Title:
METHOD FOR DETERMINING SUSPENDED PARTICULATE MATTER, SAMPLING TUBE AND SAMPLING KIT FOR USE IN DETERMINING SUSPENDED PARTICULATE MATTER
Document Type and Number:
WIPO Patent Application WO/2001/092862
Kind Code:
A1
Abstract:
A method for determining a suspended particulate matter which comprises passing a gas containing a suspended particulate matter through a capturing material, to render the capturing material to adsorb the suspended particulate matter in the gas, measuring the amount of the atomic species and molecular species having a lone electron pair contained in the suspended particulate matter adsorbed by the capturing material using the electron spin resonance method, and determining the amount of the suspended particulate matter in the gas, based on the measured amount of the atomic species and molecular species having a lone electron pair; and a sampling tube and a sampling kit for use in the method. The method can be used for measuring an amount of a suspended particulate matter contained in an exhaust emission gas with accuracy and with ease.
