Durability of wood and wood-based products - Quantitative determination of pentachlorophenol in wood - Gas chromatographic method

Scope

This Technical Report specifies a laboratory method of determining the pentachlorophenol content of wood. The method is applicable to all types of PCP- treated wood and wood-based materials as well as for the analysis of waste timber with respect to its PCP content.
The method has a quantification limit corresponding to 100 µg PCP per kilogram of wood material expressed as dry matter. The method described has a measurement range up to PCP contents of 25 mg/kg of dry matter. These figures refer to the given example (where an aliquot of 1 ml of the extract is used for acetylation, see 8.4).
NOTE 1 If lower quantification limits are required, a higher volume of extract aliquot can be used for derivatisation.
NOTE 2 This method could have some modifications with some wood species as hardwoods.
