摘要： When using an electron capture detector for the molecular identification of electrophilic compounds, the sensitivity of the detector is made reproducible by controlling the voltage or frequency of the pulses applied to it to maintain a reference current whose set value is produced automatically by the device after determination of the characteristics of the state of the detector, namely a so-called saturation current CM and a so-called spontaneous current CS, according to a law of proportionality between these two currents.In addition, knowledge of these state characteristics gives information on the physical and physicochemical anomalies of the analysis device having an effect on the sensitivity of the detector, and consequently enables them to be remedied.

摘要： A method and apparatus for preventing the destruction of an alkali source in a nitrogen-phosphorus detector by certain reactive and derivatizing reagents encountered in gas chromatography is disclosed. Protection is afforded by lowering the temperature of an electrically heated alkali source during the period in which offensive substances in a gas under analysis are eluted, with the temperature of the source being restored after passage of the offensive substances. The temperature of the alkali source is changed by altering the current through an electrical resistance heater with a temperature control circuit that utilizes a wheatstone bridge.

摘要： A gas monitor comprising means for detecting changes in electron flow between two electrodes caused by absorption of the electrons by an electron capture gas flowing between the electrodes. A carrier gas is supplied to the detecting means at a predetermined velocity. A sample of the gas to be measured is added to the carrier gas by a valve means at a predetermined time which gas sample contains a trace of a first type of electron capture gas. The carrier gas together with any gas sample flows through a column means which slows down the velocity of any other type of electron capture gas in the sample with respect to the velocity of the first type of electron capture gas. The gas then passes through the detector wherein the electron capture gas causes a decrease in the electron flow between the electrodes. Means are provided for measuring the maximum decrease in the electron flow caused by the first type of electron capture gas and means are coupled to the measuring means for indicating the maximum decrease.

摘要： An asymmetric cylinder electron capture detector comprises an electrode configured to define an ionization volume, a source of ionizing radiation disposed within the ionization volume, a collector electrode, with a gas flowing past the collector electrode into the ionization volume. The electron current to the collector electrode provides an indication of the presence of electronegative constituents in the gas passing into the ionization volume. In order to provide wide dynamic range, the face of the collector electrode is disposed as close as possible to the electrode defining the ionization volume, yet is located so as to minimize field-free background current. The collector electrode and the electrode defining the ionization volume are each of cylindrical configuration, and are coaxially aligned but are spaced apart with respect to each other. The two electrodes are mechanically connected via an intermediately disposed cylindrical insulator cylinder. The collector electrode is received in one end of the insulator cylinder, and the electrode defining the ionization volume is received within the other end of the insulator cylinder. The collector electrode has an elongate portion extending into the interior of the insulator cylinder, but spaced apart from the inner surface of the insulator cylinder. This configuration provides a long insulative path to prevent electrical leakage between the electrodes. A transverse gas exit port is provided in that portion of the collector electrode within the insulator cylinder in order to impart turbulence to the flow of gas through the insulator cylinder into the ionization volume.

摘要： A counter flowing positive ion-negative ion neutralization chromatograph for analyzing gas samples containing helium and a species which forms negative ions. Two helium resonance lamps are mounted in a chamber with their windows in opposition. The lamps have an emission at 584A and the windows are partially transparent to radiation at 584A. An electrical field is maintained between the lamps. Positive and negative ion sheaths are formed respectively on the outer surface of the two aluminum windows. Because of the electric field, the sheaths move toward opposite windows. The interaction of the ions in the sheaths and impact with the aluminum windows provide information whereby optical and electrical measurements may be made.
