During the last few years much effort has been expended in attempts to develop apparatus and special techniques for the analysis of small quantities of material. These procedures can be divided into two classes, the micro and the semi-micro. Micro analysis deals with samples up to or about 3-5 milligrams. This micro method consumes much less time, requires smaller quantities of reagents, requires much less of the unknown and in other ways proves superior to macro analysis. However, strict micro analysis often requires the use of a microscope and other delicate pieces of apparatus, as well as a knowledge of chemistry possessed by few of those enrolled in the elementary course of qualitative analysis. It is therefore not applicable to the general course in qualitative analysis.
