Measurement of isotopologues of gas species with the MAT253 Ultra

Mass spectrometers dedicated to the measurement of stable isotopes of light elements such as those of nitrogen ( ¹⁵ N and ¹⁴ N), carbon ( ¹³ C and ¹² C), oxygen ( ¹⁸ O, ¹⁷ O, ¹⁶ O), sulfur ( ³⁶ S, ³⁴ S, ³³ S, ³² S) or hydrogen (H and D) were developed in the late...
