Multi-isotope analysis, determination of isotope ratios by Continuous Flow Isotope Ratio Mass Spectrometry CF-IRMS – a powerful analytical method used to authenticate both raw materials and finished products in the food industry and by national food control laboratories.

2. Wine: multi-component and multi- isotopic analysis

3. CF-IRMS DELTA V PLUS The CF-IRMS DELTA V PLUS is a new generation of Isotope Ratio MS, more sensitive while delivering excellent linearity and stability, more versatile and more rugged than predecessors. The conversion of any type of organic or inorganic compound into simple gases is the basic principle for IRMS. A wide range of sample preparation devices and interfaces are available as inlets: I. ConFlo III Universal Interface allows the connection of a wide variety of Elemental Analyzers to the Delta V including Dumas combustion elemental analyzers for 13 C/ 12 C, 15 N/ 14 N, quantitative high temperature carbon reduction elemental analyzers for D/H and 18 O/ 16 O (Flash EA/TC). ) II. The GasBench II (18O/16O – equilibration water content in wine) is a flexible continuous flow preparation device and inlet system with Repetitive loop injection of gases. Is supported by a robotic autosampler and using septum-sea led sample vials.
