Abstract
An automatic volatility computer and a method for automatically determining weight changes in substances containing a volatile material. In particular, an apparatus which automatically determines the percentage of volatiles in a substance which contains unknown quantities of polar volatiles such as water or moisture, solvents, plasticizers and the like. The apparatus provides rapid automatic analysis without operator assistance other than the placing of the sample on the automatic balance. The particular improvement in the present invention relates to the ability of the apparatus to project final dry weight without completely drying the test sample utilizing a short heat induction period. This improvement greatly reduces the heat time required and avoids overdrying of the test sample.
