GRANTS PASS, Oregon - October 26, 2000 - Met One Instruments is pleased to announce that it will be supplying the majority of particulate monitoring samplers for the EPA's TRENDS Sites around the United States. Particulate speciation samplers are used to gather PM2.5 particulate samples for further analysis to determine concentrations of a wide array of chemical species all thought to have an adverse effect on the public health. These chemical species include nitrates, sulfates, elemental and organic carbon, and a variety of anions and cations. One goal of establishing the TRENDS network is to establish benchmark data for the concentration of these chemical compounds throughout the United States and to provide a database for environmental and healthcare professionals.

"We have been working closely with the US-EPA, and are pleased with the results", remarked Dr. David Gobeli, Technical Director. Of the 54 nationwide sites to be equipped with the particulate mass speciation samplers, at least 40 of them will have the Met One Instruments SASS Speciation Sampler deployed. According to Frank Lawson, Marketing Director, "we are now focused on delivering the high quality product, and providing the service and support necessary to exceed the expectations of the US-EPA and the state and municipal air pollution districts using the equipment."

Dr. Gobeli went on to add "there is no question that the combination of portability, ease of use, and excellent technical support from our staff in Grants Pass made the Met One sampler an undeniable winner. We carefully studied the US-EPA requirements, and worked with the day-to-day users of the equipment, to become the favored supplier." Met One Instruments, under contract with the US-EPA, has been developing aerosol sampling equipment suitable for collecting PM2.5 (particle mass for particles up to 2.5 microns in diameter) samples.

Established in 1989, Met One Instruments is a privately-held, leading worldwide supplier of electronic instrumentation used in meteorological weather systems, and ambient air pollution monitoring.
