Our pumps are relied upon in ambient, source and portable devices for environmental sample collection and analysis. The Southwest Indianapolis Air Toxics Study (2010) details a project in which the Indiana Department of Environmental Management (IDEM), the U.S. Environmental Protection Agency (EPA), the City of Indianapolis and a diverse group of stakeholders teamed up to conduct an air-toxics study in Indianapolis, Indiana. This region was identified to be an area of potential risk for cancer risk from air toxics.
A KNF pump (customized from a N 86 standard) was was used to enable the analysis of the total non-methane organic carbon (TNMOC) concentration of ambient air. The U.S. Environmental Protection Agency (EPA) set a National Ambient Air Quality Standard (NAAQS) for the criteria pollutant, ozone. In areas of the country where the standard for ozone is being exceeded, additional measurements of the ambient non–methane organic compound (NMOC) concentration are needed to assist the affected states in developing revised ozone control strategies. Measurements of ambient NMOC are important to the control of volatile organic compounds (VOCs) that are precursors to atmospheric ozone and are the subject of many studies into the negative effects that VOCs have on atmospheric ozone and “the expanding hole in the ozone layer”.
Therefore, a reliable pump was essential for the collection of air samples with potentially harmful toxics. Simultaneously, it was critical for the pump to collect samples in a manner that didn’t change or contaminate the samples. Our KNF pumps, known for their reliability and chemical inertness, are ideally situated for this type of application. Additionally, their extremely high gas tightness allows for the accurate and complete collection of media without the risk of sample loss, dilution, or contamination
