Abstract

To appreciate this book properly it is necessary to understand what is meant by ultramicroanalysis. This is easily achieved by citing the weights of samples used in some of the better known analytic methods. Macro-methods employ samples of the order of 0.1 Gm.; semimicro-methods require samples of 10 to 20 mg., and micro-methods use samples of about 1 mg. The ultramicro-method employs a sample of 0.001 mg. The value of a technic which permits the use of samples of ultramicro proportions is evident to the biochemist, clinician and biologic research worker. It is interesting to note that most of the fundamental chemistry of plutonium was elucidated by the use of the ultramicro-method before as much as a milligram of the element was synthesized.

To anyone employing or planning to employ the ultramicromethod, Professor Kirk's book will save a great deal of time and effort. The methods in the literature have
