摘要： Apparatus and methods are provided for reducing coherent noise in measurements of repetitive analog signal waveforms by digital signal averagers. Coherent noise is repetitive and synchronous with the signal waveform and is therefore undiminished by conventional signal averaging techniques. A major source of coherent noise is the repetitive voltage transitions that occur within the digital signal averager itself. The apparatus and methods of the present invention introduce a known and variable phase offset during the signal averaging process between the signal waveform being measured and the internally generated coherent noise, thereby allowing such coherent noise to be averaged, and therefore reduced, during the signal averaging process. Consequently, the apparatus and methods of the present invention allow greater signal-to-noise ratio and signal dynamic range than with the prior art.

摘要： A method for analyzing a gas sample is described. The method comprises providing a gas sample, increasing pressure applied to the gas sample to compress the sample to a smaller volume and provide a pneumatically focused gas sample, and analyzing the pneumatically focused gas sample using any of a variety of analytical techniques. Pneumatic Focusing generally means increasing the pressure of the sample, column or cell to a pressure of from about 100 psi to about 15,000 psi, more typically from about 200 psi to about 2,000 psi. Examples including gas chromatography and absorption spectroscopy are illustrated herein. Numerous other examples could be given. The method is well suited for analyzing gaseous samples, such as ambient air samples, both continuously, and remotely, using computer control. Continuously sampling ambient air provides a method for real-time monitoring of air quality. Continuous monitoring allows for pollutant exposure and allows for the identification of emission sources. The method is also well suited for analysis of breath exhalations from respiring organisms useful in metabolic studies or disease diagnosis.

摘要： A measuring part measures the absorbance spectrum of an effluent fluid sample from a chromatograph in a constant cycle, and a base line calculating part calculates a base line including absorbance values on both ends of a designated wave number range with respect to every absorbance spectrum data as measured. A peak area calculating part calculates the peak area of the absorbance spectrum in the designated wave number range on the basis of the decided base line. A chromatogram is obtained by time change of the calculated peak area. Thus, it is possible to eliminate influences by other functional groups and fluctuation of the base line in an absorbance analyzer.

摘要： Multiple electropherograms or chromatograms representing successive stages of an electrophoretic or chromatographic separation in a capillary are obtained by training a recorder on a succession of detection windows in the capillary, spaced apart along the capillary length. A single immovable detector is used, and the capillary is either held such that each detection window is placed in alignment with the detector in succession, or is looped such that the detection windows all lie in the path of the detector at the same time.

摘要： A method and apparatus is disclosed for correcting errors in a chromatographic analysis wherein the trailing edge of a strong peak interferes with the integration of the trailing peak which follows the strong peak. In one embodiment of the invention two functions of the trailing peak are electrically integrated and summed to produce a correct peak integration. In a second embodiment of the invention the baseline is shifted and the integration of the trailing peak is performed with respect to the shifted baseline to produce a correct peak integration.

摘要： A primary signal network which compensates for drift error developed in a voltage-integrating network operating on the primary signal voltage. A compensating voltage is developed in the primary signal network independent of the normal primary voltage signal. This compensating voltage offsets the drift voltage and improves the accuracy of the integration of the primary signal voltage over the period of measurement and integration.
