Quantitative semimicro inorganic procedures

Abstract

Representative volumetric, gravimetric, and electrolytic determinations, many on "practical" samples of alloys or minerals, have been applied on a semimicro level. The use of classical microchemical apparatus, which is usually designed to accomodate only a single sample, has been avoided as far as possible. The time-requirements for practical inorganic analyses involving two to six samples of 20 to 60 mg size are usually only two-thirds to one-quarter of the requirement for comparable macro-scale determinations. The precision and accuracy of work at the semi-micro level compare favorably with that expected in conventional pratice.
