Poly divinylbenzene porous beads GDX-103 are widely used in gas chromatography for the separation and analysis of volatile organic compounds and high boiling point compounds. Their porous structure and high surface area make them effective in adsorbing and separating complex mixtures, including trace water analysis. They are particularly useful in environmental monitoring to detect pollutants in air and water. In the pharmaceutical industry, these beads aid in the purification and analysis of drug compounds. Additionally, they are employed in food and beverage testing to ensure quality and safety by identifying contaminants or additives. Their thermal stability and chemical resistance make them suitable for high-temperature applications in various analytical processes.
