Common Applications for GC Headspace Residual Solvents The United States Pharmacopeia (USP) method 467 is a common headspace application. It detects and measures solvents from the pharmaceutical manufacturing process that may be present in over-the-counter and prescription drugs to ensure they meet regulatory guidelines and are safe for consumers. With the legalization of medical marijuana in many states and countries, residual solvents analysis also is being used for cannabis products. Analysis of USP Method Residual Solvents on the Agilent 8890 GC System. Novel Residual Solvents Analysis of Cannabinoid Products with the Agilent Headspace-GC/MS SystemBlood Alcohol Analysis Another widely used application of headspace gas chromatography is the determination of ethanol content in blood. Because these cases often go to trial, accurate and defensible data are critical. Analysis of blood alcohol concentration with an Agilent Intuvo 9000 GC system Blood Alcohol Analysis with the Integrated Agilent 8697 Headspace Sampler on 8890 GC-Dual FID SystemVolatiles in Environmental Samples Headspace-GC is used by environmental labs to analyze soil and water samples for the presence of volatile compounds that may pose a health risk to humans and animals. Fast Volatile Organic Compound Analysis of Drinking Water Using the Agilent 8697 Headspace Sampler in Tandem with Intuvo 9000 GC and 5977B GC/MSD Volatile Organic Compounds Analysis in Soils and Sediments Using the Agilent 8697 Headspace SamplerFlavor Compounds in Foods and Beverages Chemists use headspace sampling with gas chromatography to determine the volatile compounds in foods and beverages. Characterizing and quantitating them are critical to ensure product quality and consistency. Analysis of Flavor Compounds in Beer using the Integrated Agilent 8697 Headspace Sampler with the Agilent 8890 GC SystemThere are many other uses for headspace analysis, such as solvents and residual monomers in polymers; transformer oil gas analysis; contaminants in cleaning products, cosmetics, and personal care products; sterilization by-products in medical devices; and more.
