Gas Module

General Troubleshooting

Check that the argon and nitrogen (if used) connections are secure and that the supply pressures from both the argon and nitrogen supplies are correct.
The nebulizer pressure is too high. Ensure the nebulizer and makeup (if required) gas line is connected to the gas port on the front of the instrument and that the tubing is not kinked or damaged. Replace if necessary.
Check the nebulizer for any blockages. Clean the nebulizer or replace it if required.
Check that the spray chamber drain is not blocked.
The nebulizer pressure is too low. Ensure the nebulizer and makeup (if required) gas line is connected to the gas port on the instrument and that the tubing is not damaged. Replace it if necessary.
Check that the tubing to the nebulizer is not damaged and that all fittings are tight and not leaking. Clean the nebulizer or replace it if required.
Check that the tubing is securely connected to the solution tubing from the peristaltic pump and is not leaking.
Check the optics purge gas connection and supply pressure.
Replace the optics purge gas filter.
Check the gas fitting on the ICP-OES and on the gas supply for leaks.
Check for kinks in the gas tubing. Replace the tubing if required.
