I am getting background noise, what should I do?
There are 2 possible causes for this background noise:
A/ Leaks in the RI IOTA 2 cell
Remove the exchanger unit.
Check for tank leaks
If these leaks persist, replace the cell.
B/ Air bubble in the RI IOTA 2 cell
Ensure that the pressure at the column head is stable, that the column is equilibrated and that there are no leaks from the connectors.
