Impact/Purpose:
The Environmental Technology Verification (ETV) Program has been established by the EPA to verify the performance characteristics of innovative environmental technology across all media and to report this objective information to permitters, buyers, and users of the technology, thus substantially accelerating the entrance of new environmental technologies into the marketplace. Verification organizations oversee and report verification activities based on testing and quality assurance protocols developed with input from major stakeholders and customer groups associated with the technology area. Effective verifications of monitoring technologies are needed to assess environmental quality and to supply cost and performance data to select the most appropriate technology for that assessment.
Description:
This is a verification report statement that describes the verification test which was conducted over a period of approximately 30 days (April 5 to May 7, 2013) and involved the continuous operation of duplicate Model 4 OC-EC analyzers at the Battelle Columbus Operations Special Support Site (BCS3) in Columbus, Ohio. Sunset Laboratory’s semi-continuous Model 4 OC-EC Field Analyzer has been developed as a field deployable alternative to integrated filter collection with subsequent laboratory analysis. This instrument can provide time-resolved analyses of OC and EC in airborne particulate matter (PM) on a semi-continuous basis, with OC-EC results comparable to the recognized NIOSH Method 5040 and other thermal optical carbon aerosol methods currently in use.
