Separation of Neopentane in Hydrocarbon Mixture Using Helium and Hydrogen Carrier Gas–Facilitated by Pro EZGC Chromatogram Modeling

Neopentane is an impurity in C4 hydrocarbons streams, such as 1,3-butadiene, n-butane, and butylene. It is used in a variety of applications from the production of adhesives, paints, and inks to the blowing agent in the production of polystyrene foam. While neopentane analysis is performed more frequently than in the past, chemists often have difficulty separating neopentane from other hydrocarbons due to column limitations. The unique stationary phase of Rt- Alumina BOND/MAPD columns is highly selective for C1-C5 hydrocarbons, offering excellent separation of neopentane and other impurities. The high loading capacity provides exceptionally symmetrical peaks, making these columns ideal for impurity analyses at ppm concentrations. Rt-Alumina BOND/MAPD columns are manufactured using an innovative bonding process that reduces particle generation and release, resulting in robust and reproducible retention and flow. Restek’s Pro EZGC platform has expanded to include PLOT functionality, allowing users to accurately model retention characteristics and optimize GC conditions without timely trial-and-error.
