Abstract: A spectrometric instrument comprising: a scanning interferometer having a beamsplitter for dividing incident optical radiation into a reflected beam, following a reflected beam path and a transmitted beam following a transmitted beam path; a monochromatic optical radiation source for launching a reference beam into the interferometer along a first propagation path to be initially incident on a first face of the beamsplitter; an observation optical radiation source for launching a divergent observation beam into the interferometer along a second propagation path to be initially incident on the first face of beamsplitter and overlap the reference beam at the first face; wherein the radiation sources cooperate to generate a first angle between the directions of propagation of the two beams along respective first and second propagation paths when initially and simultaneously incident at the first face which is larger than a divergence half-angle of the observation beam 64.

Abstract: A method for determining a degree of infection comprising the steps of i) preparing an un-isolated sample by adding a differentiating marker, suitably a meta-chromatic stain such as, for example, acridine orange to mammalian milk in an amount sufficient to provide a differentiation between cell types; ii) measuring a differential somatic cell count on the sample by means of a cytometer having a detection system sensitive to differences in the differentiating marker resulting from the marker becoming differently associated with different cell types in the sample; and iii) determining an indication of a degree of infection dependent on the measured differential cell count.

Abstract: The content of casein in milk is determined by two measurements of infrared absorbance in a milk sample by infrared spectrometry before and after a separation of the casein. The casein content is calculated by use of absorbance data recorded during the two absorbance measurements. The new method is considerable faster than the known wet-chemical methods, such as the normal wet chemical reference method for casein determination in milk using a Kjeldahl nitrogen determination of the milk sample, then a coagulation of the milk, and finally a Kjeldahl nitrogen determination of the filtrate. Further the new method provides a more reliable accuracy than the know determination using a single infrared analysis of a milk sample

Abstract: The invention provides a method for standardising an infrared spectrometer based on spectral patterns of constituents of atmospheric air naturally occurring in the spectrometer. The invention also provides a spectrometer applying the method. The method selects a spectral pattern in a recorded spectrum and determines a wavelength dependent position value for a feature, such as the centre of the pattern. This value is compared to a reference value that may be obtained from a spectrum recorded by a master instrument, and a standardisation formula can be determined. The absorption peaks from CO2 (g) around 2350 cm−1 are preferred as the selected pattern. The method renders the use of reference samples unnecessary and allows for the standardisation to be performed simultaneously with the recording of a spectrum of a sample of interest.
