[Recent advances of gas chromatography].

The recent advances and features of gas chromatography (GC) are briefly described. GC is a considered as a mature technique, and is applied in various fields. Now, in addition to stationary phases and columns, the investigations are focused on comprehensive two-dimensional gas chromatography (GC x GC), fast GC, portable GC, and micro GC (microGC). In the research of stationary phases, the room temperature ionic liquids continue its development, and modified cyclodextrins are other projects of GC stationary phases studied. Today a lot of chromatographers prefer to use commercial capillary GC columns rather than the home made one, and most of the stationary phases of commercial capillary GC columns used are 5% phenyl polydimethylsiloxane.
