The application of flame photometry to sodium and potassium determinations in biological fluids.
The need for a rapid, accurate method to determine quantitatively Na and K present together in biological fluids has been met by the procedures to be described. The necessity of separating these elements prior to their determination by the various chemical methods usually employed has led to procedures which are often prohibitively tedious and time-consuming. The recent development of flame pho...
متن کاملThe determination of calcium in biological fluids by flame photometry.
The use of flame photometers has greatly simplified and expedited the estimation of sodium and potassium. Calcium is one of the elements which it is possible to determine by flame photometry, but little advantage has been taken of this fact in biological work for a number of reasons. The concentration of calcium in extracellular fluids is usually less than that of potassium ; a given quantity o...
متن کاملContinuous-recording flame photometry of sodium and potassium in serum.
Serum sodium and potassium analyses by continuous-flow flame photometry is a well-accepted procedure (1, 2). Recently Habig and Williamson (3) have used the widely available Instrumentation Laboratory Model 143 (IL-143) flame photometer for continuousflow analyses. Pennacchia et al. (4) have operated this flame photometer at rates as high as 120 samples per hour. In both systems the results app...
متن کاملSemimicro flame photometry of serum sodium and potassium.
BE PIONEER WORK of Lundegardh (1) established flame photometry as an analytical technic, but widespread interest was not aroused until 1945, when Barnes et al. (2) described a simple instrument which was much faster and at least as accurate as existing chemical methods for the determination of certain metals. A dormant clinical interest in the measurement of serum sodium and potassium was there...
متن کاملPotentiometric analysis for sodium and potassium in biological fluids.
Results obtained with a potentiometric analyzer, NOVA 1, specific for sodium and potassium, were compared with those by flame photometry. Both instruments showed linearity within a physiological range of sodium and potassium concentrations and had similar precisions. Volume displacements from addition of albumin or Intralipid to aqueous samples yielded the predicted lower flame-photometric resu...
