This study aimed to develop relationships between particulate matter (PM) concentrations
obtained from a direct-reading instrument to those from a gravimetric method. TSI DustTrak
II Aerosol Monitors (Model 8530), a direct-reading instrument for PM10 and PM2.5
measurement, together with personal air pumps connected to a Sensidyne cyclone and a SKC
Personal Environmental Monitor (PEM) for gravimetric PM10 and PM2.5 measurements
respectively were deployed in the Faculty of Science building, Silpakorn University, Nakhon
Pathom, Thailand. Comparison of the results from each instrument indicated that PM10 and
PM2.5 concentrations obtained from the TSI DustTrak were higher. Etc...
