Nuclear magnetic resonance studies of the phosphorus(v) pesticides: A rapid determination of the isomer ratio of systox
The integration circuit of the Varian A-60 nuclear magnetic resonance spectrometer is used in conjunction with vapor phase chromatography, to develop a rapid analysis technique for the determination of isomer ratios in technical Systox-Sulfotepp mixtures. The complete analysis requires less than 0.1 g of sample and only 15 min. The isomer ratio in the sample may be determined to an accuracy of ±1.5% and the undamaged sample may be recovered.
