  • Page 5: Introduction

    INTRODUCTION The combined PL-ELS 2100/2100 Ice Service Manual is designed for use by personnel who have had training and are experienced in servicing this type of equipment. Whilst the PL-ELS 2100/2100 Ice has been designed for easy repair, there are potential hazards associated with servicing this instrument.

  • Page 6: Safety

    Always ensure that the detector is disconnected from the mains power when the side panel is opened. The PL-ELS 2100/2100 Ice has a safety bar at the powe r input socket that prevents the detector’s side panel being opened whe n the powe r cable is still connected.

  • Page 7: Installation

     The mass flow controller is not calibrated for use with gases other than Air or Nitrogen  For operation with other inert gases contact Polymer Laboratories for advice. Gas flow: up to 3.25 SLM @ 60 psi @ 25ƒC Pressure operating range: 60 – 100 psi (4-6.7 bar) Maximum Pressure: 100 psi (6.7 bar)

  • Page 8: Unpacking The Detector

    Examine the shipping carton for visible signs of exterior damage. Unpack the instrument and examine for transit damage. Check that all items on the packing list are included. Notify your local distributor or Polymer Laboratories of any damage or missing items. Packing list ...

  • Page 9: Fluid Connection

    Ensure the exhaust hose has an upward slope from the PL-ELS 2100/2100 Ice so that any condensed solvent is collected in the waste bottle at the front of the unit and to prevent it accumulating in the tubing.

  • Page 10: Serial Rs232 Connector

    The serial RS232 connector provides a 24bit (10Hz) digital output for connection to a chromatographic acquisition device. The PL-ELS 2100/2100 Ice ca n be controlled from a PC using the RS232 interface and the PL- ELS 2100/2100 Ice graphical control software from Polymer Laboratories Ltd. Refer to the control software on- line manual for operating instructions.

  • Page 11: Installing The Detector

    Turn on the source gas to a pressure of about 60-100 psi. The gas will not flow though the detector until the instrument in set to RUN mode.  Switch on the PL-ELS 2100/2100 Ice, and select a suitable method.  Start heating by selecting RUN mode using the arrow keys on the front keypad.

  • Page 13: Optimising Detector Performance

    OPTIMISING DETECTOR PERFORMANCE General Considerations The PL-ELS 2100/2100 Ice instrument should be thought of as a detector like any other designed for liquid chromatography. The main distinguishing feature is the ability to evaporate the solvent from the column eluent. Therefore, normal system set-up precautions should be remembered when starting to use the instrument.

  • Page 14: Nebuliser Temperature

    The PL-ELS 2100/2100 Ice can be operated at sub-ambient temperatures to improve the detection of semi- volatile compounds. In aqueous solvents, baseline noise may become too excessive at temperatures <15ƒC. However, for organic solvents, the baseline can be controlled down to 10ƒC, provided the gas flow is increased to compensate.

  • Page 15: Overview Of Detector's Operation Modes

    Standby Mode The STANDBY mode is the “ground state” of the PL-ELS 2100/2100 Ice instrument, which is initiated automatically after power on. In this mode of operation the heaters are off, and the gas manifold valve is closed.

  • Page 16: Troubleshooting

    TROUBLESHOOTING If a problem is encountered Polymer Laboratories advises a system test be performed via the PL- ELS 2100/2100 Ice PC control software to ensure that the detector is working correctly. If there is an error or fault, please refer to the following table. If you follow the recommended course of action and the result is not satisfactory, then please direct the matter to Polymer Laboratories or your local distributor.
