    Abstract: A gas sensor comprises a cavity for containing a gas, means 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 for detecting radiation which has passed through the cavity. The walls of the cavity are sufficiently reflective to the radiation that the cavity is substantially uniformally illuminated with the radiation.

    Abstract: A multichannel fluorosensor includes an optical module and an electronic module combined in a watertight housing with an underwater connector. The fluorosensor has an integral calibrator for periodical sensitivity validation of the fluorosensor. The optical module has one or several excitation channels and one or several emission channels that use a mutual focusing system. To increase efficiency, the excitation and emission channels each have a micro-collimator made with one or more ball lenses. Each excitation channel has a light emitting diode and an optical filter. Each emission channel has a photodiode with a preamplifier and an optical filter. The electronic module connects directly to the optical module and includes a lock-in amplifier, a power supply and a controller with an A/D converter and a connector. The calibrator provides a response proportional to the excitation intensity, and matches with spectral parameter of fluorescence for the analyzed fluorescent substance.

    Abstract: A liquid and gas analyzing system that provides a sample collecting probe that delivers the sample through inert materials to prevent any contamination. For gas analyzing for environmental monitoring process control, a sample collecting probe having a borosilicate glass tube liner connected through an inner spiral tube to the analyzer prevents contamination. The system then delivers the sample to a single pass radiated optical cell by a light beam. The light beam is collected by a miniature CCD array spectrometer and delivered to an industrial PC. The output from the industrial PC is then delivered to a software controlled data acquisition system for analysis. The system is constructed to be a modular in design allowing addition of complementary components for measuring and analyzing different materials. The system described can be used for extractive gas analysis as well as extractive liquid analysis for monitoring stack gases, environmental air or general environmental monitoring and with modifications for breath analysis and human saliva and blood testing. The system is also adaptable for long path remote sense gas monitoring of fence lines and for leak detection.

    Abstract: Disclosed is an integrated, multi-module luminescence measuring system. The system can selectively conduct lifetime decay or steady-state measurements of light emitted by a sample which receives exitation light. The system includes: a sample chamber which directs monochromatized, focused excitation light from a selected source at a selected sample and directs any resultant emitted light through a monochromator to either a first gated photodetector or a second regular photodetector. Also present is a reference module with a regular photodetector which may selectively receive a portion of the excitation light. A lifetime decay detector module pulses a selected light source and the gated photodetector so that a converter produces digital signals related to output signals from the photodetector, the digital signals representing the integral of the intensity of the emitted light over a selected time. A steady-state detector module pulses a selected light source and includes a resettable integrator-A/D converter combination which receives the output from the regular photodetectors and produces digital signals representing the integrals over varying time intervals of such outputs. The integrator is reset and the A/D convertor is turned on whenever the light source is pulsed. A data processing module controls sample selection, the wavelengths of the excitation and emitted lights, light source selection, the number and time-width of the various integrations, and the storage and processing of the resulting digital signals.
