2 Introduction
Introduction
About the EasyPrep™ Vessel Series
The EasyPrep, EasyPrep Plus, and EasyPrep iWave®vessels are designed for microwave digestion in a MARS 6™.
These rugged high performance vessels are good for preparing a wide variety of difcult to digest organic and
inorganic materials. These include many types of oils and polymers, ceramics and catalysts, pigments & toner,
coal, alpha alumina, or digestion of large organic samples like food and plant/animal tissues when lower detection
limits are critical. The EasyPrep vessel series are easy to assemble vessels with moderate throughput. Preinstalled
One Touch™methods take the guesswork out of method creation and sample preparation.
This manual is intended for use by both novice and experienced users for the operation and maintenance of the
vessel. Additional information, including but not limited to: training notes and videos, application notes, software
updates, and parts can be viewed on CEM’s website at https://cem.com.
CEM recommends updating the MARS 6 and MARS 6 iWave system to software version 1.49 (or greater). Contact
CEM Corporation for assistance.
Depending on the instrument conguration, 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.
Read and fully understand all documentation before operating the instrument.
For assistance regarding vessel inserts, view the 35 mL Quartz Vessel Insert Manual (P/N 600742 and P/N
600744), 3mL or 7mL Teon Insert Manual (P/N 600769) or contact CEM Corporation.
3Important 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 specic safety messages are located throughout the manual.
Proper precautions must be taken to avoid contact with acids or acid vapors. Protective gear should be worn as
outlined in the user’s safety program for hazardous materials and the acid manufacturer’s safety data sheet. Refer
to these guidelines for proper handling and disposal of the acids.

Sample Preparation Safeguards
• Do not use water to dilute the acid(s) greater than 25% when running over 210 ºC or to add volume before
digestion. This can cause uneven heating of vessels.
• Run similar sample types with the same acid(s) and acid volume in each vessel.
• Optimal Sample Volume is 10mL and will result in more even heating.
• Minimum volume for the MARS 6 cavity is 10 mL of acid or 50 mL of water.
• Maximum sample weight varies per sample type. See "Operating Parameters" for weights.
• Never run an acid blank in the control vessel.
• Acid blanks cannot account for more than 25% of turntable when mixed with samples.
• Acid blanks cannot be run with samples when acid mixtures are > 50% hydrouoric acid. Acid blanks must be
run separately.
4 Important 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 HNO3, HF, H2SO4, and H3PO4.
• The Premium cover is recommended for non-HF applications where HCl and aqua regia are heavily used.
• All vessel components must be dry prior to use.
• Always condition new liners and covers.
• Ensure vessels are assembled properly.
• Invert sleeves after every run to extend lifetime and promote better sealing & even heating.
• Slide liner into the end of the sleeve with most resistance felt if unsure which side was previously used.
• CEM recommends using a high temperature pen to mark sleeves for a visual reference.
• Bake out liners to remove residual HNO3& NOxgases
• See "Liner Bake-Out Procedure" for details.
• Bake out liners if TempGuard™is triggered.
• Do not cool any of the vessel components in the freezer.
• The fully loaded turntable without sample may be heavy (>20 pounds (9 kg)). Use caution when lifting and
loading into the cavity. Do not place ngers beneath the turntable when placing in the cavity.
Microwave Safeguards
• Always use the TempGuard feature in the method for software versions < 1.48. TempGuard is preset and non-
adjustable in version 1.49 (or greater).
• Set the TempGuard limit at 30 °C > control temperature if control temperature is < 230 °C.
• Set the TempGuard limit at 20 °C > control temperature if control temperature is > 230 °C.
• Limit TempGuard to 250 °C for digestion of organics with HNO3 (primarily).
• Limit TempGuard to 300 °C for H3PO4/H2SO4(primarily) applications.
• Limit control temperature of organics with HNO3to 230 °C.
• For non-iWave congurations, Duotemp must always be ON.
• Always use the Max Power Monitor and set the alarm time for 5 minutes.
• Maximum programmable temperature is 310 °C.
• Maximum temperature varies per acid. See "Operating Parameters" for temperatures.
• Maximum programmable Hold Time is 59 minutes.
• Maximum recommended Hold Time is 30 minutes.
• Observe the positioning and balance of the turntable.
• If applicable, ensure the pressure line and ber optic probe are connected, in position and properly aligned.
• If a run is stopped or paused for more than 30 seconds during the digestion, do not restart the method with hot
vessels.
• Allow vessels to cool for a minimum of 15 minutes.
• Vent vessels and reseal.
• Restart method from the beginning.
• Allow vessels to cool for a minimum of 15 minutes before opening the microwave door.
5Important Safeguards
Compounds Unsuitable for Closed Vessel Microwave Digestion
WARNING
CEM will not be responsible for damage to equipment and facilities or personal injuries resulting from
microwave digestion of samples that are deemed unsuitable for closed vessel microwave digestion.
Acid decomposition of certain chemical compounds or types of samples constitutes unreasonable, hazardous
misuse of CEM microwave digestion systems. The classes of compounds listed below are unsuitable for closed
vessel microwave digestion because they are highly reactive with oxidizing acids and/or may become nitrated and
potentially explosive. Absence of a particular chemical compound from this list does not imply microwave acid
decomposition of such a sample is safe under all conditions.
• Explosives (TNT, Nitrocellulose, etc.)
• Propellants (Hydrazine, Ammonium Perchlorate, etc.)
• Pyrophoric chemicals
• Hypergolic mixtures (Nitric Acid and Phenol, Nitric Acid and Triethylamine, Nitric Acid and Acetone, etc.)
• Animal Fats (Esters of glycerol capable of nitration and the formation of nitroglycerin or other nitrated organic
compounds)
• Aviation Fuels (JP-1, etc.)
• Acetylides
• Glycols (Ethylene Glycol, Propylene Glycol, etc.)
• Perchlorates (Ammonium, Potassium, etc.)
• Ethers (Cellosolve - Ethylene Glycol Phenyl Ether, etc.)
• Lacquers
• Alkanes (Butane, Hexane, etc.)
• Ketones (Acetone, Methyl Ethyl Ketone, etc.) and Alcohols (Methanol, etc.)
