26 THE PEAK APRIL 2008 each sample respectively. For sequential analyses, a batch of 12 samples can be analysed in less than 80 min. Application to real prawn samples: Black Tiger Prawns were purchased from a fish market in Osaka, Japan, and used as real prawn samples and analysed using the proposed method. No samples contained detectable concentrations of OTC, CTC and TC. The chromatograms were free from interferences. Conclusions This article describes an inexpensive and simple technique of sample preparation followed by RP-HPLC under 100% aqueous conditions for the simultaneous determination of OTC, CTC, and TC in prawn. The established procedure, which does not harm the environment or humans, has a short analysis time, is extremely inexpensive and provides reproducible recoveries. The procedure is a useful tool for the routine residue monitoring of OTC, CTC, and TC in prawn.
