4.2.8 Ozone Generator

Because of the instability of ozone, it is necessary to generate this gas inside the analyzer. The
ozone generation module consists of a high voltage AC supply and silent discharge tube and
permeation type air drier. A complete description of its function and service requirements can be
found in Section 9.3.6.
Lethal voltages present inside ozone generator.
The dry air supply for the ozone generator uses a membrane drier to supply air with a dew point
o
of 0 C or less. The exhaust side of the membrane is connected to the vacuum manifold at the
rear of the instrument.
Normal room air contains enough water vapor to damage the generator and components
downstream. To prevent damage, the generator will be turned ON after 30 min following a cold
start. Otherwise, the starting of the generator will follow the table below:

4.2.9 Molydbenum Converter

The molybdenum converter is a stainless steel cartridge containing molybdenum chips heated to
315° C. The converter's function is to reduce nitrogen dioxide NO
temperature control for this module is done by the computer.
