The detector in which the liquid column effluent is fed continuously to a transport system, such as a moving belt, wire or chain, and after evaporation of the volatile components of the mobile phase the residue of less volatile components is burned to carbon dioxide and water.  1, fiche 1, Anglais, - transport%20detector

In this form of transport detector for h. p. l. c. [high-performance liquid chromatography], the eluate is deposited upon a fine stainless steel wire that has been cleaned by being heated at 850°C. The volatile solvent is evaporated and the solute oxidized at 700-800°C in air to a mixture of carbon dioxide and water. The oxidation products are mixed with hydrogen and passed over a nickel catalyst at 330°C to give methane which is burnt in a flame ionization detector to give an electrical signal that can be amplified and recorded. The detector gives a linear response over a wide concentration range [...] The sensitivity has been improved and the noise level reduced by using either a ceramic(kaolin) or ceramic-metal(kaolin and copper) coating to the wire.  1, fiche 2, Anglais, - wire%20transport%20detector
