We used Gas Chromatography and now we also used another instrument to verify our results. The Delta V plus mass spectrometer primarily designated to measure the isotope ratio of H/D, ¹⁵N/¹⁴N, ¹⁸O/¹⁶O, ³⁴S/³²S, ³⁷Cl/³⁵Cl and most important one ¹²C/¹³C and other elements that can be transformed into gaseous substance. The gases used with this type of IRMS are CO₂, H₂, N₂, NO, O₂ etc.

We are working on Amino Acid samples to measure Nitrogen Isotopes. For our lab we are having secondary inlet system for up to 20 samples. We can use samples in very small amount and the results are done at IRMS.

We are using Isobat 2.5 software suite for system control, data acquisition and data evaluation that is an integral part of the system architecture.
