Method and a system for determination of somatic cells in milk
First Claim
1. A method for the assessment of the number of somatic cells in a liquid milk or milk product analyte material, comprisingarranging a volume of a liquid sample representing the analyte material in a sample compartment having a wall part defining an exposing area, the wall part allowing electromagnetic signals from the sample in the compartment to pass through the wall and to be exposed to the exterior, exposing, onto an array of active detection elements, an at least one dimensional spatial representation of said electromagnetic signals having passed through the wall part from the sample in the sample compartment, detecting the representation as intensities by individual active detection elements, processing the intensities in order to identify representations of electromagnetic signals from the somatic cells as distinct from representations of electromagnetic signals from background, correlating the results of the processing to the number of somatic cells in the liquid analyte material, and the size of the volume of the liquid sample being more than 0.01 μ
- l and the cells therein being identified by one exposure, that the assessment of the number of somatic cells fulfills a predetermined requirement to the statistical quality of the assessment based on substantially one exposure.

Abstract
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.
