  • Page 5: Operating Precautions

    This instrument utilizes high voltages and microwave radiation. Only those trained in repair and maintenance of high voltage and microwave power systems should perform instrument service and repair. Use of the Discover instrument in any manner not specified by CEM Corporation could render the instrument operation unsafe for the operator.

  • Page 6: Introduction

    Introduction The CEM Focused Microwave Discover® SP-D Clinical System is designed to enhance the ability to perform acid digestions under controlled conditions on a laboratory scale. It accommodates 4 mL and 10 mL vessels for reactions performed at elevated temperatures and pressures.

  • Page 7: Instrument Description

    Never modify the attenuator access port or insert metallic objects such as wire into the port. Serious microwave leakage and/or electrical shock may result. The access port of the Discover SP-D Clinical is electrically grounded to the microwave cavity and is designed to prevent leakage of microwave energy.

    5. Plug the power cord into the wall outlet. 6. To set up the air regulator: a. Splice the tubing supplied by CEM in half. b. Install one length of the tubing into the left side of the Discover by pushing in on the tubing until resistance is felt.

  • Page 13: Computer Installation (Optional)

    The ActiVent (pressure device) will return to the home position once the Login screen appears. Remove the 10mL shipping device. Note: Do not discard the 10mL shipping device. It will be required if returning the system to CEM Corporation for service. Computer Installation (optional) Connect one end of the Ethernet cable to one of the Ethernet ports located at the rear of the Discover.
  • Page 14 Using the pull-down menu, select the proper name and enter the appropriate password. Select “OK.” Synergy will automatically load the user’s preferences and connect to the Discover and Explorer modules during the login process. Select “Network Setup.” The following screen will appear. Select the Discover icon.

  • Page 15: User Login

    User Login Before system operation can begin, the user is required to log into the Discover system. The Discover software is designed to permit use by three types of users: Standard, Administrator and Guest. The Discover is originally equipped with an “Administrator,” “User” and “Guest”. The “Administrator” login cannot be deleted. Refer to instrument setup for instructions to create administrative, guest and standard user profiles.

  • Page 16: Microwave Tips

    Microwave Tips Cover all solids in the reaction vessel with liquid. Never exceed the maximum working volume of the vial. Always use a stir bar that adequately mixes the reaction contents in the microwave. Reactions can be performed under an inert atmosphere. Try performing the reaction at higher concentrations.

  • Page 17: Closed Vessel Extraction

    Place the cap onto the vial. WARNING The Discover SP-D Clinical is usable only with CEM supplied 4mL or 10mL reaction vessels and caps for sealed reactions. Install the appropriate attenuator assembly with the large slot positioned toward the back of the instrument.

  • Page 18: Vessel Removal

    Remove the Vessel Once the vessel is properly cooled, the ActiVent will release the vessel and “Complete” will appear on the Display. If the ActiVent does not automatically release the reaction vessel, the pressure (or temperature) is above the release limit. A message will appear indicating the current temperature and pressure value. Cool the reaction vessel completely and manually release the ActiVent.

  • Page 19: Load, Save, And Create A New Method

    Load, Save, and Create a New Method The “Load, Save, and Create a New Method” screen allows all users to create new methods, save them to the Discover data base and Load (recall) the methods at a later time. From this screen, the user can also recall data from a reaction previously run on the Discover system.

  • Page 20: Standard Control

    Standard The Standard Control is a fast and simple reaction method. The user programs A temperature control point and A run time (time held at the specified temperature). All other method parameters are controlled by the instrument defaults. All method parameters can be edited with the Discover hotkeys.
  • Page 21 The “Times at SP” is the maximum number of times a reaction will vent during the assigned ramp and hold time. However, this parameter can be adjusted based on specific reaction conditions. For a typical reaction, 5 vents are recommended. CAUTION If the reaction temperature exceeds the acid boiling point and too many venting actions are performed, the vial could become dry and superheat.

  • Page 22: Ramp To Temperature Control

    NOTE: The ActiVent feature is not required for the Dynamic Control Option. It allows the Discover SP-D Clinical System to release unwanted gaseous byproducts from the reaction to prevent over pressurization and vial failure from gaseous buildup.

Enter the desired method parameters using the “arrow” keys to navigate between power, time, temperature, pressure stirring and PreMix.

  • Page 24: Save Method

    Pressure ‘P’ – 0 – 500PSI • Stirring Speed – Low, Medium, High (Medium is recommended). Stirring is required for digestions. • PreMix Time – 0-120 seconds • Press the Discover key to activate and program parameters for the ActiVent® option and select the vessel type. NOTE: The ActiVent feature is REQUIRED for the Ramp to Temperature Control Option.

  • Page 25: Load Method

    The Load Method option gives the user the ability to recall a method previously saved under their user profile or that of another user saved on the same Discover SP-D Clinical System. Methods can also be transferred from one system to another using the USB flash drive supplied with the Discover SP.
