A Method of Protein Removal from Body Fluids for the Purpose of Simultaneous Determination of many Constituents.

THE chemical analysis of blood involves the use of some method of protein removal. The necessity arises very frequently in practice to estimate many substances simultaneously in the same sample of blood, which necessitates much time and is very inconvenient if the proteins are to be removed for the determination of each substance. I decided, therefore, to seek an accurate and simple method of removing protein without impairing the analysis of almost all the constituents of blood. The method described here, I believe, answered my purpose and was proved to be applicable for the determination of non-protein nitrogen and chlorides in serum, whole blood, other body fluid and urine. 1.
