scope:

This method is applicable to the qualitative and quantitative determination of naphthenic acid in wood and solutions containing waterborne copper naphthenate. This method also covers the identification of synthetic carboxylic acids and other non-naphthenic carboxylic acid contaminants in naphthenic acids in copper naphthenate. This procedure will identify the presence of copper naphthenate or naphthenic acid in treated wood and is not intended for determination of trace levels in wood. This gas chromatographic method for analysis of solutions was originally published in Proc. AWPA 95, 133-137 (1999) as an attachment to the 1999 Subcommittee P-5 Report.
