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
application. Each unique cell type is given an alphanumeric designation
consistent with its application. This designation is its “class.”
2.2.6.1 Hydrogen and/or Helium Service
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.
2.2.6.2 Class L-2C/B-2 Cell
The class L-2C/B-2 cell is for general purpose, and hydrogen/helium
service, trace oxygen analysis, where the slightly larger size of the cell is
acceptable 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.
