Abstract
Summary: The automated method for the determination of trimethylamine (TMA) in fish and shrimp extracts, which is based upon the colour change of an indicator solution into which TMA vapours are injected, was further improved. Methods for the automated determination of dimethylamine (DMA) and ammonia in extracts were developed and elaborated. the accuracy and precision of the automated TMA and DMA determination equal those of the gas chromatographic determination of these amines described previously.Both TMA and DMA can be analysed at a speed of thirty samples in an hour, whereas the rate of analysis for NH3 is sixty per hour.This publication has 5 references indexed in Scilit:
