WebApr 12, 2024 · The conventional reverse fill/flush flow modulation for comprehensive two-dimensional gas chromatography requires a bleed capillary column to be connected to the outlet of the modulator channel. The purpose of this capillary, that does not contain the stationary phase, is to provide a pressure resistance to the modulator channel flow. WebJan 9, 2024 · Capillary action is defined as the spontaneous flow of a liquid into a narrow tube or porous material. This movement does not require the force of gravity to occur. In fact, it often acts in opposition to gravity. Capillary action is sometimes called capillary motion, capillarity, or wicking. WebCapillary GC columns are best suited for highly sensitive assays. Capillary columns consist of a thin, fused silica glass tube in which the stationary phase is chemically bonded or coated to the inner column surface. Non-polar GC columns are best suited for the analysis of non-polar compounds (e.g. alkanes). la x tunein
