Abstract
A method and apparatus for processing the signal produced by the detector of a chromatographic analysis apparatus, wherein the detector signal is monitored over a fixed period of time, so spaced from a 'start' time origin as to include the approach to and fall from maximum concentration of one gaseous constituent flowing through the detector, and wherein the signal strength indicative of the maximum concentration of the constituent within the time period is detected and stored in an afferent index memory and the stored value of the signal is utilized to generate a value directly representative of the proportion of the constituent attaining maximum value within the time period.
