Computerized technique in organic microelemental analysis III. Automatic determination of fluorine in organic compounds

Abstract

The automatic and computerized rapid microanalytical determination of fluorine in organic and organometallic compounds is an easily reproducible procedure. The procedure consists of the combustion of the compound in an empty tube; transfer of the combustion products to the titration vessel by automatic wash; and, finally, colorostatic titration of HF with Th(ClO 4), against alizarin red S. The entire analysis and preparation of the equipment for the next determination are programmed in the 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 disk for further processing.
