The application of planar microfluidic devices in GC for the separation of components of interest otherwise difficult to separate in a single analysis is presented. A variety of configurations were used for parallel chromatography, column effluent splitting, back flushing, selectivity tuning, valve less switching and column isolation, heart cutting, and comprehensive multidimensional chromatography. The synergies of recently commercialized planar microfluidic devices combined with the resolving power of fused-silica capillary columns are demonstrated. Difficult separations were accomplished in one single analysis, such as light hydrocarbons in air with high-moisture content, fixed gases in hydrocarbons, trace sulfur containing compounds in natural gas, and oxygenated compounds in hydrocarbons, among others.
平面微流控器件在 GC 中应用于分离单分析中难以分离的感兴趣的成分。多种配置用于并行色谱、柱洗脱分流、反冲洗、选择性调谐、无阀切换和柱隔离、心切割以及多维色谱。最近商业化的平面微流控器件与熔融硅毛细管柱的分辨率相结合的协同作用得到了证明。在一次单分析中完成了困难的分离,例如空气中的轻烃与高湿度、烃类中的固定气体、天然气中的痕量含硫化合物以及烃类中的含氧化合物等。
