Thi Hao BuiMcGill University - GeotopCompound-specific isotope analyses are done in our lab using the GC-IRMS coupled with a combustion reactor (for d13C) or a high-temperature conversion reactor (for d2H). The standards n-Alkane Mixture Type A6 and Fatty Acid Ester Mixture F8-3 are used to calibrate the d13C and d2H of alkanes and fatty acids, respectively. We needed house standards, which were relatively large ...
