6.3 PILS Chassis

The PILS may be configured for laboratory, bench top usage, or it may be mounted in a
standard instrument rack. Normally, the PILS sample air flow is controlled by maintain-
ing critical flow through a critical orifice built into the PILS droplet impactor exit air flow
fitting. A detailed view of the front panel of the PILS chassis is shown in figure 5. The
photo shows the droplet impactor on the left, the round debubbler between the droplet
impactor and peristaltic pump in the middle, and the two temperature controllers on
the right side of the front panel. The peristaltic pump speed control potentiometer is
directly below the steam heater temperature controller.
