    Abstract: The present invention relates to a method for measuring condensable particulate matters formed from exhaust gas of an internal combustion engine, including the steps of sucking exhaust gas from the internal combustion engine; diluting the sucked exhaust gas to simulate it to atmospheric condition; a first measurement step of branching some of the exhaust gas of the atmospheric condition and measuring particulate matters including condensable particulate matters and filterable particulate matters; a second measurement step of branching the rest of the exhaust gas of the atmospheric condition to remove the condensable particulate matters and measuring the particulate matters including only the filterable particulate matters; and comparing the first measurement step and the second measurement step to calculate an amount of the condensable particulate matters in the exhaust gas of the atmospheric condition.
