One of the common methods used for the determination of concentrations is Flow injrction analysis for which expensive and sophisticated instruments are essential. If such an instrument is constructed at our affordable price, it is helpful to be used in common laboratories, especially in third world countries` like Sri Lanka. with this view in mind I have taken ideas published in the literatute in several places and combined them to developan efficient Flow Injection Analyser that can be constructed for a reasonable price. It should be noted that all parts of thas FIA are available in the local market. Main parts of this instrument are reagent rese rvoir, injection port, mixing coil and the detector. This detector consists of log converter, power supply unit, cell compartment digital readout device and the detector compartment to avoid variation of digital output, it was needed to connect a simple chartrecorder to the instrument. This construction can be applied in cases where concentrations in solution are determined in trace....en-USUniversity of Colombo, UC(SCI): Sri Lanka HELLIS NetworkChemistry, analyticalFlow Injection AnalysisFlow Injection Analysis-economicsThesis
