Blanket Air: Water pumped, hydrocarbon free,
Zero Gas: Water pumped, hydrocarbon free
Span Gas:
The span gas contains a known amount of methane impurity. The
span gas must be certified as to its methane equivalent impurity.
IMPORTANT: For the best possible results, zero and span
gases that are representative of the parent (or
background) gas should always be used.
This is particularly true in applications where the analyzer is being used
to analyze a number of different samples with varying concentrations of
oxygen. The geometry and temperature of the flame will be somewhat
dependent on the oxygen content of the sample. Alterations in the flame
configuration will lead to differences in output readings. For the best possible
results, TAI recommends that zero and span gases representative of each of
these samples be used to standardize the analyzer.
