Filter Handling and Exchange
This section explains how to perform the initial inspection and the
equilibrium and weighing (before and after sampling) of the 47 mm filters
used in the Partisol 2025i and 2025i-D Samplers. This section also
describes how to insert and remove the filter cassette magazines in the
Sampler, and calculate the 24-hour mass concentration average, as found in
the U.S. EPA 2.12 Quality Assurance Handbook, Volume II Part II Section
7: Filter Preparation and Analysis, Section 8 Field Operation and Section
11: Calculations, Validation and Reporting of PM

Note If you are operating your Sampler in cold weather conditions, where
the temperature will reach less than -30 °C, you will need to install a metal
piston friction ring (part number 36-005570) in your supply filter cassette
magazines. Refer to "Installing the Metal Piston Friction
