A Purge and Trap-Gas Chromatographic Method for Determination of Chlorofluorocarbons in Seawater
A purge and trap system was developed for the determination of chlorofluorocarbons (CFCs) in seawater. The optimum conditions were as follows: trap temperature of -60 degrees C, purge time of 8 min, purge flow rate of 20 mL/min, desorption time of 1.5 min, desorption temperature of about 130 degrees...
