Abstract
A method and apparatus for adjusting the raw, instantaneous response of an NDIR and determining a linear response therefrom is disclosed. The NDIR detector cell is connected to an output which is adjusted according to the function (Ax)/(1-x) where the coefficient A is a constant for the NDIR being used, and x is the raw, instantaneous, response of the detector. The coefficient A is determined by assessing the maximum response of the NDIR with an infinite mass of analyte within the sample cell.
