With the introduction of the Clean Air Act and its amendments in 1990 by the Environmental Protection Agency under Title II Emission Standards for Moving Sources, Part A - Motor Vehicle Emission and Fuel Standards, Section 211 Regulation of Fuels - (h) Reid Vapor Pressure Requirements, it has become unlawful to sell, offer for sale, dispense, supply, offer for supply, transport, or introduce into commerce gasoline with a Reid Vapor Pressure in excess of 9.0 pounds per square inch (psi) during the high ozone season.


Using a simply constructed, yet rugged, measurement chamber and sample delivery method, operational cost savings have been realized without complicating the analytical system.  The Reid Bapor Pressure Analyzer demonstrates the optimization of the fluidics paths by employing components and materials that allow for a rapid measurement cycle without limiting accuracy, repeatability or reliability.
