Main purpose of a recorder is to record electrical and non-electrical quantity as a function of time. Graphic recorders use elementary rudiments like chart paper for displaying and storing the physical quantity and pen for marking the variation in physical quantity. Chart paper is passed through the recorder at constant rate. The recorder itself becomes a device for measuring retention time. A certain number of inches or centimetres of chart paper corresponds to a certain number of minutes.

Analog signal from the chromatograph may be connected to a recorder with chart paper speed of 5 min/in. during an analysis to measure Glutethimide concentrations in the serum and cerebrospinal fluid (CSF) using gas chromatography.
