Calculation of dry matter
The successive weighings give us the following information:
- The tare mass: crucible and lid Mt
- The masses for the tare, dry matter and water content of the product: Mws
- The masses for the tare and dry matter: Mds
With this in mind, the % of dry matter in the sample can be determined by the relation:
%DM = (MDS-MT) x 100 / (MWS-MT)
For the quantitative analysis the solute content should always be compared to the dry matter mass of the sample.
