Particulate measurement apparatus and particulate measurement system

A particulate measurement apparatus for controlling a particulate sensor which measures the amount of particulates contained in a gas under measurement and which comprises an ion generation section for generating ions by means of corona discharge, an electrification chamber for electrifying at least a portion of the particulates contained in the gas under measurement using the ions generated in the ion generation section, a trapping section for trapping at least a portion of the ions generated by the ion generation section but not used for electrifying the particulates, and an auxiliary electrode section including an auxiliary electrode maintained at a potential which repulses the unused ions and which assists in the trapping of the unused ions at the trapping section, the particulate measurement apparatus comprising:

• a voltage application section which applies a voltage to the auxiliary electrode through a voltage application path, the applied voltage assisting the trapping of the ions at the trapping section;
• a current detection section which detects an auxiliary electrode current flowing to the voltage application path;
• and
• a state determination section which determines at least one of a state of the particulate sensor and a state of the voltage application path based on the auxiliary electrode current detected by the current detection section.
