ESCRIPTION
The InnovaPrep ACD-200 Bobcat, shown in Figure
1.1, is a lightweight, portable, dry filter air sampler
with a unique patented rapid filter elution system.
The Bobcat aerosol collector takes up little more
than one-quarter of a cubic foot, has an internal
battery, built-in tripod, and can run continuously at
200 liters per minute for up to 12 hours. The system
has a built-in, omni-directional aerosol inlet, easy to
read status display, and a built-in handle. The
system is equipped with a mass flow sensor that
allows for consistent sampling rates throughout the
collection cycle. It can be operated in four
programmable run modes that allow the user to balance collection rate
with battery life. The system is easy to use and operators can be trained
in a little as 10 minutes. Installation of the filter cassettes and the
controls can be manipulated with gloved hands, while wearing personal
protective equipment such as military-style nuclear/biological/chemical
(NBC) protective suits.
Following aerosol collection, the user snaps the sample cup onto the
filter to remove it from the collector, then snaps the elutor onto the
filter. To extract the captured particles from the filter, a canister
containing the elution fluid is pressed into the elutor. The elution fluid is
released from the canister and turns to foam as it flushes the filter. The
wet foam passes through the interstitial spaces of the filter to efficiently
extract captured particles. Sample elution takes approximately 5
seconds and produces 6 to 7 milliliters of liquid sample. The foam
quickly collapses back to a liquid in the sample cup, making it available
for sample processing and analysis.
