The Nu Horizon IRMS instrument is designed for flexibility, reliability and high performance, with user friendly instrument control and data analysis software. This next generation instrument possesses unique features for both Dual Inlet (DI) and Continuous Flow (CF) analysis, interfacing with a wide range of sample preparation peripherals. The collector array uses the patented variable dispersion zoom optics to monitor masses from 2 to 100 with exact coincidence.

Sample preparation

The Nu Horizon is configured for a wide range of both CF and DI sample introduction systems. CF inlets are connected via an automated isolation valve and include capillary gas chromatography (Agilent 7890A) and elemental analysers (Eurovector or HEKAtech). The Dual Inlet is located in a separate cabinet with the sample inlet valve on the ion source housing, minimising dead volume and gas path lengths. DI sample options include a carbonate/phosphoric acid preparation unit, a water equilibration unit and a sample manifold with optional crackers.
