Poly divinylbenzene porous beads GDX-201 are widely used in gas chromatography as a stationary phase for the separation and analysis of volatile organic compounds. Their porous structure and hydrophobic nature make them particularly effective for analyzing gases and low-boiling-point substances, such as hydrocarbons, alcohols, and esters. These beads are also employed in environmental monitoring to detect and quantify pollutants in air and water samples. Additionally, they serve as adsorbents in purification processes, effectively removing impurities from gases or liquids. Their thermal stability and chemical resistance further enhance their utility in high-temperature applications and harsh chemical environments.
