The Fingerprint Analysis Guide prepared by Energy Laboratories is an excellent reference tool for clients who have submitted a sample for analysis of petroleum products. Each was generated by a gas chromatograph into which a sample was carefully injected, then heated. Because each petroleum product differs in its composition, it can be identified by the unique “fingerprint” it produces.
Fingerprinting a specific sample not only identifies the petroleum product (or combination of petroleum products) within the sample, it may also potentially determine its age, source and level of degradation.
