> The option itself is available in the ISODAT software but to use it you must have a second resistor physically installed on your board (what is normally the case in the standard CNOS setup that you order). You can either order the resistor you need (depends on what isotope ratio you are behind) through thermo or directly from the manufacturer. It can be installed by everybody having some basic practical experience with IRMS hardware.

I have a few questions about your instrument set up. Or maybe no one does this and we are the only ones who actually considered this sales gimmick as feasible?
