n-Alkane Analysis
We routinely support CSIA of 13C in n-alkanes. n-Alkanes dissolved in hexane are injected in splitless mode and separated on a Varian factorFOUR VF-5ms column (30m X 0.25mm ID, 0.25 micron film thickness). Once separated, n-alkanes are quantitatively converted to CO2 in an oxidation reactor at 950°C. Following water removal through a nafion dryer, CO2 enters the IRMS. Delta 13C values are corrected using working standards composed of several n-alkane mixtures that are calibrated against NIST standard reference materials.
