Observations on the Use of the Flame Photometer for Analyses of Blood* by F. R. Hunter with Tee Technical Assistance of Gladys Dart Berenda

Barnes et al. (1) described a flame photometer and various authors have since analyzed the sources of errors in the technique and made various suggestions for eliminating them (2-12). These investigators have been primarily concerned with the design and operation of the instrument, the interference of one substance with another, and similar problems. The purpose of the present investigation was to determine the most accurate and most convenient method of preparing blood for flame photometric analyses of Na and K and to demonstrate what corrections should be applied to compensate for errors introduced in preparing the blood.
