DairySpec-Combi Series: DairySpec FT & SomaCount FC

DairySpec-Combi Series: DairySpec FT & SomaCount FC

Simultaneous Somatic Cell and Component Analysis

Automatic versions from 100 up to 300 samples/hour

System that combines the DairySpec FT for component analysis and the SomaCount FC for Somatic Cell Counting. The combination of these two flagship methods provides a complete overview of milk chemical and hygienic composition by analysing up to 64 parameters simultaneously. Different versions of DairySpec Combi are available (100, 150, 200, 250, 300) up to a maximum speed of 300 samples/hour.

The sampling, sequencing and identification of the sample vials are functions performed by the Autosampler.

Compatible with the ILAS 3000 ROBOT: Automation System for Milk Analysers

Technical Overview

Technical Overview

The DairySpec FT consists of a proprietary optical infrared analysis system and an integrated high speed computer. To measure specific components within milk products, the instrument measures the energy absorption at specific wavelengths in the mid-infrared region.

Operators use computer controls to vary the pump and analysis speed, directing the system to operate at a slower speed when processing products of high viscosity, such as cream.
Programmable screen layout allows the operator to choose up to eight windows to display component values, both measured and calculated.
The instrument is capable of handling multiple calibrations as needed to optimise accuracy in testing different components.
Operator friendly software with graphic user interface (GUI) helps make the system easy to operate.
The flexible design of the instrument allows it to be used as a product analyser capable of testing a wide variety of fluid dairy products.
Instrument durability allows for use in high volume testing environments.
State-of-the-art design utilises few moving parts, making the system very easy to maintain.
Small, compact size and integrated computer reduces the amount of bench space needed, allowing the system to be used in the smallest of laboratories.

The SomaCount 150 uses a proprietary process based on the principle of laser-based flow cytometry to determine the somatic cell counts in a milk sample.

A milk sample is taken automatically and mixed with a fluorescent dye solution.
This dye disperses the fat globules and stains the DNA in the somatic cells.
An aliquot part of the stained suspension is injected into a laminar stream of carrier fluid.
The somatic cells are separated by the stream and exposed to a laser beam.
As the stained cells pass through the excitation source (laser beam), they begin to fluoresce creating a light pulse.
Through a series of lenses, the fluorescent pulses are focused onto a photo-multiplier tube, where they are converted into electrical pulses.
The pulses are sorted and stored by size using a micro-controller. By using a process known as pulse height analysis, the pulses are sorted, counted and translated into a somatic cell count.
The software allows for a wide variety of data output options, including diskette, serial, parallel and network connections which can be easily formatted to fit into the user’s existing system.
Operator friendly software with graphic user interface (GUI) helps make the system easy to operate.
The Somacount FC meets the requirements of IDF standards for somatic cell counting. It is an AOAC approved methodology.

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.
