Abstract

Isoprime now introduce the precisION stable isotope ratio mass spectrometer with the highly versatile IONOS software. This innovative combination delivers useful instrument flexibility to pursue isotope science across the broadest spectrum of research. The ability to acquire up to 10 ion beams simultaneously at a resolution of 110 with large dynamic range 100V amplifiers permits samples to be analysed at the highest level of performance. The instrument and software presents a straightforward user interface whilst offering complete control of every hardware parameter. Automation of tasks, flexibility with interfacing and ease of analytical data output are enabled with the inclusion of the centrION interface and IONOS software. Central to precisION is the ability for the user to generate and incorporate customized inlet systems. The NICM (novel inlet control module) can incorporate and automatically control a large range of devices providing access to valves, mass flow controllers, motors, gauges and sensors. The isoFLOW preparation system is the new generation gas analyzing devised to maximize these advantages for gas analysis. The introduction of solid‐state cooling technology enables sub‐zero temperatures without cryogenics or refrigerants, eliminates all moving parts, and increases analytical longevity due to no boiling losses of coolant. This new technology makes it possible for the system to be deployed as both a focusing device and as a gas separation device. Initial data of synthetic gas mixtures (CO2/CH4/N2O in air), and real‐world applications including long‐term room air, solid carbonates and a comparison between carbonated waters of different origins show excellent agreement with previous technologies.
