Horizon 2
Designed for flexibility, reliability and high performance, with user friendly instrument control and data analysis software.
Product Details
The Nu Instruments Horizon 2 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 Horizon 2 has a wealth of novel features, giving the ultimate in performance for both routine and research applications for stable isotope ratio measurements. The Horizon 2 Ion source runs up to 7kV acceleration potential. Its unique patented zoom optic system and narrow Faraday cups achieve exact peak coincidence, enhance peak shape and abundance sensitivity, thus increasing accuracy. The Mini Electro-Static Filter in front of the mass 3 (DH) collector eliminates low energy He+ ions from the HD+ ion beam. The true differential pumping for the source and analyser block exhibits less ion beam scattering inside the analyser and therefore reduces the background noise in CF mode.
Sample preparation
The Horizon 2 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 (GC Interface), elemental analyser (Nu Ember) and a headspace analyser (Gas Prep) system. 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 preparation unit (Nu React), and multi-port manifold with optional automated crackers.
Application
Nitrogen and Carbon Stable Isotope Analysis
Reliable δ¹⁵N and δ¹³C measurements across a wide range of sample types and sizes. This application note demonstrates excellent stability, precision and linearity for routine elemental analyser isotope ratio mass spectrometry (EA-IRMS) workflows.
Prep System
Sequential S, N and C Isotope Analysis by EA-IRMS
This application note presents a practical solution for sequential sulphur, nitrogen and carbon isotope measurements within a single EA-IRMS analysis. The method combines innovative gas handling with the Horizon IRMS to deliver fast, accurate and high-throughput SNC isotope analysis.
