Abstract
This research is aimed at making a comparison between a number of data analysis methods to measure the values of d13C and d18O in Carbon Dioxide for the SICAS. Consequently, a comparison against the IRMS is carried out for a range of reference calcites used to calibrate measurement devices. The dilution setup used to create the samples is optimized and then tested for reliability and ability to prevent altering of samples. The results show that the quadratic fit works best when analyzing the data and that the ratio and isotopologue method perform equally well overall. The residual values for d13C and d18O have been shown to be very consistent, leading to the conclusion that deviations from the norm occur mainly due to calibration issues. The IRMS has been proven to have an accuracy equivalent to the SICAS for the purposes of this experiment and the dilution setup has been confirmed to be reliable and prevent contamination of the sample.
