Determination of the Total Sulphur Content in Gas Oils with a Flame Photometric Detector

During a study of catalytic hydrodesulphurization of gas oils’ a method was needed not only for the determination of the distribution of sulphur compounds, but also, more importantly, for the determination of total suIphur content. Methods have been published for the determination of the distribution of sulpbur compounds in gas oils using gas chromatography (GC) with a coulometric detector’>3. ...

Simplified determination of serum iron and total iron-binding capacity.

2,4,6-Tripyridyl-s-triazine (TPTZ) is a color reagent for ferrous ion in the pH range 2 to 10,when ascorbic acid is used as the reducing agent. In this range TPTZ and ferrous ion combine in the ratio of two to one. Tris buffer is commonly used to maintain an alkaline pH, but it reacts with other reducing agents, rendering them ineffective. These observations suggested a method for the joint det...
