HPLC Method for Polyhexanide PHMB on PEI by SIELC Technologies
High Performance Liquid Chromatography (HPLC) Method for Analysis of Polyhexanide PHMB
Polyhexanide (polyhexamethylene biguanide, PHMB) is a polymer used as a disinfectant and antiseptic. We estimated that limit of detection is about 2 ppm for this compounds with this method.
The peak of polyhexanide fractionated on several peaks due to difference in length of the polymer components.
