Apparatus and method for determining weight loss of a heated material

摘要

The present invention provides a method and apparatus for accurately determining weight loss of a sample during heating in a furnace. The method includes the steps of placing a sample in a heated furnace, heating the sample while measurements of sample weight are made, determining rate function from the sample weight measurements, producing a weight loss correction factor using the rate function and using the weight loss correction factor to obtain a corrected weight loss for the sample.
