PM 2.5 Equipment at Greenville, ME

Exposed PM Filter Known Sample Area =11.86 cm2

Known Sample Time ~ 1,440 min Known Sample Flow Rate ~ 16.7 L/min

Known Sample Volume ~ 24.0 m3

Tare Weight – Gross Weight = Net Filter Weight Gain (mg)

Net Gain / Sample Volume = Sample Concentration (mg/m3)

XRF Results expressed in ng/cm2

(XRF ng/cm2) x 11.86 cm2 x (1mg/1000ng) x (1/Sample Volume m3 ) = XRF mg/m3
