Simultaneous TG, DTA and EGA technique for the determination of carbonate, sulphate, pyrite and organic material in minerals, soild and rocks. IV: Reproducibility and accuracy of the determination of sulphur trioxide and carbon dioxide

A simultaneons TG, DTG, DTA and EGA techniqne is described for the determination of sulphate, carbonate, pyrite and organic material in minerals, rocks and soils. Results are reported of many parallel measurements on CnSO 4 .5H 2 O and KHCO 3 as standards in order to determine the reproducibility and error of the method. The method was found to be suitable for the given purpose
