Large‐Volume Injection and Assessment of Reference Standards for <i>n</i> ‐Alkane δD and δ <sup>13</sup> C Analysis via Gas Chromatography Isotope Ratio Mass Spectrometry
The large-volume injection method shows good reproducibility of δ<sup>13</sup>C and δD measurements of n-alkanes and reduces the required sample concentration by about 80%. We propose that for δD measurements, a reference standard set should be used in which each reference standard has a limited range of δD values and no adjacent n-alkane chains, to minimize memory effects.
