Continuous-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 کاملSimultaneous Determination of Sodium and Potassium in Small Volumes of Fluid by Flame Photometry
INTRODUCTION In two earlier papers (Ramsay, 1950; Ramsay, Falloon & Machin, 1951) a method was described by which it was possible to determine the concentration of sodium in samples of fluid of the order of io~ cu.mm. in volume. This method has now been extended to include the determination of potassium simultaneously upon the same sample. It is still in the experimental stage of development; w...
متن کاملThe 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 کاملAn Automatic Flow-Batch Standard-Addition Method for Sodium Determination in Alcohol Fuel by Flame Photometry
A agência brasileira que regulamenta a produção e comercialização de álcool combustível estabelece que a concentração de sódio deve ser determinada usando a fotometria de chama e curva analítica construída com soluções padrão preparadas em uma matriz que se assemelhe às amostras. Todavia, essa metodologia pode produzir resultados inexatos porque o álcool combustível apresenta uma variabilidade ...
