Calibration and Control of your FTIR Analyser – Improve Dairy Efficiency

After making a significant investment in a FTIR milk analyser to rapidly test dairy products and generate reliable results, it is important to maintain the accuracy using Calibration and Control samples.

Three main factors influence the robustness of the calibration line.

  • Analyser performance
  • Calibration sample range
  • Calibration sample Uncertainty of Measurement

Analyser performance is down to your choice of manufacturer. However, we can and do supply Calibration samples with the widest component ranges with the lowest Uncertainty of Measurement.

Our samples are supplied by QLIP Netherlands, Qlip performs over 200,000 Rose Gottlieb (fat) and Kjeldahl (protein) analyses, 90 percent of which are carried out in duplicate. These duplicate analyses are used by Qlip to calculate the Uncertainty of Measurement of the Calibration Material, currently +/- 0.01% for fat and protein.

For example, the Raw Milk Calibration Samples have Ranges of 0-6% for fat and 0-5% for protein and Lactose. The combination of these ranges with the low Uncertainty of Measurements guarantees you a robust and reliable calibration line.

For a dairy processor, which process monthly over 31 million kgs of raw milk, an improvement of 0,01% accuracy for testing protein will save monthly a value of £18,750 on protein and £9,375 onfat! The financial impact on your production process of an accurate calibration of your instrument is immense!
