    Abstract: A chromatography system includes a separation column that separates a sample carried by a compressible mobile phase flow into analytes and a splitter in fluidic communication with the separation column to receive and divide the compressible mobile phase flow into first and second mobile phase streams in accordance with a split ratio. A thermally modulated variable restrictor is coupled between the splitter and a detector. The restrictor receives the first mobile phase stream from the splitter and has a temperature element in thermal communication with the first mobile phase stream to exchange heat therewith. A controller, in communication with the restrictor, dynamically adjusts a temperature setting of the temperature element of the restrictor to adjust the heat exchange between the thermally modulated variable restrictor and the first mobile phase stream in order to keep the split ratio constant throughout a chromatographic run.

    Abstract: A method and apparatus for introducing a reference gas into isotope mass spectrometer systems. The reference gas is introduced into the system before a combustion interface and yields Gaussian shaped peaks of the same form as those produced for sample constituents. In one embodiment of the present invention the gas inlet comprises three pipes which intersect at an intersection point wherein a reference gas and a secondary flow of a carrier gas can enter the inlet via separate pipes and can exit via the third pipe before the secondary flow enters the combustion interface.
