Remove the EC100 enclosure desiccant from the plastic bag and put it
back in the mesh pocket of the enclosure.

6.3.1 Flow
The EC155 has a small sample cell volume (5.9 cm
3
) to give good frequency
response at a relatively low flow rate. The sample cell residence time is 59 ms
for a sample flow of 6 LPM (assumes vortex bypass flow is 2 LPM, and total
flow to the pump is a nominal 8 LPM). The CPEC200 pump module is
designed to provide this flow for the EC155 but other user-supplied pumps
may be used. There is no specific limitation to the flow rate that may be used
with the EC155 but the sample cell pressure must be considered.
6.3.2 Pressure
The EC155 is designed to be used near ambient pressure, but it will not be
damaged by operation under vacuum. The EC155 vortex sample cell includes
an absolute pressure sensor to measure sample cell pressure, whereas the
original EC155 sample cell included a differential pressure sensor to measure
