1.6.6 Sample gas connection (see Figure 1.4)

A critical flow orifice is used to control the sample flow. The orifice is a precision- drilled sapphire jewel protected by a 20 micron sintered filter. The critical flow orifice never needs adjustment and maintains precise flow control as long as the ratio of the up- stream to down-stream pressures is greater than .53 (sonic flow conditions).

1.6.6 Sample gas connection (see Figure 1.4)

A 2 m section of 1/4" O.D. PTFE tubing is needed to connect the sample source to the Analyzer.

NOTE

USE PTFE, GLASS, STAINLESS STEEL OR

NON-REACTIVE MATERIALS FOR SAMPLE GAS

CONNECTIONS.

NOTE

USE VENT LINE WHEN SAMPLING FROM

PRESSURIZED MANIFOLDS - SAMPLE PRESSURE

SHOULD NOT EXCEED ±1" H2O

1.6.7 Zero/span valve connections (see Figure 1.4)

Zero air and span gas manifolds should supply their respective gases in excess of 800cc/min demand of the Analyzer. The manifold should be vented to the outside atmosphere and be of sufficient length and diameter to prevent back diffusion and pressure effects.

Adequate zero air can be supplied by the M300 using the IZS option or by using a commercial calibrator.
