摘要： The invention relates to a device for producing CO2, N2 and/or SO2 from a sample for a quantitative analysis of the sample, comprising a reactor structure and metals acting in an oxidizing manner or metal oxides in the reactor. According to the invention, the reactor structure has at least two zones through which the sample can flow, which is to say a first zone with reactor metal and reservoir metal, or only reactor metal, and following the first zone, a second zone with reactor metal and reservoir metal, or only reservoir metal, wherein both metals can form oxides, and wherein the ratio of the reactor metal to the reservoir metal in the first zone is greater than in the second zone.

摘要： A gas inlet system for an isotope ratio spectrometer and a method for coupling analyte gas to an isotope ratio spectrometer are disclosed. A variable volume reservoir is located between a supply of analyte gas and a spectrometer. The reservoir's internal volume is controllably adjusted at a pre-determined rate to generate a defined flow of analyte gas or mixture to or from the reservoir. Analyte gas and carrier gas are taken up by the reservoir on increasing the reservoir's internal volume and then expelled from the reservoir to the spectrometer on decreasing the reservoir's internal volume. An open split can be used together with the reservoir to facilitate splitting away and hence dilution of analyte within the reservoir. A method for cleaning the gas inlet system is provided, which involves flushing the system with carrier gas.

摘要： A high voltage feedthrough assembly comprises an electrical lead extending in a longitudinal direction and an insulative cover capturing the electrical lead and extending along the electrical lead. The high voltage feedthrough assembly also comprises a flange, the insulative cover extending through and being held by the flange, so that the electrical lead extends through the flange. An adapter body has a cavity extending therethrough, is held in a spaced relation to the flange, the width of the cavity being greater than the width of the insulative cover, wherein a portion of the insulative cover and the electrical lead extending from the flange extends into the cavity. A collar is arranged in the adapter body cavity, extending radially between the adapter body and the insulative cover, to hold the insulative cover and electrical lead so that the insulative cover is radially spaced away from the cavity.
