Thermal standards in thermogravimetry.
Comparisons of thermogravimetric data from different instruments have often led to controversy because of lack of appreciation that the values are influenced by the apparatus used. Consequently, it is suggested that various compounds be employed as thermal standards for comparing data from different sources. The paper also discusses the variables to be considered when attempting to devise such standards and includes a list of suggested thermal standards covering the ranges 100-400 degrees and 1050-1060 degrees.
