EOHSI

In order to provide researchers at EOHSI and the broader university community with state-of-the-art human exposure facilities, recent support provided by Dr. Michael Pazzani, Rutgers Vice President for Research and Economic Development, was used to upgrade the monitoring equipment used in EOHSI’s Controlled Environmental Facility (CEF). Funding provided by the Office of the Vice President for Research and Economic Development (OVPR) enabled EOHSI to procure the following new instrumentation:

• Electrospray Aerosol Generator, Model 3480 (TSI, Inc.)
• MicroAeth® Personal Exposure Monitor for Black Carbon, Model AE51 (AethLabs)
• Photometric Ozone Analyzer, Model 49i (Thermo Scientific)
• Nanoparticle Surface Area Monitor, Model 3550 (TSI, Inc.)
• Carbon Monoxide Monitor, Model T15n (Langan Products, Inc.)
• NI Labview 2010 Software Platform (National Instruments)

Some potential uses of these instruments are described below:

The electrospray aerosol generator (Model 3480, TSI, Inc.) uses the electrospray method to convert a solution or suspension to monodisperse aerosols in the size range of 2 to 100 nanometers. The personal exposure monitor for black carbon (Model AE51, AethLabs) is a pocket-sized black carbon aerosol monitor which can provide real-time information about the mass concentration of black carbon in the atmosphere. The Model 49i Photometric Ozone Analyzer (Thermo Scientific) utilizes UV Photometric technology to measure the amount of ozone in the air from ppb levels up to 200 ppm. The nanoparticle surface area monitor (Model 3550, TSI, Inc.) can measure the human lung-deposited surface area of particles (reported as ?m2/cm3) corresponding to tracheobronchial (TB) and alveolar (A) regions of the lung (in the size range from 10 to 1000 nm).
