Teledyne API Model 200AU NOX Analyzer Instruction Manual, 02293, Rev. F

Zero/Span valves have 3 operational states:

1.Sample mode. Here both valves are un-energized and sample gas passes through the sample/cal valve and into the analyzer for analysis.

2.Zero mode. The sample/cal valve is energized to the cal mode. The zero/span valve is un- energized in the zero mode, thus allowing zero gas to be admitted through the rear panel bulkhead fitting into the analyzer.

3.Span mode. The sample/cal and the zero/span valves are both energized and in the cal mode. With both valves on, span gas is admitted through a rear panel bulkhead fitting into the analyzer.

Zero air and span gas inlets should supply their respective gases in excess of the 1000 cc/min demand of the Analyzer. Supply and vent lines should be of sufficient length and diameter to prevent back diffusion and pressure effects. See Figure 2-3 for fitting location and tubing recommendations.

Zero air for this instrument should have less than 1 ppt (.001 ppb) NO and have various interferent gas concentrations such that they produce less than 1 ppt total interferent. We recommend a tank of Ultra Zero Air commonly used in gas chromatographic applications as a reliable and constant source of zero air. Another source of zero air is the Model 701 zero air module.
