To report volumes in standard terms, the user must ensure that the standard
temperature and standard pressure parameters are set to their proper values.
In many countries, standard volumes are defined in terms of 760 mmHg
pressure and 25 °C temperature. Flow volumes referenced internally by the
Sampler to 0 °C are converted to standard conditions using the following
computation:
The Partisol 2000
i
-D Dichotomous Air Sampler collects both
coarse
and
fine
particulate matter (PM) on two separate filters.
Coarse
PM is defined as
particles with a diameter between 2.5 and 10 microns.
Fine
PM is defined as
particles with a diameter of less than 2.5 microns. The sampler consists of
two sample flows directed through two 47 mm filters — a low flow (1.67
L/min) for coarse particulate and a high flow (15 L/min) for fine particulate
(
Figure 1–3
).
The U.S. EPA prescribes the use of Teflon filter material for reference PM
2.5
and PM
coarse
sampling, and for U.S. EPA sampling Teflon filters are sinstalled
in both sample positions in the Partisol 2000
i
-D. For other types of sampling
a range of other materials can be used in the 47 mm format, incuding TX40
(Teflon-coated glass fiber) and quartz fiber filters. Other materials are
available for special applications.
