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. TEMPERATURE PROGRAMMED DESORPTION (TPD) Elementar’s proprietary TPD technology is a unique high performance chromatographic technique for the determination of non- metal elements. The fractionation-free TPD technology is capable of resolving e.g. C?/?N ratios of up to 5000?:?1 and C?/?S ratios of up to 4000?:?1. The distinct peak separation assures absolutely reliable and trouble- free data acquisition. The data analysis can therefore be easily automated for larger sample amounts while maintaining highest possible data quality. Elementar’s unique TPD columns are optimized to provide unmatched robustness and longevity compared to GC columns. Furthermore, the vario ISOTOPE select can be loaded up to 4-fold higher, resulting in outstanding sample flexibility. The analysis of samples with an absolute carbon content of up to 7?mg is therefore possible in CNS mode. Thus, customers enjoy industry-leading accuracy, sensitivity and versatility. HIGH-TEMPERATURE COMBUSTION All elemental analyzers from Elementar are designed for minimal sample preparation and secure, unattended 24?/?7 operation. They use the safe, simple and environmental friendly high-temperature combustion principle. The proven Elementar furnace technology combined with efficient oxygen dosing guarantees quantitative conversion of the sample to measuring gas – a prerequisite for highly precise and matrix-independent elemental and isotope ratio analysis. Reliable results The vario ISOTOPE select guarantees outstanding precision and accuracy through quantitative combustion via con - trolled oxygen jet-injection direct ly into the active zone. This leads to matrix-independent results even for samples which are diffcult to combust. In combination with the state-of-the-art thermal conductivity detector, the instru- ment provides an elemental detection limit of
