Differential SCC for improved mastitis management

Differential somatic cell count (DSCC) is a new milk testing parameter introduced with the Fossomatic™ 7 DC analyser. It complements the established test for total number of somatic sells (SCC) pioneered by FOSS in the 1980’s. The Fossomatic™ 7 DC has several sensors detecting fluorescence signals from milk cells and a new chemistry and an incubation unit. Combined, they enable the instrument to measure DSCC and SCC simultaneously.

Diamond cuvette for improved robustness ensures maximum uptime

MilkoScan™ 7 RM has a diamond cuvette backed by 10 years guarantee. Optics are optimized on the interferometer module increasing the signal/noise ratio, ensuring the same high performance at all cadences and improving repeatability for minor constituents.

Adulteration – untargeted raw milk screening

Raw milk containing abnormalities is a growing problem. The abnormalities can be caused by deliberate adulteration, for example, with lard or melamine or by accidents if water or cleaning agents are mixed with the milk. With the MilkoScan™ you can screen incoming raw milk samples to identify a suspect raw milk sample quickly and as a normal part of everyday testing. The suspect sample can then be further analysed to determine the contaminant.



FossConnect™ is a centralised networking management solution CombiFoss™ and BactoScan™ that helps you to reduce operational costs and secure consistent high performance from your analytical instruments. With FossConnect™, you can manage, configure and monitor your instruments remotely from any internet-enabled computer and safeguard your data for whenever you need it.

CombiFoss™ 7 - Making A Difference in Milk Analysis

Foss Analytical

FOSS creates end-to-end solutions that secure and improve food quality. From raw material to finished product. Our analysis instruments refine measurements into information management that enables businesses to run intelligent data-driven productions with less waste and bigger yields. Controlling cost and quality across all sectors and value chains, we help food and agricultural producers limit the number of human errors, scale their business faster and reduce manual labor as well as labor costs. We call it analytics beyond measure.

We cover these food and agricultural industries: Dairy, Feed and Forage, Grain, Flour Milling & Oilseed Processing, Laboratories, Meat, Raw Milk Testing and Wine.

Over the last 60 years, we have made it our business to define the standard of analytical solutions for the food and agricultural industry. We pioneered advanced analysis for the challenging production environments in the 1960’s, and we were the first to integrate chemical composition analysis in process lines. Now our resolve and ambition have also made us the international benchmark in the field of chemometrics and real time analytics.
