Routine Maintenance
A routine maintenance protocol is vital for the long-term operation of the iPrep vessels. For maintenance
instructions for MARS 6 instrument, see the MARS 6 manual (PN 600832.)
After Every Use
• Clean all vessel components. See “Vessel Cleaning” section of this manual.
• Wipe inside of MARS 6 cavity, including the iWave sensors, with a lint free damp cloth.
Monthly
• Inspect liners - Liners should be smooth, white, and do not flare at top or bottom.
• Inspect sleeves. Discard Sleeves that have lightened in color or turned white, or are flared at the ends.
Annually
Contact CEM Service Department, local CEM subsidiary or distributor for information on CEM Service contracts.
Bake-out Procedure
As needed: The bake out procedure can be used to remove residual acid vapors and other trapped gases from the
Teflon® vessel liner material. Trapped gases can potentially cause uneven heating between new and used liners.
The bake out procedure can be used to remove residual NOx gases from liners following digestion with HNO
3
that
may interfere in subsequent runs. This procedure has been successfully used to remove sulfur contamination from
the Teflon liners following digestion of samples with high sulfur content.
