The Partisol 2000
i
can be configured to sample a wide range of ambient
PM sizes, including TSP, PM
10
, PM
2.5
, and PM
1
. It is important that the
proper filter material be used when collecting different PM size ranges as
certain filter materials are required for different types of sampling.
The only filter media currently approved by the U.S. EPA for reference
method sampling of PM
2.5
and PM
coarse
fractions is a 47 mm diameter, 2
m pore-size Teflon filter. These filters can be purchased from Thermo
Fisher Scientific in the following form:
PTFE (Teflon) filters, 2.0 m pore size, box of 50 (10-002322-0050)
You may use other filters or materials for other types of sampling,
depending upon local regulations. For example, the U.S. EPA allows the
