Interpretation Assistance


TGI can provide a written interpretation of the analytical results of the hydrocarbon fingerprinting (gas chromatography) analysis. These reports typically include an opinion of the type or types of products indicated by the chromatogram, an estimation of the degree of weathering, an estimation of the age of the product and an opinion of the degree of similarity to other samples.


Informal help with sampling plans or evaluation of data can be provided via telephone or e-mail.

Statistical Evaluation:

Any of the routine gas chromatography data can be processed to determine the correlation coefficients of two or more samples. See Wigger J.W. and Torkelson B.E. (1997)
