Product Overview
The Nu Instruments Horizon is a stable isotope ratio mass spectrometer (IRMS) designed for high-precision measurements of light stable isotopes including carbon, nitrogen, oxygen, sulphur and hydrogen. The Horizon combines a compact magnetic sector design with a versatile universal collector array, enabling accurate and reproducible isotope ratio determinations across a wide range of sample types.
The Horizon interfaces with elemental analysers, gas chromatographs and laser ablation systems to support applications in environmental science, food authenticity, forensics, ecology, geology and climate research. Its automated operation, excellent linearity and temperature-controlled flight tube ensure consistent, publication-quality data.
