Poly divinylbenzene porous beads GDX-103 are widely used in gas chromatography for the separation and analysis of complex mixtures. Their porous structure and hydrophobic nature make them ideal for adsorbing and separating volatile organic compounds (VOCs) and gases. They are particularly effective in environmental monitoring, where they help detect and quantify pollutants in air and water samples. Additionally, these beads are utilized in the petrochemical industry for analyzing hydrocarbon mixtures. Their thermal stability and chemical resistance ensure reliable performance in high-temperature applications. In pharmaceutical analysis, GDX-103 aids in the purification and separation of drug compounds, ensuring accurate and efficient results.
