The Detection of Impurities by Thermal Analysis
Thermal analysis is used in our laboratory to check material which is intended for use in clinical trials or toxicological studies. Invariably the quality of such samples will be of high purity, 98% or better. This immediately gives some idea of the test which confronts thermal analysis. Generally, we are dealing with samples containing a single impurity of <2% or several impurities of <2%. We feel that DTA has met this challenge with plenty to spare. It has earned its place as one of the techniques employed to evaluate the final purity of material intended for clinical and toxicological use.
