Trace Oxygen Analyzer Installation
Teledyne Analytical Instruments 15
During the installation and/or replacement of the MFC, the
membrane surface MUST ALWAYS FACE DOWNWARD, and the
contact side of the membrane, must be placed FIRST into Analysis Unit.
The reason for proper installation/replacement is, if any bubble that
develops as the electrolyte dries out it will be directed by gravity away
from the membrane.
To install or replace the Micro-Fuel Cell, follow the procedures in
Chapter 5, Maintenance .
