Abstract
Provided are a suspended particulate matter measurement apparatus capable of automatically measuring a nitrate ion content and a sulfate ion content in the atmosphere, and a suspended particulate matter measurement method using the same. The suspended particulate matter measurement apparatus includes a filter, suction part, extraction part, measurement part, and a recording part. The suction part suctions air in the atmosphere at a constant flow rate to cause particulate matter contained therein to be adsorbed onto the filter. The extraction part extracts components of the particulate matter adsorbed onto the filter, by dissolving the particulate matter into a solvent, and collects a resultant solution. The measurement part measures at least one of a nitrate ion content and a sulfate ion content in the solution collected by the extraction part, and outputs the measurement result. The recording part records the measurement result outputted from the measurement part.
