Lead monitoring equipment

Tuesday, 28 July, 2009 | Supplied by: Ecotech Pty Ltd



In October 2008, the US EPA tightened its National Ambient Air Quality Standards (NAAQS) for lead (Pb) from 1.5 µg/m3 to 0.15 µg/m3, measured as total suspended particulates (TSP). This change has meant a 10-fold decrease in acceptable lead levels and thus, the accuracy of monitoring equipment is even more important.

Ecotech meets this stringent new monitoring requirement with its US EPA-approved HiVol 3000 (RFPS-0706-162) and also with its MegaVol 3000.

In order to accurately monitor these low levels of lead, the HiVol 3000 air sampler is fitted with volumetric flow control including inputs from local conditions - ie, local air temperature and pressure. The exhaust from the HiVol 3000 is also directed away from the sampling point by at least 4 m to ensure no recirculation of sample air.

The MegaVol 3000 sampler, designed for the European air monitoring community, uses a flow rate of 150 m3/h and has been designed to obtain low concentration (trace) detection limits for a number of target compounds and elements including: lead and all types of heavy metals; radioactive particles; organochlorine pesticides; polychlorinated biphenyls (PCB); polynuclear aromatic hydrocarbons (PAH); and dioxins/furans.
