The determination of blood glutathione by amperometric titration.
In 1946 Kolthoff and Harris devised a method of titrating mercaptans in aqueous alcoholic solution with silver nitrate. They used a rotating platinum electrode with suitable current measuring equipment to locate the titration end-point. Benesch and Benesch (1948) applied this technique to the determination of sulphydryl groups in serum protein, and Weissman, Schoenbach, and Armistead (1950) use...
متن کاملAmperometric Titration Largely Overestimates Chloride Concentrations in Chloroplast Extracts
D eterm ination of chloride con ten ts in aqueously isolated chloroplasts from spinach by am perom etric titration indicated chloride concentrations of 60 to 100 m m ol l_l (based on a chloro plast volume of 25 (a.1 m g^1 chlorophyll). H ow ever, when analyzed by anion chrom atography, chloride contents in chloroplasts w ere much lower (1 — 8 mmol I 1). In leaf extracts chloride concentra ti...
متن کاملAmperometric titration of disulfide and sulfhydryl in proteins in 8 M urea.
Of the numerous methods which have been used in the estimation of disulfide bonds and sulfhydryl groups in proteins and amino acids (l), the amperometric, argentimetric titration procedure, with appropriate modifications, is especially well suited for this purpose. This paper describes a modification and extension of known methods whereby these groups may be titrated in 8 M urea. The total numb...
متن کاملAmperometric Enzyme-based Gas Sensor for Formaldehyde: Impact of Possible Interferences
In this work, cross-sensitivities and environmental influences on the sensitivityand the functionality of an enzyme-based amperometric sensor system for the directdetection of formaldehyde from the gas phase are studied. The sensor shows a linearresponse curve for formaldehyde in the tested range (0 - 15 vppm) with a sensitivity of1.9 μA/ppm and a detection limit of about 130 ppb. Cross-sensiti...
متن کاملNote on the formaldehyde titration of milk-protein, and its application to the estimation of caseinogen.
THE writer described in this Journal [1932] an improved technique for the determination of milk-proteins by formaldehyde titration. Very satisfactory results were obtained for mixed milks using a factor, 1 cc. N NaOH = 1-74 g. milk-protein, which however for milks of individual cows showed a somewhat wide variation, ranging from 1-63 to 1F87. It was tentatively suggested that this might arise f...
