Page 5: Safety Notations
Safety Notations Safety Notations This manual uses three safety alert words at points in the documentation where the user should be aware of potential hazards. The safety alerts are shown in color-coded boxes. The three words–NOTE, CAUTION, and WARNING–indicate differing levels of observation or action as described below: NOTE A NOTE is intended to provide emphasis of procedures that may be misinterpreted or overlooked, or to otherwise clarify confusing situations. -
Page 6: Introduction
CEM Corporation for assistance. Depending on the instrument configuration, this Manual should be used in conjunction with the MARS 6 manual (P/N 600284) or MARS 6 iWave Manual (P/N 600832). If your MARS instrument is not listed, contact your CEM Representative for assistance. -
Page 7: Important Safeguards
Important Safeguards Microwave sample preparation imposes a unique set of safety considerations beyond the basics of good laboratory practice. Additional Safeguards for the MARS 6 instrument are included in the MARS 6 manual (P/N 600284) or MARS 6 iWave manual (P/N 600832). General guidelines for safe operation of the EasyPrep vessel series are presented below and all specific safety messages are located throughout the manual. -
Page 8: Vessel Safeguards
Vessel Safeguards • Only use consumables, accessories, vessels and vessel components purchased directly from CEM or through its authorized dealer network. • The standard cover is recommended for applications using primarily HNO , HF, H , and H • The Premium cover is recommended for non-HF applications where HCl and aqua regia are heavily used. -

Page 17: New Liner And Cover Conditioning
All new liners and covers should be conditioned as a set prior to being put into service. The break-in procedure is used to condition the Teflon® to ensure a proper seal. CEM recommends conditioning the covers and liners based on the acid type that will be used: HNO , HCl, H , HF. -
Page 18: Non-Nitric Acid Liner And Cover Conditioning
Non-Nitric Acid Liner and Cover Conditioning 1. Use hot soapy water and foam brush to clean the liners and covers. 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 . -
Page 19: Perform A Digestion
Perform a Digestion In addition to the instructions below, view the “EasyPrep Vessels” video located in the MARS software (System Settings -> Video -> EasyPrep Vessels.) The EasyPrep Vessels have multiple configurations available for the Standard and Premium covers: MARS 6 EasyPrep Temperature Only, MARS 6 EasyPrep Temperature and Pressure, MARS 6 EasyPrep Plus Temperature only, MARS 6 EasyPrep Plus Temperature and Pressure, and EasyPrep Plus iWave. - Page 20 CAUTION Do not use water to dilute the acid(s) greater than 25% when running over 220 ºC or to add volume before digestion. This can cause uneven heating of vessels. 5. Wait 15 minutes to allow pre-digestion. 6. If applicable, assemble the Easy Prep Plus Control Cover. 6.1.
- Page 21 NOTE Invert the vessel sleeves after every test to help maintain uniformity of the liner and sleeves. 9. Place the load disc on the cover with the tab on the disc facing downward so that it fits into the center notch of the cover.
- Page 22 • The control vessel requires the taller frame (except EasyPrep with temperature control only) • The standard vessels and EasyPrep with temperature control only require the shorter frame. • If the cover has pressure control, select the "Easy Prep Plus" control frame and position the pressure connector so it passes through the frame and aligns toward the outside of the frame.
- Page 23 Vessel torquing is critical to optimize controlled venting of the system and for the integrity of the vessel. Over or under torquing may lead to sealing issues. If any issue is noted, contact CEM Corporation. 15. Verify the vent hole alignment. If a vessel vents, the acid should not get on the frame or other vessels. If nec- essary, loosen the screw and realign the vent hole.

Page 24: Turntable Setup
Turntable Setup 1. If applicable, load the control vessel in the "Control Vessel" or "1" position of the turntable. 1.1. If the control vessel has pressure control, connect the ESP-1500+ pressure connector and tighten until finger tight. If the ESP-1500+ pressure option is not available, tighten the nut until finger tight. 1.2. - Page 25 CAUTION If resistance is felt when trying to insert probe, ensure that the thermowell is not broken inside the Teflon cover. The sharp edges of any break can restrict the movement of the probe. The "MTS-300 High Temp" (P/N 281461) Fiber Optic probe is required for applications running 250 ºC or greater in temperature.

Load the turntable into the instrument by aligning the Control Vessel or position “1” with the front of the instru- ment. Ensure turntable is seated down on drive lug. Perform a Digestion...
- Page 27 WARNING The fully loaded turntable without vessels may be heavy (>20 pounds (9 kg)). Use caution when lifting and loading into the cavity. Do not place fingers beneath the turntable when placing in the cavity. 6. If applicable, connect the pressure sensor to the right side wall of the MARS 6 cavity. 6.1.
