consistency (essential for the analysis of low volatility compounds) of the GC/FT-IR interface. The hydrolysis rate constants obtained from repetitive runs employmg the EC detector have been reported elsewhere [4].

4 Conclusion

A fast and convenient GC method has been developed for a compound [tris(2.3-dibromopropyl)phosphate] that poses a difficult analytical problem for both GC (thermal instability/low volatility) and LC (not amenable to commonly available,
