A completely new approach in irradiation as well as design to achieve a new methodology in flow injection analysis . This include the use of a powerful 2000mW (450nm) solid state laser beam to irradiate a moving plug sample of analyte material via a semi automated methodology . The measurement can be done at 0-1800 i.e.; attenuation of the incident beam of light or via 0-900 diversion of the incident beam of light whether it is fluorescence or reflection or reflection of dispersed light . Time adjustment in seconds can be managed with a time laps duration of 0-90 seconds. Improved S/N was achieved via low frequency electronic filter RC. Alarm signal and push buttons switch can manage with high reliability irradiation and successive repeatable measurements and timing. Response output can be recorded digitally or by X-t potentiometric recorder (single pen or two synchronized pen or both modes).
