Marin-5 Operator’s Manual
Troubleshooting the Marin-5
3 Temperature controller stops illuminating.
• Thermal safety switch tripped due to excessive temperature. Heat
controller or solid-state relay is defective. Contact CETAC
Customer Service.
Solution Drainage Problems
1 Liquid waste is not removed from the Marin-5.
• Adjust tension on drain pump to improve liquid waste flow.
• Check for wear or damage to drain pump tubing. Replace tubing if
necessary.
2 Drain pump will not operate.
• Contact CETAC Customer Service.
Nebulizer / Plasma Problems
1 Poor and/or unstable aerosol generation.
• Insufficient nebulizer gas flow or pressure. The Argon
nebulizer gas flow should be in a 0.5 - 1.1 L/min range. If such a
flow range cannot be achieved, there may be insufficient nebulizer
gas pressure. Increase inlet pressure (not to exceed 100 psi or
700kPa.). Normal operating pressure for the Marin-5 is 40 psi
argon pressure. If the ICP-AES or ICP-MS cannot achieve 40 psi,
alternative plumbing may be required.
• Uptake line may be obstructed or damaged. Replace the
nebulizer uptake line.
• Leak in the nebulizer gas line. Inspect the nebulizer gas line to
make certain that all connections are correct and leak-free. If the
line is leaking, repair with appropriate tubing.
