The IR cells have normally base lines adjusted to about 8V and the peak comes
down during analysis, respectively during IR absorption by the measuring gas.
In case of golden paths, although we intensively clean them with solvents and
heated up to over 500°C for one day or more, in the first couple of months after
being in operation, the base line may goes up, which means that the paths become
more reflective during this period. Therefore, the base lines of golden paths should
be initially set rather at 5 or 6 volts instead of 8 volts. In the first couple of months
the base lines go up, but the growing slows down and growing contamination
finally causes the base line to start coming down.
The initial base line adjustment at 5 to 6 volts, prevents the maximum base line
value from reaching 9.5V, where the error message “Check base line” appears.
Note that this message is just a warning. The analyzer is not prevented from
carrying out further analyses. As long as the base line remains below 10V, the
results are correct.
If a base line is below -9.5V an adjustment should be done as advised above. If
this is not possible, then most probably there is a fault or a very strong
contamination. In case of contamination, all cells available should have very low
voltages, even negative ones.
If all available cells are below -9.5V there is most probably a fault like no rotating
chopper motor or a faulty infrared source.

The flow rate is electronically controlled; therefore there should be no significant
variation from the set value.
