An apparatus for determining the concentration of a first component in a mixture of at least two components, which have different absorption properties in the IR range, comprises image recording means (3; 24) which are adapted to image the mixture by means of IR radiation to produce at least one image. The apparatus further comprises image processing means (6, 26) which, with the aid of intensity values for pixels in the image which represent the mixture, determine the concentration of the first component in the mixture. <IMAGE> |
