Important Safeguards

General guidelines for safe operation of the EDGE system are presented below and all specific safety messages
are located throughout the manual.
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. Dispose of all waste in accordance with
all applicable local, state, and federal health and safety recommendations.

Instrument Safeguards

• Service can only be performed by an authorized CEM service technician. The system must be disconnected
from power supply prior to servicing.
• Do not tamper with the EDGE, including actions such as removing any components of the housing or
manually trying to move the automation components.
• The exhaust hose must be connected and draw at least 30.5 CFM at the point of connection at all times as
it is essential for removing harmful gases away from the EDGE instrument. Vapors should be vented into a
fume hood by means of the exhaust hose only.
• NEVER place hands or any object into the automation area from the time "Start" is selected until the system
is idle.
• Do not place hands or objects in the actuator (vessel chamber) area unless instructed to do so.
• Only load or unload rack when the EDGE is in the idle state or instructed to do so.
• If any damage to the instrument is noted, do not attempt instrument operation.
• Vessel Chamber area may be hot.
• Use only CEM specified consumables and accessories.

Sample Preparation Safeguards

• Q-Cups and Q-discs must be purchased directly from CEM Corporation or through its authorized dealer
network.
• 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.
• Do not fill sample above the outer band of the Q-Cup
• For plastic samples, always stay below the melting point.
• The EDGE is not compatible with any strong acids or bases.

Heating Safeguards

• Ensure that the pressure of the solvent at the maximum set temperature is less than 200 psi.
• Observe Preheat Temperature - the temperature the chamber heats to prior to running each extraction.
• If the method temperature is 100 °C or above, a preheat temperature of 100 °C is recommended.
• If the method temperature is less than 100 °C, the preheat temperature should be the method
temperature.
• The preheat temperature cannot be set lower than room temperature.
• A preheat temperature higher than the set point of your methods will lead to a system error.
• Preheat temperature can be changed in settings.
