VOC Speciation

Recent NCASI technical activity in this area seeks to evaluate the use of OTM-026, in conjunction with modified Method 25A to develop better estimates of speciated VOC emissions from wood products sources. This activity commenced in the late 1990s when the forest products industry initiated a multi-year research study on VOC emissions. The objectives of this NCASI investigation were to (1) determine the individual VOCs that comprised most of the mass of VOC emissions in significant VOC emission sources, (2) develop practical measurement approaches to measure the key VOCs in these sources, and (3) develop procedures that could be used to provide reasonable estimates of the total mass of VOC emissions from the sources.
