Sample flow
Normal operation of the Model 3050-RM analyzer uses an internal bypass,
which increases the response speed of the system. However, the 3050-RM
is capable of running in a gas-saver mode as well, which allows the ana-
lyzer to run on a sample volume of approximately 150 SCCM.
There are four separate sample paths in the 3050-RM analyzer manifold.

The first is a simple bypass that allows for an increased flowrate of
sample gas. This means that when you open the bypass valve (SV1),
you reduce the time required to equilibrate all portions of the sample
system that exist upstream of the bypass valve. A capillary tube,
located immediately downstream of SV1 (the coil shape in Figure 1-2),
limits the flow rate to approximately 1 standard liter per minute (the
exact value of the bypass flow is a function of the inlet pressure to the
analyzer).
