The present invention relates to a method for the assessment of quantity and quality parameters of biological particles in a liquid analyte material. The method comprises applying a volume of a liquid sample to an exposing domain from which exposing domain electromagnetic signals from the sample in the domain can pass to the exterior, and exposing, onto an array of active detection elements such as CCD-elements, a spatial representation of electromagnetic signals having passed from the domain, the representation being detectable as an intensity by individual active detection elements, under conditions permitting processing of the intensities detected by the array of detection elements during the exposure in such a manner that representations of electromagnetic signals from the biological particles are identified as distinct from representations of electromagnetic signals from background signals. The size of the volume of the liquid sample is sufficiently large to permit the assessment of the quantity and quality parameters to fulfill a predetermined requirement to the statistical quality of the assessment based on substantially one exposure.

Assessment of the number of somatic cells in a liquid milk or milk product analyte material comprises arranging a volume of a liquid sample representing the analyte material in a sample compartment and allowing electromagnetic signals from the sample in the compartment to pass through and be exposed to the exterior. There is exposed onto an array of active detection elements, an at least one-dimensional spatial representation of electromagnetic signals from the sample. The representation is detectable as an intensity by individual active detection elements. Representations of electromagnetic signs from the somatic cells are identified. The size of the volume of the liquid sample is sufficiently large to permit the assessment of the number of somatic cells to fulfill a predetermined requirement to the statistically quality of the assessment based on substantially one exposure.

An infrared attenuation measuring system, for the quantitative determination of the concentration of one or more components in an aqueous fat-containing sample, such as milk, by an infrared attenuation technique. The system comprising a set of waveband-related parameters containing information enabling the system to calculate the concentrations substantially independent of the degree of homogenization of the fat-containing sample, and/or to determine the degree of homogenization of the sample. The parameter set contains parameters which are related to wavebands containing a high degree of information about the homogenization degree of the sample. This may be wavebands containing little information about the chemical components of the sample, and/or wavebands containing a substantial amount of information about the chemical components of the sample. The system is calibrated with aqueous fat-containing samples with different degrees of homogenization. The calculating means may be a microprocessor calculating the concentration of the component or components in question, or a neural network defined by the wave band-related parameters. The wavebands in which the attenuation values are determined in the infrared attenuation measuring means may be defined by optical filters, stationary grating and movable and/or multiple detectors, or by movable grating and one or several stationary or movable detectors. The infrared attenuation measuring means may comprise an interferometer, the data obtained from the interferometer being processed using Fourier transformation; and infrared attenuation measuring means of this type may be a FTIR spectrophotometer.
