The gold standard in water analysis is still Karl Fischer titration (KF). Yet, this requires solubilization of the water into the methanolic analysis solution. Polymers and solids a bit difficult in this sense. If you can dissolve the polymer or grind it and disperse into a solvent, then the water should be titrable. There are accessories in which the high-shear mixer is built into the titration cell. We bought a regular KF from Mettler-Toledo via its distributor, and that has been working fine. What I did was to melt the polymer, squeeze a drop of it between two glass slides and used the film so produced. Worked fine for me, although it's a bit unorthodox.

Thanks for your answer undoubtedly KF is best instrument. KF is good but I am interested in IR heating type instrument because of ease of handling and its accuracy is comparable to KF. KF needs lots of consumables also so trying to avoid this method.

Hello M'am,

There is a IR based moisture content analyzer commonly used to measure the content in the tablet granules. I used to use a similar but older model when i was in India about 10 years ago. It was from Metler Toledo.

Mettler Toledo Infrared Moisture Analyzer, 0.01 Percent Moisture Content Readability

I hope this helps.

Thanks for the information

Depend of do You need/. If You need very accurate measurements, the cemical analysis is the best (see other answers. But if You need an express-analysis (for example moiture of the wood, corn, etc., etc) You can ask us.

You can take convenient stock of polymer weigh it, put into Microwave oven for drying it sufficiently. Weigh again. Difference of weight is moisture content.

Alternately, professional dielectric dryers are available, which shows indication of total drying status. you can use dryer in place of Microwave oven. (Both are working on same principle but in a microwave oven you have to judge dryness your own
