New Technique Solves IAQ Mystery In Office Building
Richard Fogarty, president of New Trend Environmental Services Ltd., loves a good mystery. He especially likes the ones where the suspects are concealed and the clues are invisible. His favorites have endings where building owners solve tough indoor air quality (IAQ) problems.
Fogarty is a modern-day IAQ sleuth. Instead of a magnifying glass, he uses a P-Trak™ Ultrafine Particle Counter to solve difficult IAQ problems. Manufactured by TSI Incorporated (St. Paul, MN), this instrument counts ultrafine particles or UFPs (those less than 0.1 micrometer in diameter) to track indoor pollutants to their source. Once a source is identified, building management can control or eliminate the source and stop related IAQ complaints.
