New product announcement: Bruker introduces MPA II Dairy Analyzer for its integrated FT-NIR milk and dairy analysis solution

On 15 November 2021, Bruker announced the launch of the liquid sampling module (LSM II) – a reliable, fast, and cost-effective solution for the quality control (QC) of milk and liquid dairy products as well as plantbased alternatives. It is now an integrated part of the Multi Purpose Analyzer (MPA II) Fourier Transform Near-Infrared (FT-NIR) spectrometer and together they form the new “MPA II Dairy Analyzer” (Figure 1). Being capable of analyzing both liquid and solid samples, the system sets a new standard in routine QC for milk and dairy product analysis. NIR spectroscopy is an acknowledged method for all sample types described in the updated ISO 21543 IDF 201 guidelines released in 2020. Suitable for raw, processed, or standardized milk, whey, cream, concentrates and other milk products, such as ice cream, yoghurt, cheese, and dairy powders such as whey powder and infant formula, any sample form can be analyzed in seconds in the lab or at-line near production. Thanks to the MPA II Dairy Analyzer, more frequent testing will result in tighter control, allowing manufacturers to adhere to regulations and, ultimately, achieve direct cost savings. The upgraded dual-concept LSM II allows software-controlled switching of the sample feed – depending on the product and its viscosity. Raw milk is fed into the high-pressure homogenizer whereas all other products are simply pumped into the flow cell, providing an increased homogenizer lifetime. In contrast to the conventional FT-IR analyzers, even viscous dairy products such as yogurt drinks and ice cream premixes and products with particles can be analyzed thanks to the measuring cell’s large layer thickness of 1mm (1000 lm). The flow cell is made of quartz glass and is stable for years without any cuvette wear, eliminating any need for frequent slope and bias correction or Figure 1.
