Abstract
A heated liquid sampling probe for an automated sampling apparatus includes a sampling tube for drawing up a volume of liquid. The tube is connectable to an automated sampling apparatus including a chassis. A capacitance exists between the sampling tube and the chassis. An electrical heater 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. A capacitance lowering mechanism is provided for lowering the increase in capacitance due to the heater.
