  • Patent number: 6835351
    Abstract: An optical-chemical sensor which is suitable for the continuous and discontinuous determination by luminescence optics of the concentration of chloride in an aqueous sample and which comprises a luminescence indicator (I) and a polymer (H) carrying the luminescence indicator (I) is characterized in that the luminescence indicator (I) is a non-lipophile acridine or bisacridine compound and the polymer (H) is a linear-chain hydrophile polymer soluble in an organic solvent, whereby it is possible to excite the sensor by commercially available LEDs, to manufacture very large numbers thereof at a moderate cost and in a reproducible way and, preferably, to use it for the determination of physiological chloride concentrations and the sensor furthermore has a wide dynamic measuring range for the determination of chloride; a high sensitivity, stability and reproducibility; a high selectivity for chloride; and a low pH cross-sensitivity.
    Type: Grant
    Filed: January 2, 2003
    Date of Patent: December 28, 2004
    Assignee: F. Hoffmann-La Roche AG
    Inventors: Christian Huber, Tobias Werner, Otto S. Wolfbeis, Douglas E. Bell, Susannah Young
