Thermo Scientific 1405-DF ambient particulate monitor

July 2013 Analytical Instrumentation & Environmental Monitoring

The Thermo Scientific 1405-DF monitor is composed of two filter dynamics measurement systems (FDMS) and two TEOM mass sensors housed in a single cabinet with network-ready configuration that includes the control system with touch screen user interface.

The system is designed to provide representative short and long term readings of the ambient PM concentration, even in the presence of volatile materials. Conventional PM monitoring approaches do not account for the rapid loss that can occur with collection on a filter while sampling ambient PM. The 1405-DF monitor overcomes this challenge by automatically generating mass concentration measurements that account for both non-volatile and volatile PM-10, PM-2.5 and PM-coarse components. The system’s default data output consists of a running 1-hour and 24-hour average mass concentration updated every 6 minutes and on the hour respectively. The monitor computes a 1-hour FDMS base and reference mass concentrations updated every 6 minutes. Users can select additional averaging times from 30 minutes to 23 hours.

The 1405-DF provides a self-referencing, NIST-traceable true mass measurement using proven high reliability TEOM technology. The system differentiates itself from other PM measurement methods by utilising a direct mass measurement that is not subject to measurement uncertainties found in surrogate techniques such as beta attenuation, light scattering and pressure drop.
