A DIRECT MICROTITRATION METHOD FOR BLOOD SUGAR

A simple spectrophotometric method for the determination of blood sugar by phenylhydrazine Hydrochlorlde

Improved method for estimating blood sugar.

Received for publication 8 December 1965. reduced copper is oxidized to cupric ions by means of iodine. If no necessary allowance has been made, the cupric ions formed would be completely reduced and precipitated as cuprous iodide in the presence of an excess of soluble iodide in the reagent. Probably to check this reduction by iodide, Harding and Downs (1933) employed potassium oxalate in thei...

A Simplified Bed-Side Blood-Sugar Method

medical profession. But even so, practically all the blood-sugar methods require considerable laboratory facilities and are not suitable for application at the bed-side and in the mofussil. Since the introduction of insulin and the modern developments in the diagnosis and treatment of diabetes, the estimation of blood-sugar has become essential in this disease. The bloodsugar question is, thus,...

A convenient microtitration method for the estimation of amino acids.

This paper presents a convenient micromethod for the estimation of amino acids, based on the reaction with ninhydrin. The ammonia formed in this reaction is determined, after elimination of the interference from ninhydrin with superoxol, by addition of saturated potassium hydroxide, aeration, and titration with standard acid. The application of the reaction with ninhydrin is one of the most spe...

A Simplified Method for Estimation of Sugar in the Blood

(December 1927). That normal blood contains sugar has been known from the time of Claude Bernard, and since then numerous methods have been devised by workers all over the world for estimating its amount, many of these being obsolete now. Formerly, the estimation of sugar in blood used to be a tedious procedure; but nowadays it is a much more simple process. But even so, nearly all the methods ...
