Abstract: A method for quantifying a crude oil in water is provided. The method includes selecting an ultraviolet/visible (UV/Vis) wavelength to perform a measurement, preparing calibration solutions in xylene, and preparing a calibration curve from the calibration solutions. A sample is prepared including extracting the crude oil from the water in a two-phase separation with xylene. An absorbance of the sample in the xylene is measured at the UV/Vis wavelength. A concentration of the crude oil in the water is calculated from the absorbance.

Abstract: Described are systems and techniques directed to optical inspection of moving products (wafers, substrates, films, patterns) that are being transported to or from processing chambers in device manufacturing systems. Implementations include a system that has a first source of light to direct a first light to a first location on a surface of a product. The first light generates, at the first location, a first reflected light. The system further includes a first optical sensor to generate a first data representative of a first reflected light, and a processing device, in communication with the first optical sensor to determine, using the first data, a property of the product.

Abstract: A gas sensing system measures a concentration of first and second gasses in a gas sample disposed in a cavity containing a porous scattering material. The first and second gas each have an absorption peak at a different wavelength. First and second emitters emit light having a spectrum that includes one of the different wavelengths. A single sensor, or multiple sensors, detect at least some of the light emitted by the first and second emitters. A processor determines concentration of the first and second gases from signals from the sensor that indicate intensities of the light from the first and second emitters. When a single sensor is used, the first and second emitters are driven, and the sensor signal detected, at different times. When multiple sensors are used, the sensors detect signals at one of the absorption peaks.

Abstract: Provided are an analysis device, an analysis method, and the like that predict a concentration even for a sample having high concentration that can be outside a measurement range as it is, using an absorbance measurement result in a reaction course at the time of measurement of a test liquid containing an immunological reagent and the sample, and determine an optimum dilution rate to conduct measurement. As the present invention, for example, an analysis device having means (A) that detects a prozone during measurement of a sample, and means (B) that determines a high concentration region by automatically determining a dilution rate of the test liquid can be recited.

Abstract: A reference body 1 includes: a support 10 provided with a first light passing portion 18, a second light passing portion 19, a first accommodating space 14, and a second accommodating space 15; a first fluorescent body 20 accommodated in the first accommodating space 14 and configured to emit first fluorescence in a second wavelength band when irradiated with first excitation light in a first wavelength band through the first light passing portion 18; a second fluorescent body 30 accommodated in the second accommodating space 15 and configured to emit second fluorescence in the second wavelength band when irradiated with second excitation light in the first wavelength band through the second light passing portion 19; and a light shielding portion 13 disposed between the first accommodating space 14 and the second accommodating space 15. In a case where a light amount of the first excitation light incident on the first light passing portion 18 and a light amount of the second excitation light incident on the second light passing portion 19 are equal to each other, a light amount of the first fluorescence emitted from the first light passing portion 18 and a light amount of the second fluorescence emitted from the second light passing portion 19 are different from each other.

Abstract: Methods and systems for detecting foreign material within a product stream in real-time, involve illuminating a portion of the agricultural product stream with light spanning a wavelength range including or within near-infrared and/or shortwave infrared wavelengths; scanning a line of the illuminated agricultural product stream to acquire a hyperspectral image of the line, the hyperspectral image of the line having a width of a single pixel; processing the hyperspectral image of the scanned line to obtain spectrum data for one or more pixels of the hyperspectral image of the scanned line; comparing the obtained spectrum data of the one or more pixels to predetermined spectrum data to determine whether the obtained spectrum data is indicative of foreign material within the scanned line of the agricultural product stream.

Abstract: One or more techniques and/or systems are provided for waste object detection. For example, a waste alert component is configured to emit ultraviolet light towards a waste detection zone, such as a bathroom floor or countertop. If a waste object, such as a paper towel or other object with a fluoresce property, exists within the waste detection zone, then the waste alert component may detect an increase in light due to the waste object fluorescing visible light in response to the ultraviolet light. If the increase in light intensity exceeds a detection threshold, then the waste alert component may provide a waste detection alert that the waste object exists within the waste detection zone (e.g., a message may be sent to a housekeeper that paper towel waste in on the bathroom countertop).

Abstract: According to one embodiment, an automatic analyzer comprises a light source, a spectroscope, a photo detection unit, a storage unit, a selection unit, and a calculation unit. The storage unit stores photo detector identifiers related to photo detectors and wavelength band identifiers in association with each other. The selection unit selects a specific photo detector from photo detectors. The specific photo detector corresponds to a specific photo detector identifier associated with a wavelength band identifier of a wavelength band according to a measurement item of a sample. The calculation unit calculates an absorbance related to the measurement item based on a signal from the selected specific photo detector.
