Techniques for Optimizing GC Analysis of Ethylene Glycol in Water
15 Jan 2014The analysis of ethylene glycol in water is a very common test in environmental laboratories. Because ethylene glycol is highly soluble in water, it is not easily concentrated by purge and trap. This application note presents techniques for the GC analysis of ethylene glycol in water using direct injection with a Uniliner® liner, a polar capillary column, such as a Stabilwax® column, and multiple syringe washes between runs. Using these techniques can assist in attaining reproducible analyses with detection limits in the low ppm range.

Stabilwax® (Fused Silica)
Restek Corp.General purpose columns for FAMEs, flavor compounds, essential oils, solvents, xylene isomers, and US EPA Method 603 (acrolein/acrylonitrile). Resistant to oxidative damage. Temperature range: 40°C to 260°C. Equivalent to USP G14, G15, G16, G20, and G39 phases. The polar-deactivated surface tightly binds the Carbowax® polymer and increases thermal stability, relative to competitive columns.
