Abstract: Various embodiments disclosed relate to methods of predicting neutral detergent fiber digestibility (NDFD) properties of a feedstuff sample. A method of predicting neutral detergent fiber digestibility (NDFD) properties of a feedstuff sample includes collecting a near-infrared spectrum of the feedstuff sample to provide NIR data of the feedstuff sample. The method also includes predicting NDFD of the sample at an elapsed time, NDFD rate of the sample, and/or NDFD extent of the sample from the NIR data using a NIR/NDFD calibration model. Various embodiments provide a method of developing the NIR/NDFD calibration model using in vitro gas production (IVGP). Various embodiments provide a method of predicting digestibility of the feedstuff sample for an animal at a rumen passage rate (eNDF).

Abstract: Methods and assemblies may be used for determining and using standardized spectral responses for calibration of spectroscopic analyzers. The methods and assemblies may be used to calibrate or recalibrate a spectroscopic analyzer when the spectroscopic analyzer changes from a first state to a second state, the second state being defined as a period of time after a change to the spectroscopic analyzer causing a need to calibrate or recalibrate the spectroscopic analyzer. The calibration or recalibration may result in the spectroscopic analyzer outputting a standardized spectrum, such that the spectroscopic analyzer outputs a corrected material spectrum for an analyzed material, and defining the standardized spectrum. The corrected material spectrum may include signals indicative of material properties of an analyzed material, the material properties of the material being substantially consistent with material properties of the material output by the spectroscopic analyzer in the first state.

Abstract: A measurement device for spectroscopic constituent analysis includes a control unit, a light source, a sample holder arranged in the beam path of the light source, and a spectral measurement module. The measurement module comprises at least one photosensor with organic photodiodes arranged on a substrate and a temperature sensor arranged at the photosensor. During a sample measurement, a method using the measurement device comprises: detecting an actual temperature at the photosensor; pivoting-in a dark reference sample and measuring a dark reference value; pivoting-in a bright reference sample and measuring a bright reference value; measuring a spectral value of the sample and correcting the spectral value by means of a correction calculation by way of the control unit using the dark reference value, the bright reference value, the spectral value of the sample, the temperature and using values which were determined in a pre-calibration and stored in the control unit.

Abstract: An apparatus (100) for measuring not only the reflected radiation but also the fluorescence emission of a textile sample (106), which includes a presentation subsystem (102) having a viewing window (108). A radiation subsystem (114) has a tunable radiation source (120) for directing a desired radiation (122) having a wavelength range and an intensity through the viewing window (108) toward the sample (106), and thereby causing the sample (106) to produce a fluorescence (124). A sensing subsystem (126) has an imager (130) for capturing the reflected radiation and fluorescence (124) in an array of pixels. A control subsystem (132) has a processor (136) for controlling the presentation subsystem (102), the radiation subsystem (114), and the sensing subsystem (126), and creates a reflected radiation and fluorescence image containing both spectral information and spatial information in regard to the reflected radiation and fluorescence (124) of the sample (106).

Abstract: Disclosed is a method for measuring the absorbance of light of a substance in a solution in a measuring cell (23; 223′), said method comprising the steps of: transmitting (S1) a first light beam (27; 27′) from a light source (25; 25′) towards a beam splitter (29; 29′); dividing (S3) the first light beam (27; 27′) into a signal light ray (31; 31′) and a reference light ray (33; 33′) by the beam splitter (29; 29′); modulating (S5) the signal light ray (31; 31′); modulating the reference light ray (33; 33′); providing (S9) the measuring cell (23; 23′) such that the signal light ray (31; 31′) passes through the measuring cell; detecting (S11) a signal in a detector (39; 39′), which signal is the combined signal intensity of the signal light ray (31; 31′) and the reference light ray (33; 33′) detected by the detector (39; 39′); performing synchronous detection (S15) of the detected signal in order to reconstruct the intensities of the signal light ray (31; 31′) and the reference light ray (33; 33′) from the combined signal detected by the detector (39; 39′), said synchronous detection being based on the modulation performed to the signal light ray and the reference light ray. Disclosed also is a measuring device for carrying out said method.

Abstract: An inspection device for inspecting an analyte in a liquid is provided, including a light source module, a first polarizing member, a second polarizing member, a sensing member, and a calibration assembly. The light source module provides a light, and the first polarizing member is disposed between the light source module and the second polarizing member. An accommodating space for accommodating the aforementioned liquid is formed between the first polarizing member and the second polarizing member. The second polarizing member is disposed between the first polarizing member and the sensing member. When the inspection device inspects the liquid, a portion of the light passes through the first polarizing member, the liquid, and the second polarizing member and reaches the sensing member, and another portion of the light enters the calibration assembly.

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: A method for determining a measure of a gas concentration from a group of at least two non- dispersive infrared, NDIR, gas sensors (S1-SN) is described. The method comprises the steps of obtaining, at a processing unit (1), from each NDIR gas sensor (S1-SN) a measure of a gas concentration as a belief function Pi(x), which provides a probability as a function of the sensed light intensity at a specific wavelength, merging, in the processing unit, the belief functions Pi(x) to a merged belief function P(x). A computer program performing the method is also described.
