GASOMETRIC DETERMINATION OF METHEMOGLOBIN

Gasometric Determination of Fermentable Sugar in Blood and Urine

Procedures for fermentative determination, in blood and urine, of glucose, or of sugars resembling it in their fermentability by yeast, have been refined by different investigators during the past few years. The chief source of error, undue prolongation of the time of fermentation to one or more days, was removed by Hiller, Linder, and Van Slyke (1925), who utilized conditions under which gluco...

A GASOMETRIC METHOD FOR THE DETERMINATION OF pH IN BLOOD

Gasometric Determination of Hemoglobin by the Carbon Monoxide Capacity Method

The method here described is based on the capacity of hemoglobin to combine with the same maximum volume of CO as of 02. The blood sample, which may vary from 0.1 to 2.0 cc., is saturated with CO in the 50 cc. chamber of the manometric blood gas apparatus of Van Slyke and Neil1 (1, 2). Approximately 2 cc. of carbon monoxide are introduced with the blood, and the chamber is evacuated and shaken....

Gasometric Determination of Oxalic Acid and Calcium, and Its Application to Serum Analysis.* by Donald

is the basis of most of the calcium methods current in biological chemistry, the amount of oxalate in precipitated calcium oxalate being determined by titrimetric measurement of the permanganate utilized. In this paper we present results showing that the oxalate can be determined with equal accuracy by measurement in the Van Slyke-Neil1 (1924) manometric apparatus, and that the gasometric proce...
