Abstract:A low inner volume (ca. 64 ml) probe was built up in an injectorcommutator in order to behave as a photometric leaping detector in ow analysis. It comprises a bicolour lig ht-emitting diode (BLED ), as a source of pulsed radiation in the red and green visible region, and two phototransistors as transducers. Sample injection, detector relocation, analytical signal recording, data treatment and de nition of the spectral working range were computer-controlled. T he feasibility of the system was initially demonstr… Show more
