Auto-collector Software
Brechtel provides software to control the Auto-collector. A screenshot of the Auto-collector
software is shown in figure 27. Refer to the operation section of this manual for detailed
instructions on operating the Auto-collector.
6.8 Pre-Impactor
If purchased as an option with the PILS, the impactor prevents particles larger than a
certain maximum size from entering the instrument sample air flow inlet. If large par-
ticles are not prevented from entering the instrument, they may create a potentially in-
terfering chemical artifact by overwhelming measured species concentrations.
IMPORTANT: It is highly recommended that the PILS always be operated with either a
1 or 2.5 micrometer size-cut impactor on the PILS inlet.
Note that, BRECHTEL DOES NOT supply a differential pressure sensor to read the pres-
sure drop across the impactor. Refer to more detailed instructions in the user manual
that came with the impactor for more information.
6.9 Vapor Denuders
Inorganic and organic vapor denuders may be purchased as an option to the PILS and are
used to remove potentially interfering gasses from the airflow before the sample air en-
ters the PILS condensation chamber. Shown in figure 15, the denuders are off-the-shelf
