    Abstract: A gas sensor comprises a cavity (32) for containing a gas, means (16) for generating radiation which is transmitted through the cavity and includes one or more wavelengths which is absorbed in use by a gas to be detected; and a detector (14) for detecting radiation which has passed through the cavity (32). The walls of the cavity (32) are sufficiently reflective to the radiation that the cavity (32) is substantially uniformally illuminated with the radiation.

    Abstract: Described and claimed is an interchangeable tip-open cell fluorometer comprising a housing and a fluorometric probe tip interchangeably connected to the housing, the probe tip including a probe tip housing defining an open cell and enclosing a probe optical arrangement, the probe optical arrangement including an excitation source and a fluorescence detector wherein the excitation source is aimed directly into the fluorescence detector such that a sample can be fluorometrically detected. Also claimed is a method of using this interchangeable tip-open cell fluorometer for detecting fluorescent signals emitted by one or more fluorophores from samples from a natural or industrial water system. The fluorometer, when coupled with a controller, is capable of monitoring and optionally controlling an industrial process or system.

    Abstract: The invention relates to an arrangement for continuous determination of a substance comprising a chemically reacting sensor element (21) arranged in or adjacent to a limiting wall of a volume (22) containing the substance, where in a housing (2) of a modular device (1) optical elements to read the sensor element (21) are arranged, comprising at least one light source (35) illuminating the sensor element (21) and at least one sample detector (29) detecting the light scattered by the sensor element (21), and where a front side of the housing (2) comprises a coupling for the sensor element (21), so that the sensor element (21) may be interchangeably and modularly coupled to the front side of the housing (2). A glass body (24) is arranged adjacent to the coupling for direct contact with the sensor element (21) and separate conduits (34, 31) for the illuminating and for the scattered light are arranged rearward of the glass body (24). The modular device (1) allows for easily interchanging the modular sensor element (21) and provides an optical connection between the sensor element (21) and the detector (29) which is steady and allows for high quality measurements.

    Abstract: The invention relates to a system for the spectrometric determination of a chemical and/or physical process variable of a measuring medium (29), comprising a process probe (2; 3, 4, 5, 6), a spectrometric module (9; 10, 11, 12, 13) and an evaluation module (19), whereby various process probes (2; 3, 4, 5, 6) can be used together with the system. The respective process probe (2; 3, 4, 5, 6) used is associated with a probe-specific spectrometric module (9; 10, 11, 12, 13) matched for the respective process probe (2; 3, 4, 5, 6). The probe-specific spectrometric module (9; 10, 11, 12, 13) is adapted to provide spectral measuring signals from which the evaluation module (19) determines the process variable by means of a substantially uniform evaluation algorithm.
