5.1 Overview
The uCEM Analyzer Module requires very little maintenance during normal
operation.
Occasionally, the detector's reaction chamber and sapphire window may
require cleaning, refer to Section 5.7.
White crystal deposits on the windows of the reaction chamber and plugging
of capillaries and vent are usually due to sample contaminates such as
ammonia reacting with the high ozone levels and NO components. To
eliminate the contaminates, the sampling system should be reworked or a
preventive maintenance program developed (if dropout is not excessive).
Another source of crystalline formation is contaminated air.
Several components may require replacement. These are discussed in the
following sections.
