Abstract
A liquid leakage decision unit includes a leak sensor value storage part that stores a leak sensor value that is based on the intensity of a signal received from a gas sensor; a difference calculation part that, when the signal is received from the gas sensor, calculates, as a difference value, a value obtained by subtracting a previous leak sensor value stored in the leak sensor value storage part from a current leak sensor value; and a liquid leakage detection part that compares the difference value calculated by the difference calculation part with a preset threshold, thereby to detect liquid leakage in the column oven.
