The dry weight or dry matter is that part of a substance that remains after deducting the mass of water contained:
In it are
- The mass of dry matter
- The total mass of the sample
- The mass of water.
Based on the total mass gives:
That is, Dry matter content and water content add up to 100 percent, with
- (Mass fraction of Trockenbsubstanz )
- (Mass fraction of water ( water content) ).
The dry matter content is used in various fields:
- In the waste management technology, especially in bio-waste and residual waste, the TS is often used in addition to the fresh mass as design and size as a criterion for landfilling
- In the timber for the wood moisture (even in a different definition)
- For cheese, the proportion of dry matter is specified differently for the consumer, depending on the cheese Group: The fat content of hard cheeses is specified in the trade usually in percent fat in dry matter ( FDM )..
- In contrast, in soft cheese of magnitude lower absolute content (based on dry mass ) is often called.
