Non-Nitric Acid Liner and Plug Conditioning
1. Use hot soapy water and foam brush to clean the liners and plugs. Rinse thoroughly with DI water and allow to
dry completely before use.
NOTE
Micro 90 Cleaner® liquid detergent works well on Teflon. Avoid detergents that contain ingredients that
could cause potential contamination such as Na and P. Avoid abrasive cleansers and stiff brushes which
can scratch the Teflon surface.
2. Place 0.25 g ± 0.05 g of your sample into each liner. Never add sample or liquid to liner with sleeve in place.
WARNING
Proper precautions must be taken to avoid contact with reagents or reagent vapors. Protective gear should
be worn as outlined in the user’s safety program for hazardous materials and the reagent manufacturer’s
safety data sheet. Refer to these guidelines for proper handling and disposal of the reagents.
3. Add 10 mL of the digestion acid to each liner. Use the acid to rinse the inside of the liner to ensure that the
sample is in the base of the liner.
4. Wait 15 minutes to allow pre-digestion.
5. Assemble and torque each vessel. See “Vessel Assembly” for detailed instructions.
6. Place the turntable into the MARS 6 cavity and symmetrically distribute vessels. See “Turntable Setup” and
"Vessel Distribution" for detailed instructions.
7. Select and load the “Easy Prep Clean” method from the One Touch directory.
8. Close the instrument door and run the preprogrammed “Plant Material” method.
9. After completion of the method, permit the vessels to cool in the automated sequence until the vessels cool to
below 80 ºC.
WARNING
Allow vessels to cool below 80 ºC before opening the microwave door.
To prevent the possibility of severe burns, ensure that gloves and protective gear as outlined in your safety
program are worn.
10. Remove the vessel assemblies from the turntable. See "Vessel Removal" for detailed instructions.
11. Rinse the liners and plugs with deionized water.
NOTE
When using HCl, if a dark ring appears in liner, use hot soapy water and foam brush to clean. Rinse
thoroughly with DI water and allow to dry completely before use.
