A rotary dosing device for use in analytical instrumentation quickly transfers a sequence of precise molar quantities of gas from a primary stream into a secondary stream. The device has a rotating chamber with dosing ports that cycle through three states: fill, equilibrate, and transfer. The device cycles in an overlapping manner such that as one dose volume fills with gas from the primary stream, another equilibrates at a known pressure and temperature, and another transfers its contents to the secondary stream. The device initiates its operation so that the first transfer in a sequence is a properly filled and equilibrated dose from the primary stream. Rather than cycling a single dose volume through the three states multiple times, the overlapping operation of the rotary doser enables multiple precise molar quantities of gas to be transferred in one-third the time.

The invention relates to a method and the device which is required for its performing for the determination of the isotope ratio of carbon and/or nitrogen in an aqueous mobile phase which contains a sample. The method comprises the following steps: introduction of the aqueous mobile phase into a reactor (i), heating of the aqueous mobile phase with addition of oxygen in the reactor to a temperature of higher than 600° C. for the formation of a water containing sample gas (ii), reduction of the nitrogen oxides being present in the sample gas as well as removal of the contained oxygen (iii), removal of water from the sample gas by chemical drying and/or membrane gas drying (iv) and introduction of the dried sample gas into an isotope mass spectrometer (v). It is essential for the present invention that the introduction in step (i) is realized by introducing the aqueous mobile phase in a capillary tube which leads into the reactor with a gas mixture of oxygen and at least one inert gas, wherein the mass flow of oxygen and inert gas is regulated or controlled by at least one mass flow controller which is upstream with respect to the introduction and that after step (iv) removed water is actively pumped off.
