HEATED LIQUID SAMPLING PROBE FOR AND AUTOMATED SAMPLING APPARATUS

摘要

2083486 9217761 PCTABS00016 A heated liquid sampling probe (10) for an automated sampling apparatus includes a sampling tube (22) for drawing up a volume of liquid from a reservoir (50). The tube is connectable to an automated sampling apparatus including a chassis (20). A capacitance (Cp) exists between the sampling tube and the chassis. An electrical heater (12) is arranged for heating the tube and a volume of liquid contained therein. The electrical heater increases the capacitance between the tube and the chassis by an amount (CH). A capacitance lowering mechanism (60) is provided for lowering the increase in capacitance due to the heater.
