The chiral separation of VX isomers was achieved using normal phase liquid chromatography with a Chiracel OD-H colrnnn. The separation of the enantiomers of VX was first described by Kientz et al. (1994). They used a thermo-ionic detector for the selective detection of phosphorus compoimds. Unfortunately, this technique was not robust enough. The same separation was also described by van der Schans et al. (2()03) using electrochemical detection. The mobile phase (hexaneiethanol 95 5) was mixed after the column procedure with 0.1 M lithimn perchlorate solution to ensure conductivity necessary for electrochemical detection. The system could be used to study the stereo-selective degradation of VX in in vitro samples such as liver homogenates and plasma. Although the electrochemical detection was...
