Guarding Against the Next Melamine
The DairyGuard™ Milk Powder Analyzer provides non-targeted screening of adulteration to ensure the quality of your milk powder products. This system helps you deliver your most important ingredient by far: peace of mind.
The DairyGuard can accommodate various sized petri dishes for easy measurement in any lab environment. We’ve also designed the system with full self-checking and diagnostics to ensure it is always performing at the highest capacity, and optimized for the most dependable results. See the configurations table below for available options for the system.
The DairyGuard Milk Powder Analyzer system features:
IR Ready for Any Challenge
The enhanced Frontier™ FT-NIR spectrometer features:
For the DairyGuard system, the Frontier can be optionally configured as a dual range, MIR/NIR platform to expand the breadth of your analyses and allow for effortless transition between transmission, reflectance, and transflectance modes, and measurement of other ingredients.
Setting the Standard
The Frontier is loaded with a range of advanced innovations designed to provide optimal performance from the configuration you choose.
The DairyGuard Touch Apps software includes built-in methods and advanced algorithms developed by PerkinElmer scientists to screen for known and unknown economic adulterants in milk powder, as well as performing the same fast measurements routinely used for protein, moisture, and fat monitoring. This non-targeted safety testing allows for quick, simple, on-the-spot screening of samples. For specialized industries requiring a custom set of protocols, the DairyGuard Method Development Service is available to help guide you through the development process.
The Spectrum 10 software suite drives the Frontier NIR system and can support advanced FT-NIR analysis in research and industrial laboratories, always providing optimal results. The software supplied with your instrument enables you to control the instrument and to manipulate the spectra that you collect. The spectrometers can operate in ratio, single-beam, or interferogram mode.
With the Spectrum Workflow Developer software package, Spectrum 10 software is included, along with the revolutionary Spectrum Adulterant Screen for identifying contaminants, Spectrum Quant for incorporating algorithms for quantitative measurements, and Spectrum Touch Developer for creating customized Touch Apps for specialized, simplified workflows.

The value of milk powder is linked to its protein content, and standard methods for protein analysis rely on a simple nitrogen assay, with the protein concentration inferred from the nitrogen content. Consequently, the addition of chemicals rich in nitrogen can artificially increase the apparent protein and thus the price demanded. NIR spectroscopy clearly has a role to play, given its ubiquity in raw materials testing. The unique Adulterant Screen algorithm from PerkinElmer retains the strengths of non-targeted chemometric methods like SIMCA, but obtains greater sensitivity by utilizing a library of spectra of potential adulterants. The method can be easily adapted to screen new products or for new adulterants, without having to prepare mixture samples for calibration.
