The Colorimetric Determination of Hexosey with Carbazole
The difficulty of applying classical procedures to the qualitative and quantitative determination of carbohydrate in certain biological materials has led to the development of calorimetric methods in which the carbohydrate-containing material is treated with strong mineral acids, causing t,he formation of substances which will react with compounds such as diphenylamine, resorcinol, orcinol, ind...
متن کاملThe Colorimetric Determination of Glucose.
Several new descriptions of colorimetric methods for the determination of blood sugar have been described in recent years (for example, Polis and Sortwell, 1946; Somogyi, 1945; Nelson, 1944; Haslewood and Strookman, 1939). These procedures are all based on the use of alkaline copper reagents and on the production of molybdenum blue by the action of cuprous copper on complex molybdic acid soluti...
متن کاملThe Colorimetric Determination of Hemoglobin.*
The method to be described for the determination of hemoglobin depends upon the comparison, in a calorimeter, of carbon monoxide hemoglobin solutions, one of which has a known hemoglobin content. Hoppe-Seyler (1) was the first to describe carbon monoxide hemoglobin and to make use of this stable combination for estimating the hemoglobin content of blood. He devised a “double pipette” for compar...
متن کاملThe Colorimetric Determination of Blood
In 1926 we (1) published a calorimetric method for the estimation of blood calcium, in which the calcium is precipitated from an alkalinized trichloroacetic acid filtrate as calcium phosphate and determined as phosphate by the Benedict and Theis (2) method for the estimation of inorganic phosphorus. We have since simplified and shortened this method and in this paper we wish to report our impro...
