smooth inner wall of the tube (wall-coated open-tubular (WCOT) column). The inner wall may be made porous by etching the surface by chemical means or by depositing porous particles on the wall from a suspension, the porous layer acting as the stationary phase or as a support for a liquid (porous-layer open-tubular (PLOT) column); or the porous layer may consist of support particles deposited from suspension (support-coated open-tubular (SCOT) column). The term capillary column denotes a column (packed or open-tubular) having a small diameter.

With a solid stationary phase, separation is based mainly on adsorption affinities between the sample molecules and the surface of the active solid (adsorption chromatography). With a liquid stationary phase separation depends on the solubilities of the sample molecules (partition chromatography). In keeping with other partition processes, the sample molecules are often referred to as the solute and the stationary phase as the solvent. This terminology is acceptable in gas chromatography, but can cause confusion in liquid chromatography.

Global warming is a huge problem which will significantly affect every country in the world. Many people all over the world are trying to do whatever they can to help combat the effects of global warming. One of the ways that people can fight global warming is to reduce their dependence on non-renewable energy sources like oil and petroleum based products.
