Achieving Optimum GC Separation – Designing New Capillary Column Stationary Phases Using Computer Modeling

Column Watch guest authors describe methods to predict optimal stationary phases, which enable more rapid and improved gas chromatography column development. By calculating optimal stationary-phase composition and physical parameters, column developers can construct columns that provide the exact separation requirements desired by analysis or current methods.

Figure 2. Split injection used to measure triplicate test of MTBE, hexane, o-xylene, and 1-methylnaphthalene comparing different solvents (methanol, methylene chloride) and column insertion distances starting with 0.5 mm, 5.0 mm, 10.0 mm, 15 mm, and 20.0 mm. Methanol had the best performance at the 5.0 mm insertion distance and methylene chloride looked slightly better at the 0.5 mm. We would still recommend not going below the 5.0 mm manufacturer recommended insertion distance.
