Abstract:

The IRMS Data Processing software package is designed to allow easy stable isotope data entry and multivariate data analysis. When comparing two of more hydrocarbon samples using compound-specific isotope ratio mass spectrometry, an analyst obtains multiple data variables for each sample. Multivariate statistics allows rigorous comparisons to determine if the samples are in fact different and if so, how closely related they are. This software uses three main types of data analyses Multiple Analysis of Variance MAN0VA, Principal Components Analysis PCA, and Cluster Analysis. The layout is a standard Windows interface which should be usable to anyone familiar with modem operating system software.
