Detection apparatus, particularly for use in liquid chromatography

摘要

A detection apparatus of a simple construction is formed from an electro-chemiluminescence cell (12) having connections for the supply and the discharge of a liquid to be examined, particularly a mobile phase coming from the separation column of a liquid chromatograph, a voltage source (11) and a detector (14) for electric current, which are connected to the electrodes (1, 2) of the cell (12). Preferably a radiation-sensitive element (13) is also provided.
