Patent ID: 8084756

Claim:
A sensor, comprising: a sensor head having a proximal end and a distal end, the distal end defined by a first planar surface and a second surface tilted substantially 45 degrees away from the first planar surface and toward the proximal end of the sensor head, the sensor head comprising: a light source chamber including an ultraviolet (UV) light source that emits a first UV wavelength; a light source window positioned in the second tilted surface that transmits the first UV wavelength into an analytical area containing a sample having an unknown concentration of a chemical that exhibits fluorescent characteristics; a detector window positioned in the second tilted surface; and a detector chamber including a UV detector that detects fluorescence emissions of the sample at a second UV wavelength transmitted through the detector window; and a controller that calculates the concentration of the chemical in the sample based on the detected fluorescence emission.
