2.3 Sample System

The sample system delivers gases to the Micro-Fuel Cell sensor
from the analyzer rear panel inlet. Depending on the mode of operation
either sample or calibration gas is delivered.
The Model 3000RS-P sample system is designed and fabricated to
ensure that the oxygen concentration of the gas is not altered as it travels
through the sample system. The sample encounters almost no dead
space. This minimizes residual gas pockets that can interfere with
percent analysis.
The sample system for the standard instrument incorporates 1/8
inch tube fittings for sample inlet and outlet connections at the rear
panel. For metric system installations, 6 mm adapters are available for
instruments to be used if required. The sample or calibration gas flows
through a digital flow sensor which reports the flow downstream from
the cell. Figure 2-5 shows the internal piping layout for the standard
model.
