HPLC Method for Separation PVP on PVP by SIELC Technologies
High Performance Liquid Chromatography (HPLC) Method for Analysis of PVP
Polyvinylpyrrolidone (PVP)
Polyvinylpyrrolidone (PVP) is a versatile synthetic polymer widely used in life sciences and biochemical research. As a water-soluble compound, it performs multiple critical functions, including:
- Acting as a stabilizing agent
- Serving as an emulsifier and suspending agent
- Enhancing solubility of various compounds
- Functioning as a protective colloid
- Operating as a complexing agent
Its role as a protective colloid is especially important for stabilizing proteins, enzymes, and other sensitive biological molecules. This makes PVP particularly well-suited for forming stable complexes with iodine in pharmaceutical and medical formulations.
PVP can be retained and analyzed using the PVP column. The analysis utilizes an step gradient method with a simple mobile phase consisting of water, acetonitrile (MeCN), and ammonium acetate. Detection is performed using ELSD.
