The workhorse in isotope ratio analysis

The vario ISOTOPE select is the entry-level EA dedicated to stable isotope analysis, combining reliable results with outstanding robustness. It utilizes Elementar's proprietary Advanced Purge and Trap technology with a single Temperature Programmed Desorption (TPD) column. Thus, full baseline resolution during simultaneous CNS isotope ratio analysis is always guaranteed. In combination with one of our high performance IRMS systems, you will always get the best out of your analyses.

Reliable results

The vario ISOTOPE select guarantees outstanding precision and accuracy through quantitative combustion via controlled oxygen jet-injection directly into the active zone. This leads to matrix-independent results even for samples which are difficult to combust. In combination with the state-of-the-art thermal conductivity detector, the instrument provides an elemental detection limit.

All elemental analyzers from Elementar are designed for minimal sample preparation and secure, unattended 24/7 operation. They use the safe, simple and environmentally friendly high-temperature combustion.
