摘要： A gas measurement and analysis system having a gas chromatograph which converts a gas mixture from a source to a time varying continuous signal. This signal is sampled and converted to digital form by an analog to digital converter which provides a stream of amplitude dependent digital values at equally spaced time intervals. These sampled signals are applied to a rate of change estimator system which provides an accurate estimate of the time derivative of the sampled signal by means of recursive digital feedback. The output of the estimator system is applied to a processor.

摘要： A system receives output signals from a gas chromatograph and integrates on a real time basis the area under peak curves superimposed on an exponentially decreasing solvent tail. Integration of a peak curve is performed in two parts. First, a constant level baseline correction signal is established at the starting point of the peak, the the curve is integrated with respect to the baseline correction signal during the time interval between the starting point and the crossover point of the peak curve and the baseline correction signal. Secondly, the peak curve is integrated with respect to both the baseline correction signal and a derived peak correction signal during the time interval between the crossover point and an end point of the curve. The sum of the two integrals indicates the area between the peak curve and a sloping baseline which extends from the starting point of the peak curve and is tangent to the exponentially decreasing solvent tail at an end point of the peak curve.

摘要： Apparatus for integrating the area of a succeeding peak superimposed on the tail of a preceding peak in the output of a measuring instrument. The apparatus comprises means for providing for the output of the instrument a temporary base line which has the slope of the tail at a point in the valley between the two peaks and which extends under the succeeding peak; means for integrating the area under the succeeding peak and above the temporary base line; means for calculating the excess of the integrated area caused by the temporary base line; and means for subtracting the excess area from the integrated area to obtain the area of the succeeding peak.

摘要： An electronic system for computing the integrals of various fractions of the time varying electrical output of a scanning densitometer provides that output to a graphic recorder, an analog-to-digital converter and to a slope detector which generates signals representing the boundaries of various fractions of the signal. This detector output is also provided to the recorder to produce a curve representing the amplitude variations of a densitometer signal with marks at the boundaries. The outputs of the analog to digital converter and the slope detector are provided to a shift register. An operator generates correction signals based on an observation of the recorder trace representing desired changes in the boundaries as determined by the slope detector. The densitometer output of the shift register is integrated over time periods controlled by the boundary output of the shift register as manually corrected.

摘要： A circuit for integrating, storing and analyzing a signal having a plurality of peaks, such as the output of a gas chromatographic detector, in which each of a plurality of storage capacitors is successively connected to an integrator for storing each signal peak integrated. The signals being integrated may be compensated in order that the stored integrals are all on the same basis, e.g., weight percent. After storage of all of the integrals, the total integral and each of the individual integrals may be read out through a buffer which operates to inhibit discharge of the storage capacitors during readout. A voltage control circuit applies a signal to the input of the buffer approximately equal to the value of the total integral to inhibit transients during readout. The values of the stored integrals may be read out in absolute or relative units, for example, each individual integral may be read out as a percentage of the value of the total integral.

摘要： A method and apparatus for continually monitoring a component of a fluid mixture, such as the naphthene content of a hydrocarbon mixture. The apparatus includes a microreactor for subjecting the fluid mixture to a chemical reaction converting, at least in part, a fluid component of the mixture so as to render the fluid component of interest separable from the mixture, and detection means for detecting the fluid component of interest. In a further embodiment a unique computer is provided coupled with the detector for computing the concentration of the fluid component of interest in the fluid mixture. The method of the invention includes reacting the fluid mixture in the aforementioned chemical reaction, and detecting the fluid component of interest. In another version of the method in which the reaction affects more than one component of the mixture converting the affected components to still another component of the mixture, the method includes the further steps of detecting said other component in an unreacted sample of the fluid mixture and generating a signal representative of the concentration in the mixture of the fluid component of interest in accordance with a predetermined relationship between the detected components of the unreacted sample, the reacted sample, and the concentration of the fluid component of interest in the fluid mixture.
