The paper describes methods of analyses in direct determination of fat, protein and lactose. The Infrared Milk Analyser (IRMA) its fundamental component a double‐beam infrared spectrophotometer which compares the absorption of a milk sample at specific wavelengths is described in detail. Calibration of the IRMA is discussed and the comparison of infrared and chemical analyses shown.
