Services

Elemental analysis: Equipped with a varioMICRO cube elemental analyzer, we provide elemental analyses of carbon, nitrogen, and sulfur. VarioMICRO’s purge and trap chromatography technology contributes to the precision of our nitrogen separation and sulfur analyses. (Fig. 6)

 

Stable isotope analysis: Our IsoPrime 100 isotope ratio mass spectrometer affords us high-precision measurements with its exceptional per meg performance. (Fig. 7)

 

Sample preparation: We also provide sample preparation services (Mettler Toledo XP6 microbalance) for an additional fee (grinding, acidification, encapsulation, mass). Please contact us for a quote. (Fig. 8)
