There are two general types of column, packed and capillary (also known as open tubular). Packed columns contain a finely divided, inert, solid support material (commonly based on diatomaceous earth) coated with liquid stationary phase. Most packed columns are 1.5 - 10m in length and have an internal diameter of 2 - 4mm.

Swedish chemist Alfred Nobel solved this problem by mixing nitroglycerin with diatomaceous earth, a form of silica, to form a paste that was much safer to handle. Nobel’s dynamite was much more resistant to shock than straight nitroglycerin, and quickly became a popular explosive for civil engineering projects as well as for military use.

Diatomaceous earth filtration uses a mobile material to build up a filter wall on a membrane. Diatomaceous earth (DE) is a fine, powdery substance comprising the skeletons of diatoms (microscopic algae). It occurs as natural deposits, which are mined, dried, graded and bagged. The usual source is the USA.
