Technical Overview

FTS module
This module uses a Fourier Transform Spectrometer (or FTIR) to capture the complete infrared absorption spectrum of the milk sample for component analysis. Collecting the complete spectrum allows the calibration to be based on multiple spectral characteristics of each particular component. The optical deck of the FTS is housed in a hermetically sealed enclosure, ensuring enhanced temperature stability and environmental robustness. The air in the sealed deck is pumped out, leaving the deck under vacuum. The combination of the hermetic seal and removing the humid air greatly reduces the humidity load on the enclosed desiccant, virtually eliminating the preventative maintenance task of frequent desiccant regeneration.

FCM module
The FCM is based on proven flow cytometry methodology for somatic cell counting. This system uses a proprietary process based on the principle of laser-based flow cytometry to determine the somatic cell count in raw milk. Flow cytometry is an extremely powerful and versatile technique and is the method of choice in the medical field for detecting, analysing and sorting cells. The Somacount FCM is the result of 15 years of experience and research in flow cytometry; the first instrument was developed in 1991.

What is Flow Cytometry?
Flow cytometry is a technique use to rapidly characterise and enumerate populations of bacteria, somatic cells and other particles contained in a liquid matrix.

The flow cytometer, also known as the counting assembly, includes the flow cell, microscope, narrow band filter, and one or two powerful and highly stable solid-state laser(s) and highly sensitive photomultiplier(s). The laser excites the
fluorescent marker that is intercalated into the DNA and/or RNA. The fluorescence output is then collected with optics, filtered with a narrow band filter, and detected with the photomultiplier(s). The intensity and width of the fluorescence pulses are recorded and used as gating parameters. A calibration or conversion equation can be applied to convert instruments’ gated pulses into relevant reference method official unit. The flow cytometer is compact, completely closed and temperature regulated to provide optimum stability.
