The New LactoScope 500 – Homogenisation
High Pressure Homogenisation
One of the most crucial stages in dairy analysis is sample preparation, and it all starts with homogenisation to ensure a representative and consistent sample.
The LactoScope 500 reduces fat globules to less than one micron and evenly distributes them throughout the sample, This is achieved by the high-pressure, dual stage homogeniser and produces greater accuracy and repeatability by minimising light scattering and spectral distortion.
Unlike instrument workflows that rely on averaging a high number of replicates to produce an accurate result, the LactoScope 500 homogenises before analysis, producing precise results with fewer scans across the spectrometer cell.
Sample Uniformity
A wide variation in the size of fat globules can be present in milk emulsions, even within the same sample aliquot. This results in light scattering, distorting the spectrum. Homogenising the sample achieves uniformity in the size and distribution of fat within the sample, creating clear and consistent light paths.
Analytical Reproducibility
Achieving reliable FT-IR calibrations requires reproducible spectra. If fat particles vary in size the instrument can to “see” different spectra even if the sample composition is unchanged. Variability in the method is reduced when samples are homogenised.
Improved Accuracy
Under or over-reported fat and protein levels can be caused by light scattering from unhomogenised fat particles. More accurate readings of the absorption bands for protein and fat can be achieved by uniformly dispersing fat particles within the sample.
High pressure homogenisation as featured on the LactoScope 500 is the gold standard for FTIR dairy testing, delivering scientific precision and operational efficiency.
