Researchers from Dow Chemical Company (Midland, Michigan) used headspace sampling with gas chromatography to analyze the concentration and identity of compounds in the vapor above six ionic liquids at a temperature of 100 ?C.
Researchers from Dow Chemical Company (Midland, Michigan) used headspace sampling with gas chromatography to analyze the concentration and identity of compounds in the vapor above six ionic liquids at a temperature of 100 C. The researchers also determined detection limits and measured the partition coefficients of 10 compounds. The results showed that the technique is useful in quantitating compounds in vapors above ionic liquids.
HPLC 2025 Preview: Functionalized Monoliths as Selective Sample Preparation Materials
May 16th 2025Analyzing trace compounds from complex samples often requires purification and pre-concentration, and online coupling of solid-phase extraction (SPE) with liquid chromatography (LC) helps minimize analysis time and solvent/sample use. Monoliths with large macropores are ideal for this coupling due to their low back pressure and versatility in various formats.
