CM-Method and Kiln Drying compared
The CM-Method and kiln drying are being played out against each other. Justified? No, because the CM-Method measures the free water content and kiln drying the evaporable water. That’s how both Methods can be combined and can reach the same results. Read more
Maximal Precision with the CM-Method
The CM-Method (Carbide-Moisture-Method) is one of the fastest and most reliable measuring methods for identifying/finding water in liquid or granular materials. This method is over 100 years old and was scientifically mentioned for the first time in June 1905 (Society of Public Analysts). P.V. Dupré was the Author of this publication and explained its works in the following: Calcium carbide reacts with the water of a sample, which previously had been weighed out, to create acetylene and calcium hydroxide. As acetylene is gaseous, the rising pressure in a closed system allows us to determine the amount of water in a sample quite precisely (thousandth range). Read more
