TSI Instruments in Laser Printer Emissions Research

Talk of the town? Laser printers indeed

October 2, 2007-  A recently publicized study led by Professor Lidia Morawska shows average particle number concentration inside a test office is five times higher during working hours than non-working hours. The research team investigated emissions from 62 printers and found 17 to be high emitters. Notably, the leading Australian research team relied on TSI instruments such as Scanning Mobility Particle Sizer, Condensation Particle Counters, P-Trak and DustTrak monitors to investigate particle number and PM2.5 emission characteristics from office laser printers and photocopiers. The results are described in new research published in ES&T (DOI:10.1021/es063049z).

TSI instruments have been part of studies worldwide investigating indoor air quality problems. As the strive for clean air continues, TSI is proud to serve this important area of research.
