Spectrometers for stable isotopes
Tandem Laboratory has a Horizon IRMS (Isotope Ratio Mass Spectrometer) from Nu Instruments. It is equipped with a 20-port manifold and dual inlet for offline measurement of δ13C. It is also equipped with an Eurovector 3000 EA for measurement of δ13C and δ15N in continuous flow mode.
The Tandem Laboratory also has two Elementar PrecisION IRMS that is coupled between two AGE3 graphitization systems from Ionplus and vario MICRO cube EA from Elementar. These measure δ13C and δ15N for all samples.
