Chain of Custody
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.
Any of the routine gas chromatography data can be processed to determine
the correlation coefficients of two or more samples. See Wigger
