene glycol (PG) are widely used in pharmaceuticals and personal care products. These products are at risk from adulteration by similar, less costly, and very toxic compounds (ethylene glycol (EG) and diethylene glycol (DG)). The United States Pharmacopeia (USP) as directed by the US FDA revised USP 32 NF 26–27 monographs to identify and quantify EG and DEG in PG, sorbitol, and glycerin solutions. Here DEG in sorbitol solution is determined by IC-PAD with Pt working electrode. An ICS-6000 can be used for this application.Market: | Pharma |
