DEVICES HAVING AN INTEGRATED COMPUTATIONAL ELEMENT AND A PROXIMAL INTERFERENT MONITOR AND METHODS FOR DETERMINING A CHARACTERISTIC OF A SAMPLE THEREWITH
摘要
The output of optical computing devices containing an integrated computational element (212) can be corrected when an interferent substance or condition is present. The devices may comprise an optional electromagnetic radiation source (200); a sample detection unit comprising an integrated computational element (212) and a detector (216) configured to receive electromagnetic radiation that has optically interacted with the integrated computational element and produce a sample signal associated therewith; an interferent monitor (222) located proximal to the sample detection unit, the interferent monitor being configured to produce an interferent signal associated with an interferent substance; and a signal processing unit (220) operable to convert the interferent signal into an interferent input form suitable for being computationally combined with the sample signal, the signal processing unit being further operable to computationally combine the sample signal and the interferent input form to determine a characteristic of a sample in real-time or near real-time.
