3.3.2.5. Zero Scrubber and Internal Span Source (IZS) (OPT 50G)

The 9110T nitrogen oxides analyzer can also be equipped with an internal NO2 span gas generator and calibration valve option. This option package is intended for applications where there is a need for frequent automated calibration checks without access to an external source of span gas.

This valve package includes:

A 2-stage external scrubber for producing zero air.

50% Purafil Chemisorbant® (for conversion of NO NO2).

50% charcoal (for removal of the NO2).

A heated enclosure for a NO2 permeation tube.

This option package DOES NOT contain an actual permeation tube. See Section 1.4 (Options 52B and 52G) for information on specifying the correct permeation tube for each application.

A special desorber that removes all HNO3 from the calibration gas stream.

One additional gas inlet port (ZERO AIR).

One additional gas outlet port (FROM DRYER).

Two internal valves for switching between the sample gas inlet and the output of the zero/span subsystem.
