摘要： The present invention provides a method for determining suspended particulate matter accurately and conveniently, a sampling tube for sampling the suspended particulate matter, and a sampling kit for using the collection of the suspended particulate materials. In the present invention, the exhaust emission is passed through a collection material to adsorb the suspended particulate matter in the exhaust emission on it. Then, the amounts of the atoms or the molecular species having unpaired electrons contained in the suspended particulate matter adsorbed on the collection material are determined by using Electron Spin Resonance spectroscopy. The amounts of the suspended particulate matter contained in the exhaust emission may be accurately and conveniently obtained, based on the amounts of the atoms or the molecular species determined above.
