APPLICABILITY: This method was developed to give better desorption than obtainable with carbon disulfide extraction of the charcoal. This method can be used in paint and resin manufacturing plants.
INTERFERENCES: None reported. Alternate columns, e.g., 4 m 10% SP-2100/0.1% Carbowax 1500 on Supelcoport 100/120 or DB-1 fused silica capillary may be used.
OTHER METHODS: This method combines and replaces Methods S10, S12, S13, S15 and S16 [1].
