A chromatographic method based on liquid chromatography (LCJ using column-switching for the determination of ethacrynic acid in urine samples, is described. The proposed system uses an Hypersil ODS-Cl& 30 pm (20 mm x 2.1 mm i.d.) pre-column for the pre-concentration and separation of ethacrynic acid

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,
