Fingerprinting of the extractives in woods and pulps may provide mills with a tool for monitoring species changes and product qualities, and to help with process problems. Techniques consist of gas chromatography (GC) for the analysis of dichloromethane (DCM) extractives and high performance liquid chromatography (HPLC) for the dimethylformamide (DMF) extractives. In this way complementary information on the non-polar and polar components can be obtained. A variety of wood chips, hardwood, softwood, heartwood and sapwood, and a number of chemical and mechanical pulps were studied. The differences observed in the fingerprints provided valuable information on assignment of species, age of the wood and pulping process changes.
