Title:
SYSTEM FOR MEASURING CARBON COMPONENT CONTAINED IN PARTICULATE MATTER
Document Type and Number:
WIPO Patent Application WO/2014/162614
Kind Code:
A1
Abstract:
In this system, the carbon component of atmospheric particulate matter (PM2.5) is measured by: heating a sample in a first oven under such conditions as to fractionate the carbon component into carbon fractions; completely converting each carbon fraction into carbon dioxide gas in a second oven; and then measuring the amount of carbon dioxide gas in the carbon fraction precisely. In the system, the problem that a TCD detector cannot measure a low-concentration fraction is solved by using a combustion gas in a non-diluted state, though a combustion gas diluted 150-fold is used in a conventional elemental analyzer. Thus, the present invention develops an international standard instrument in which one standard sample is used and which enables simple standardized measuring acceptable to The International System of Units (SI).
