Quantitative Microchemistry in Clinical Laboratories

Abstract

Development of quantitative ultramierochemistry for use in the clinical laboratory is discussed, with descriptions of refinements in apparatus and techniques, new reagents, and new procedures.In titrimetric methods refinements are based on the capillary microburet, more sensitive indicators, and use of indicator dyes such as dithizone and dichlorophenolindophenol. In colorimetric methods refinements are based on the microeolorimeter and the photoelectric colorimeter. Precision and reliability have been improved.

Colour Production and Stability in the Folin and Wu Method of Blood Glucose Estimation

“…reacton with no effect upon fading when finally diluted with distilled water and do not consider these methods to be of value. Sobel (1947) uses five times the normal amount of P.M.R. We agree with Tonks in finding such a technique successful.…”

Inorganic Microchemistry

“…Other significant reviews include those by Wyatt (411), Chandelle (57), Sanborn (323), and Reimers (311). Developments in quantitative methods were discussed by Grassner and Abrahamczik (144) and Sobel (343), while work in the field of submicromethods was discussed by Zurcher (430) and Wilson (406). Wyatt-has reviewed the methods of micro filtration (410) while Ingram (174) has reviewed various microchemical techniques, and Belcher has critically reviewed reagents and methods available for the determination of potassium (25).…”
