[Study of a new kind of spectrometer coupled with flow injection and CCD diode array detection for multi-components simultaneous determination].
A new kind of spectrophotometric instrument combined with a flow injection device, a prism spectrography, a CCD diode array detection system and a popular microcomputer was established for multi-components simultaneous determination. The measurements of lead and cadmuium with meso-tetra (4-trimethylammoniumphenyl) porphine were completed with the instrument. The detection limit was 0.014 microg/mL for Pb(II) and 0.015 microg/mL for Cd(II). The sampling rate was 60 samples/h.
