Abstract:
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.

Claim (Index 1):
A gas inlet system for an isotope ratio spectrometer, comprising:\n a first supply of analyte gas; a variable volume reservoir; a first analyte gas supply line between the first supply of analyte gas and the variable volume reservoir for selectively supplying the analyte gas to the variable volume reservoir; a reservoir supply line for supplying the contents of the variable volume reservoir to the spectrometer; a volume varying means for adjusting the volume inside the variable volume reservoir; and a controller configured to generate a command so as to cause the volume varying means to adjust the volume inside the reservoir at a pre-determined rate, so as to control the flow rate of analyte gas output to the isotope ratio spectrometer as the volume of the variable volume reservoir is adjusted.
