2.2.6 Micro-Fuel Cell "Class"

Analytical Instruments manufactures Micro-Fuel Cells with a variety of
characteristics to give the best possible performance for any given applica-
tion. Each unique cell type is given an alphanumeric designation consistent
with its application. This designation is its "class."
If the sample gas contains 10 % or more hydrogen and/or helium, only
"clamp" cells are used. These Micro-Fuel cells are identified by the suffix -C
added to the cell class number.
The class L-2C cell is for general purpose, and hydrogen/helium ser-
vice, trace oxygen analysis, where the slightly larger size of the cell is ac-
ceptable to obtain a longer life than is available with the standard size cell.
Nominal output in air is 0.5 mA, and 90 % response time is 7 s.
Expected life is 12 months.
