摘要： Several methods of calibrating a wavelength-modulation spectroscopy apparatus configured to measure a concentration of an analyte in a sample gas are disclosed. Each of the methods allows for calibration and recalibration using a relatively safe gas regardless of whether the sample gas for which the concentration of the analyte can be determined is a hazardous gas. In one embodiment of the invention, calibration that is sample-gas specific is accomplished by determining a first slope coefficient and calibration function for the sample gas, after which a scaling factor can be determined based on the first slope coefficient and a second slope coefficient for the same or a different sample gas and used in a subsequent calibration (or recalibration) to scale the calibration function. In other embodiments of the invention, calibration that is not sample-gas specific is accomplished to allow for the determination of the analyte concentration in variable gas compositions and constant gas compositions.

摘要： A method of analyzing a gas specimen mixture includes measuring the concentrations of inert components in the gas specimen mixture and the pressure and temperature of the gas specimen mixture. A number of sample gas mixtures are generated with varying percentages of hydrocarbon gases, each including the measured inert component concentrations. For each generated sample gas mixture, the method includes calculating the speed of sound therein based on the measured pressure and temperature and the particular percentages of hydrocarbon gases therein, measuring the speed of sound in the gas specimen mixture, and iteratively comparing the measured speed of sound with the calculated speed of sound in different sample gas mixtures until convergence for a particular sample gas mixture.

摘要： A sensor responds to a magnetic wind produced by the magnetic susceptibility of a target component gas, such as oxygen, which is present together with a background gas in a sample located in a measurement field produced in a measurement device. A background sampler also determines thermal and physical characteristics in a conditioned flow path, and a processor performs a computational correction on the detected magnetic wind signal to more accurately determine the concentration of the target gas. The background sampler includes a mass flow cell in series with a laminar flow device to measure heat capacity and viscous properties of the sample. It derives the gas viscosity from a differential pressure measurement; and preferably determines the heat capacity and thermal conductivity of background gases, the composition of which may be unknown, to compensate for their effects on the magnetic wind sensor elements. A further correction for diamagnetism of the background is made using one or more correlations between the measured parameters in certain common gases or classes of gases. The determination of gas bulk properties allows the concentration of the target gas to be made with enhanced accuracy in the presence of unknown, unquantified or changing background components, and the necessary hardware may be used in conjunction with existing magnetic wind sensor and processor. In that case, the processor program is modified to apply the additional sensor inputs to correct the magnetic wind reading. A thermal conductivity correction is also made, and this may be directly derived from the bridge control signal when operating the magnetic wind sensors in mode to maintain constant temperature. The system may be used in petroleum tanks and hydrocarbon vent systems to monitor for explosive levels of oxygen.

摘要： A method for harvesting crop materials each having a grains carrying stalk, includes erecting the stalk, cutting the stalk of the crop materials with two or more cutting blades or elements into a lower base segment carrying no grain and an upper straw segment that carries grains, discarding the lower base segment which carries no grain, threshing the upper straw segment which carries the grains for separating the grains from the upper straw segment, and collecting the grains. A blowing process is used for blowing the upper straw segment away from the grains before collecting device the grains. A determining process is used for determining a length of the lower base segment to be cut before erecting the stalk.
