Ozone Precursor Analyzer Systems

Now incorporating the new PerkinElmer TurboMatrix™ Thermal Desorbers.

In the United States, the Clean Air Act of 1970 gave the Environmental Protection Agency (EPA) responsibility for maintaining clean air for health and welfare. The six parameters routinely measured in ambient air were expanded in 1990 to include volatile organic compounds (VOCs). Volatile organic compounds, carbonyl compounds and NOx are generally regarded as precursors to ground-level ozone formation in urban and industrial areas and may be present in the atmosphere at low part per billion (ppb) concentrations. These measurements are implemented through a program known as Photochemical Assessment Monitoring Stations (PAMS). Similar recommendations by other regulatory agencies have also been made around the globe.

PerkinElmer, in conjunction with the U.S. EPA, originally developed an analyzer and methodology to collect and measure C2-C12 hydrocarbons automatically, in the field, without the use of liquid cryogen. This established method, which has been successfully employed for many years with PerkinElmer Ozone Precursor Analyzers, now includes fully integrated technologies incorporating PPC in both the Clarus® GC and the TurboMatrix Thermal Desorber components of the system.
