摘要: The classification of stationary phases and the selection column dimensions for gas chromatography are described. Column is based on system constants solvation parameter model determined at several temperatures nearly all common types poly(siloxane), poly(ethylene glycol), ionic liquid phases. Data analysis tools used to identify columns with different selectivities from a large database explain selectivity differences in terms capability particular intermolecular interactions. effect temperature limitations current models temperature-programmed separation discussed. Suitable approaches method translation fast Coupled tuning identification orthogonal-like comprehensive two-dimensional complete discussion optimization.
