Colorimetric determination of potassium by Folin-Ciocalteu phenol reagent.
A method for the colorimetric estimation of manganese by reduction of the phosphomolybdicphosphotungstic acid phenol reagent has been described (Abul-Fadl, 1948). Cobalt was also found to give a similar colour reaction in the presence (but not in the absence) of amino-acids. Conversion of cobalt into the cobaltinitrite did not affect its response to this reaction. As methods for the estimation ...
متن کاملA modified orcinol reaction for RNA determination.
A MONG the various colorimetric methods for RNA estimation, the orcinol reaction of Mejbaum as modified by Schneider (1) remains the most sensitive and commonly employed technic for purine-bound ribose quantitation. Later attempts that were made to estimate pyrimidine nucleotides and nucleosides (2, 3) have also been based on the color reaction of ribose with orcinol and ferric chloride, which ...
متن کاملColorimetric Determination of Serum
In the past few years there has been renewed interest in the study of serum cholinesterase in various disease states, particularly those affecting the liver. Recently, a colorimetric method for the determination of this enzyme in the serum was reported by Ravin, Tsou, and Seligman (1). Their method, simple to perform, is as accurate as the gastrometric technique and more specific than the elect...
متن کاملAn Improved Method for the Simple and Accurate Colorimetric Determination of Urea with Ehrlich's Reagent.
An improved method for the colorimetric determination of urea is described. The method is simple, requiring a deproteinized filtrate obtained after treatment of a small quantity of whole oxalated blood, serum, plasma or urine with 12.5% trichloracetic acid containing 50 g. activated carbon. The addition of Ehrlich's reagent to this filtrate results in the immediate production of a stable yellow...
متن کاملColorimetric determination of potassium in plasma and serum by reflectance photometry with a dry-chemistry reagent.
We evaluated a colorimetric assay of potassium in plasma and serum with the Boehringer Mannheim Reflotron reflectance photometric analyzer, which is designed for near-patient testing in hospitals and physicians' offices. This potassium method does not require calibration or instrument maintenance by the operator. Analysis of 30 microL of plasma or serum takes approximately 140 s. Within-day imp...
