Fast-simple-precision detection

With the rapid development of animal husbandry and the continuous improvement of consumers' requirements for dairy products, the quality and safety of milk have become the focus of people's attention.As one of the most important indicators for evaluating milk quality, the increase in quantity is directly related to the quality of milk and the health of consumers.Therefore, by regularly detecting the number of somatic cells in milk, it can not only protect the quality and safety of milk, protect the health rights of consumers, but also guide the production and management of dairy farms, improve the market competitiveness of dairy products, and promote the animal husbandry industry.sustainable development.

Ampha™ X30 Milk Somatic AnalyzeruseMicrofluidic control technology, electrical impedance technologyandFlow Cytometry, can realize high-throughput, continuous, and non-destructive impedance detection of raw milk somatic cells under the precise reference conditions of microfluidics, and obtain information such as somatic cell viability, quantity, and concentration in real time.No culture, dyeing, simple operation and fast determination, it can greatly improve the detection rate of milk somatic cells. It can be applied to the quality control and product development of various dairy products, improve the evaluation of liquid milk quality and provide prevention and treatment of dairy cow diseases in the pastures.Quantitative scientific data.

How it works

Based on the electrical properties of the cell membrane (membrane capacitance and membrane resistance), different electrical impedance signals will be generated when cells of different sizes and activities flow through a wide frequency (0-30 MHz) alternating current field with the suspension. The concentration of the cell is obtained through analysis., quantity, activity and size information.As shown in the figure below: A) The detection results of cells in alternating current fields at different frequencies: the low-frequency electric field reflects the volume characteristics of the cells, namely the electrical diameter.High-frequency electric fields reflect the dielectric properties of cells, namely cell activity; B) Microfluidic chip; C) Cell electrical impedance signal (blue solid part is the resistance signal, green imaginary part is the capacitive reactance signal), cell membrane integrity determines the capacityThe size of the sexual reactance can be distinguished from the dead cells through imaginary signals, and finally reflected in the impedance phase angle-amplitude scatter plot.
