Using the Marin-5
• Peristaltic Pump Tubing
The peristaltic pump tubing that drains the Marin-5 should be replaced
whenever the tubing becomes flat or damaged due to tension shoe
pressure. See Chapter 6, “Maintaining the Marin-5 System” for further
details (p. 6-9).
Startup Procedure
1 If the Marin-5 has been turned off for an extended period of
time, turn on the AC power switch and allow the HEATER and
COOLER temperatures to reach operating values and stabilize
(approximately 5-10 minutes).
2 Ignite the plasma according to standard operating procedures
for the ICP-AES or ICP-MS instrument. Re-adjust Marin-5
operating parameters to the optimized settings. If the system
has not been optimized, see Chapter 4 “Verifying Installation.”
3 The Marin-5 System is now ready to use.
Shutdown Procedure
1 Aqueous Analysis: Aspirate dilute nitric acid (2% HNO3 v/v) for
approximately 5-10 minutes to provide a thorough spray
chamber rinse. Follow the acid-rinse by aspirating deionized
water for approximately 3-5 minutes.
2 Remove the sample uptake line from the deionized water and
aspirate the solution remaining in the sample line. It is
important to dry the sample uptake line prior to shutting down
the system.
3 Shut down the ICP-AES or ICP-MS using the procedures
recommended by the manufacturer.
