Computerized technique in organic microelemental analysis: Part II. Automatic determination of sulfur in organic compounds

Described is the automatic and computerized rapid microanalytical determination of sulfur in organic and organometallic compounds. The procedure consists of the combustion of the compound in an empty tube, transfer of combustion products to the titration vessel by automatic wash, and, finally, colorostatic titration of sulfuric acid with Ba(ClO₄)₂ against dimethylsulfonazo III.The entire analysis and preparation of the equipment for the next determination are programmed in time of the 6-min cycle.The analyzer is interfaced to the departmental real-time time-sharing computer, along with electronic microbalances and other analyzers, as a part of the microanalytical laboratory computer service.Results of the analyses are reported on CR terminals and are also stored on the magnetic disc for further processing.
