Metrology of Water Content Measurements in Practice
– Optimization of the Sample Drying Process
Using a Moisture Analyzer

Join us for a 1-day training course, during which we will define the factors that affect the time and accuracy of analysis, taking into account the structure of the sample under study. The training combines theory and practice.


  • 10:00 Warm-up

    1. Introduction: water as an important quality factor of chemical and food products.
    2. Normative and non-normative methods of water content testing – important differences.
    3. Systematic and random error of the method used in water content testing.
    4. Construction and operating principle of the moisture analyzer – IR radiation in water content testing.
    5. Adjustment of the moisture analyzer for mass and temperature measurements.
    6. Optimization of the drying process in terms of accuracy and analysis time.
        a. Drying profiles as differentiated methods of heat delivery to the product.
        b. Influence of parameters defining dry weight stability on analysis result.
        (criterion for ending the analysis)
    7. Types and methods of preparing samples for analysis.
        a. Structure of the sample during the drying process.
        b. Storage, collection and homogenization of samples.
        c. Sample mass size in the drying process.
    8. Validation of the method and the moisture analyzer – general principles.
    9. Detection methods and evaluation of the influence of the basic error of the moisture analyzer for water content/ dry mass measurements on the result of the analysis of real samples.
    10. Testing.
        a. Analysis of precision and validity of drying results for samples of powder structure, semi-liquid samples and solid samples.
    11. SOP for periodic verification of the proper operation of the moisture analyzers.
    12. Summary

    Slawomir Janas, PhD

    for more than 25 years has been responsible for weight measurements and measurement methods at RADWAG. He is the author of more than 20 guides and scientific papers on topics related to mass measurements and methods used in water content studies. In 2019, he received a PhD in the discipline of commodity science from the Radom University of Technology and Humanities. He is also in charge of cooperation with notified bodies in the field of certification of balances and weighing systems. He is an expert in metrology of mass measurement, moisture measurement and validation of measurement devices and methods.
