| 250339090 | With calibration steps in measurement process | 6 |
| 20090045342 | METHOD AND APPARATUS FOR DETERMINING AN ANALYTE CONCENTRATION IN A SAMPLE HAVING INTERFERENTS - A method and apparatus are described that permit an analyte concentration to be estimated from a measurement in the presence of compounds that interfere with the measurement. The method reduces the error in the analyte concentration in the presence of interferents. The method includes the use of a set of measurements obtained for a large population having a range of known analyte and interfering compound concentrations. From a sample measurement, which may or may not be one of the population, likely present interferents are identified, and a calibration vector is calculated. | 02-19-2009 |
| 20090127463 | Accessory for attenuated total internal reflectance (ATR) spectroscopy - An accessory for use with a microscope arranged to carry out ATR measurements has a support ( | 05-21-2009 |
| 20090230306 | Spectroscopic Prediction of Formaldehyde Emission and Thickness Swell of Wood Panels - A process for spectroscopic measurement of the emission of formaldehyde from refined wood products destined to be used in the manufacture of composite wood products such as medium density fiberboard (MDF), particleboard, and plywood. The process employs near-infrared (NIR) spectroscopy to measure the absorption of light by the wood furnish; the level of absorption is then related to the formaldehyde emission and thickness swell of the finished wood panel. This process allows for real-time quantitative prediction of future formaldehyde emissions and thickness swell of a composite wood panel. | 09-17-2009 |
| 20100038544 | Thermal Effect Measurement with Mid-Infrared Spectroscopy - A method of determining a physical property of a composite material includes providing a series of composite materials/surfacing films, which are subjected to increasing thermal experience to create a set of thermal effect standards, collecting mid-IR spectra on those standards, performing data pre-processing and then multivariate calibration on the spectra of the composite materials/surfacing films, and using that calibration to predict the thermal effect for samples in question. | 02-18-2010 |
| 20150076352 | INFRARED SPECTROMETER MEASUREMENT OF DROPLETS COLLECTED FROM AN OIL MIST IN A BREATHER PIPE OF A GAS TURBINE - A method for analysing a droplet fraction of an oil mist sample of a gas turbine is provided. A collecting device collects the oil mist sample, wherein the collecting device is arranged within a breather pipe which is coupled to the gas turbine such that oil mist is flowing through the breather pipe. The droplet fraction is separated from a gaseous fraction of the oil mist sample by a filter device, wherein the filter device is soaked with the droplet fraction, the droplet fraction is extracted from the filter device by using a tetrachloroethylene solvent. A composition of the droplet fraction is analysed by a spectrometer. | 03-19-2015 |
| 20160123872 | METHOD AND SYSTEM FOR NIR SPECTROSCOPY OF MIXTURES TO EVALUATE COMPOSITION OF COMPONENTS OF THE MIXTURES - A method of estimating the relative concentration of at least two components contained in a mixture of the components is disclosed. At least two mixtures are produced by combining the at least two components, each of the at least two mixtures having different concentrations of the at least two components. NIR mixture spectra are acquired from each of the at least two mixtures. The NIR component spectra and the NIR mixture spectra are input into a computer utilizing chemometrics software and the spectra are analyzed to produce a calibration model for each component and each of the mixture NIR spectra. NIR monitored spectra for a monitored mixture of the components having an unknown concentration of the components is acquired. The calibration models are applied to the NIR monitored spectra to thereby estimate the concentration of at least one of the components in the monitored mixture. The method can be applied to monitor fluid mixtures produced from one or multiple hydrocarbon reservoirs and surface facilities including pipelines and tanks. | 05-05-2016 |
