Delta V Plus Spectrometer
The device is used to measure the composition of stable isotopes of light elements with masses from 10 to 80 Da and additionally hydrogen (mass 2 and 3 Da) using the differential method. The principle of the operation consists in separating individual masses of ions in a homogeneous magnetic field and then capturing and counting them in a detector equipped with Faraday cans. The sample is introduced into the spectrometer in gaseous form. Depending on the analyzed element, the working gas is: when measuring carbon - CO2, nitrogen - N2, oxygen - CO2 or CO, hydrogen - H2, sulphur - SO2. Depending on the type of measuring substance (solid, liquid, gas) and the analysed element, the spectrometer is coupled with various interfaces used for their preparation for measurement (elemental analyser FLASH 2000, Trace GC Ultra chromatograph, Gasbench II, TC/EA, Precon).

Isotopic analysis can be used to determine the source of a substance, to reconstruct past environmental and climatic conditions and to investigate various geological, paleontological and chemical processes.
Measurement of the composition of stable isotopes C, H, N, O and S in solid, liquid and gaseous substances. The measurement is carried out using the "on-line" method. The uncertainty of the analysis of stable isotopes, taking into account the preparation and referencing to the standard, is +/- from 0.2 ‰ to 1 ‰ depending on the analyzed element.
