PerkinElmer has introduced a cutting-edge Fourier-Transform Infrared Spectroscopy (FT-IR) milk analyzer that features modern optics and user-friendly yet robust software. The LactoScope can thus assess processed, raw and standardized milk, cream, whey and other dairy products.
The analyzer includes the state-of-the-art mid-infrared (MIR) technology for a faster measuring time of 30–45 seconds and a typical accuracy of under 1% CV.
The analyzer’s modular construction reduces the vibration of the FT-IR bench, and its integrated design ensures efficient use of laboratory space. The LactoScope is inexpensive, has minimum downtime and has worldwide support for all its users.

Screening for Melamine in Milk by Lactoscope FTIR
Lactoscope FTIR is a viable technique to analyze the presence of melamine down to a level of 500 ppm or 0.05% m/m. The discrimination limit can be decreased down to 100 ppm (0.01% m/m) using the melamine-specific detection model.

Analysis of the NPN — Calculated Urea in Raw Milk
LactoScope FTIR milk analyzers are used to perform fast routine determination of NPN/Calculated urea in raw milk. The determination of NPN/Calculated urea in raw milk offers a beneficial indication of how effectively cows digest protein in the rumen, thereby offering important information for feeding strategies and reproductive performances.

Determination of the Freezing Point Depression of Milk
The LactoScope technique for predicting the freezing point depression (FPD) of milk is founded on a technique described by J. Koops et al. (1989). The FPD is predicted from the sample conductivity and infrared measurements for the concentrations of protein, fat and lactose of a sample.
