Fundamentals of Moisture Measurement

Moisture content influences the physical properties of both natural and man-made products.  Concentration, purity, microbiological stability, flow, nutritional value, and legal conformity are just a few of the characteristics affected among many others.  Join us for an in-depth exploration of several key quantitative methods of moisture content determination including loss-on-drying (LOD), chemical (Karl Fischer titration), and thermo-gravimetric (TGA) techniques.  Learn the essentials - and more!  Explore the advantages and disadvantages of each technique's suitability to your needs and sample characteristics.  Discuss problem samples.  Learn to differentiate and separate measurement of water from volatiles, oils and other "moisture" in your samples.  You'll gain insight into practical approaches, troubleshooting, solutions, and much more that you can implement to improve productivity, analyses, and results in the lab.

These and many more insights, discoveries, along with expert instruction, await both experienced and new lab personnel alike!
