Method 1551


This method is used for the determination of turpentine.  The sample is collected on a charcoal tube.  After collection the sample is desorbed with carbon disulfide and then analyzed using GC/FID (flame ionization detector).  The chief constituents of turpentine are pinene, diterpene and other C10H16 terpenes.   Naphtha mixtures containing C9 - C11 alkanes or alkyl-substituted benzenes could cause interferences with the turpentine mixture.

The method has a working range of 9 to 360 ppm (50 to 2000 mg/m³). 

NOTE: This is Method S88 in a revised format.
