Book Description
Excerpt from A Manual for Assayers and Chemists An impression prevails that the results reported by technical analysts are less accurate and reliable than those reported by so-called scientific analysts. This is supposed to be due to the superiority of scientific over technical methods, as well as to a lack of skill in technical analysts. The work of all technical analysts is subject to frequent and careful checking by the slowly working scientific chemists, as well as by technical chemists of the highest skill; consequently all technical errors are certain of discovery and the imperfections in the methods are quickly brought to light. It may be that the general impression is correct, but until the work of scientific chemists is subjected to the same rigid checking the data upon which to base an accurate opinion will always be lacking. The results of the scientists ought to be more accurate than those of the technical analysts, because they are not hurried and can take the time to test, step by step, the perfection of each separation; but after everything has been said, the question of method is of less importance than the care and understanding which each individual analyst may put into his work. Technical methods must be quick, and there is a constantly increasing pressure that they shall give results as near to absolute accuracy as is possible to attain. Whatever improve ments are desirable in these methods must come from the work of technical analysts, working daily, in absolute touch with the varying conditions in widely separated localities.
