Abstract: A solid phase extraction (SPE) cartridge for use in a fluorimetric assay comprises an elongate container (10) of a material permeable to fluorescent radiation, having an open inlet end and an open outlet end. For assay of a compound of interest, a solid adsorbent stationary phase (11) is provided in the container to adsorb the target compound from a mobile phase. To reduce background fluorescence that may interfere with the assay, at least one region (12,13) that is is at leastpartially impermeable to fluorescent radiation, for example by absorbence, scattering or refracting, is provided in or on the container wall, suitably on the outlet side and/or the inlet side of the anticipated location of a band or layer (14) of a compound of interest adsorbed in the stationary phase during an SPE procedure.

Abstract: The invention relates to an optoelectronic device for measuring the water content in a plant element (10) and to an apparatus designed to evaluate and monitor in real time the state of hydration of the plant covers (10). It enables measurements to be taken repeatedly at certain time intervals on the same material without damaging or destroying it. The device comprises an optoelectronic probe (1) connected to a measurement module (2), the probe (1) comprising: i) a first light source (3) emitting at a wavelength corresponding to a strong water absorption band; ii) optionally, a second light source (4) emitting at a wavelength close to the first source (3) and weakly absorbed by water; and iii) a photo receiver (5) having a spectral response that corresponds to the emission bands of the first light source (3) or of the first (3) and second (4) light sources, the device including means (16) or modulating the average optical power emitted by the light source or sources (3) at a defined frequency, and means (8) for synchronously detecting the light received by the photoreceiver (5). The probe (1) can be carried on a movable member having two jaws (21, 22) between which the specimen (10) is engaged without being in compressive contact therewith.

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: A miniature readhead for a photometric diagnostic instrument includes a housing of hand-held form factor, configured for receiving reagent sample media therein. The sample media has a plurality of test areas configured to react with, and change color, according to an amount of an analyte in a sample. The holder is sized and shaped for forming an indexed fit with the sample media and includes an array of light sources coupled to the housing, each of the light sources configured to emit light onto a respective one of the test areas. An array of chambers respectively containing an array of light detectors, is configured to enable each of the light detectors to receive diffuse, non-specular reflections of the light from the test areas, while substantially preventing the light detectors from receiving specular reflections of the light.
