Isojackets are external heating units that surround a pipe or tube to provide even and consistent heating.

A chromatograph separates the chemical components of a mixture. The substance moves through a column in either liquid or gas phase, and the components are separated by their affinity within the column. Gas-absorption chromatography was developed in the late 1940s, and by the mid-1960s commercial gas chromatographs dominated all forms of chromatography.
