Introduction
Overview
1-2 Partisol 2025i and Partisol 2025i-D Instruction Manual
The Samplers are designed to be installed at an outdoor sampling location
without additional protection from the elements. They draw a particulate-
laden ambient air stream through a sample inlet, either size-selective or TSP
(total suspended particulate) depending on the Sampler model, and then
through 47 mm diameter filter(s). A variety of filter materials are available in
this size. A built-in pump provides the vacuum required to pull the air flow
through a sample filter and a mass flow controller.
Filter exchanges are performed using pneumatic pressure from the sample
pump, and does not involve any special electro-mechanical components,
belts, or motors. New filter cassettes from the supply magazine are pushed up
and rightward into the sampling position, while the completed sample
cassette(s) is moved to the storage magazine. The supply and storage
magazines are supplied with covers to seal off filter cassettes when not used
for sampling.
