CHEMINI Fe, Iron Analyser

The CHEMINI Fe, CHEmical MINIaturised analyser, is based on flow injection analysis (FIA) with colorimetric detection for the in situ determination of concentrations of Fe(II) and Fe(III). (Vuillemin et al., 2009).

Key Features
  • Fe(II) and Fe(III) determination, ferrozine colorimetric method and dual wavelenght detection, 562nm and 810nm. (Sarradin et al., 2005)
  • In situ periodic calibration
  • Autonomous and cabled capabilities
