N2 - A fiber optic sensor array for the time-resolved, laser-induced fluorimetric detection of heavy metals is presented. Design considerations and a performance evaluation for the laser module, based on a pulsed nitrogen laser, and the detector module, based on an intensified gated charge transfer device (CCD) camera, are given. For preliminary investigations a simple probe with a 30 m fiber bundle connected to seven 'bare-fiber' sensors has been constructed. Seven commercially available chelators were employed: Indo-1, Fura-2, BTC, Quin-2, 8-hydroxyquinoline-5-sulfonic acid (HQS), Calcein and Calcein Blue. A matrix formalism for a simple image analysis and multivariate calibration (PLS2) was developed and tested for the determination of mixtures with Zn, Cd, Cu and Ni.
