IMMERSION HEATER FOR SPARGE VESSEL

摘要

A sparge vessel (12) having a liquid sample (13) is heated with an immersion heater (10). The use of the immersion heater (10) in the sparge vessel (12) more completely purges any analytes in the liquid sample (13) to a sorbent trap. A thermocouple (23) may be used to help the immersion heater (10) maintain the liquid sample (13) at a desired temperature between 70 and 85 degrees C.
