Abstract: An artifact free inert filter medium for collection of organic particles is a fibrous material is developed that can be formed into filters used in ambient and indoor air sampling equipment for subsequent laboratory chemical analysis by one of several thermal optical or thermal analysis methods for the determination of organic carbon (OC), elemental carbon (EC), pyrolysis carbon (PC), and total carbon (TC, sum of OC+EC), carbon fractions determined by thermal or thermal-optical analysis methods (OC1, OC2, OC3, OC4, PC, EC1, EC2, EC3) as well can be analyzed in the laboratory for individual organic species by a range of thermal analysis and or extraction/analysis methods.
