APPLICABILITY: The working range is 9 to 360 ppm (50 to 2000 mg/m 3) for a 10-L air sample. Turpentine is widely used as a solvent in paints, varnishes and lacquers.
INTERFERENCES: The chief constituents of turpentine are pinene isomers, diterpene and other C 10H 16 terpenes. Naphtha mixtures containing C 9-C11 alkanes or alkyl-substituted benzenes could cause interferences with the turpentine mixture. GC column and conditions should then be optimized for maximum resolution.
OTHER METHODS: This is Method S88 [3] in a revised format.
