Injecting too much sample onto a chromatographic system will eventually overload the column. Analytical chemists are concerned about column overloading because it reduces column efficiency, and, as a result, the resolution is sacrificed. Surprisingly

Solid adsorbents have unique selectivity and characteristics that result in separations that are not possible using liquid stationary phases. The adsorption process allows the retention of very volatile components at higher temperatures, which create

The application of vacuum GC has several advantages over pressurized GC. One of the key characteristics is that the optimal gas velocity is very high. Combined with short capillary columns of wide internal diameter, this results in short analysis tim

Comprehensive two-dimensional gas chromatography (GC × GC) is based on a coupling of two GC columns of different characteristics by means of a device that allows portions of the effluent from the primary column to be injected onto the second dimensi

In gas chromatography (GC), the main driver for the separation is the stationary phase, which is deposited on the inside wall of capillary columns. Many developments have taken place in the past 20 years. The stationary phases used in GC are liquid p

In this chapter the chromatographic behavior of several volatile compound classes is discussed, when analyzed using the most current stationary phase and column technologies. Most of the applications shown are performed using gas-solid chromatography

There is a constant drive to speed up GC separations. Shorter analysis times provide more analyses per day, which reduces cost. One approach is to reduce column length and column diameter and columns of 0.15 mm i.d. have indeed grown in popularity. H

The separation of isomers and enantiomers of branched C10-C12 phenylalkanes by gas chromatography on fused silica capillary columns coated with some modified β- and γ-cyclodextrins was studied. It was shown that the separation of positional isomers
