  • Page 9: Introduction

    1 Introduction 1 Introduction Instrument description The 889 IC Sample Center is a robust Autosampler for high sample through- put, optimized for the challenges of the modern analytic laboratory. Its greatest advantages are speed and small sample volumes. Special features: Control of syringes with high resolution.

  • Page 10: Instrument Components

    This instrument is suitable for processing chemicals and flammable samples. The usage of the 889 IC Sample Center therefore requires that the user has basic knowledge and experience in the handling of toxic and caustic sub- stances. Knowledge with respect to the application of the fire prevention measures prescribed for laboratories is also mandatory.

  • Page 11: Safety Instructions

    To maintain this state and ensure non-hazardous operation of the instrument, the following instructions must be observed carefully. 1.3.2 Electrical safety The electrical safety when working with the instrument is ensured as part of the international standard IEC 61010. ￭￭￭￭￭￭￭￭ 889 IC Sample Center...
  • Page 12 ￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭ 1.3 Safety instructions Warning Only personnel qualified by Metrohm are authorized to carry out service work on electronic components. Warning Never open the housing of the instrument. The instrument could be dam- aged by this. There is also a risk of serious injury if live components are touched.

  • Page 13: Tubing And Capillary Connections

    Personnel safety Warning Wear protective goggles and working clothes suitable for laboratory work while operating the 889 IC Sample Center. It is also advisable to wear gloves when caustic liquids are used or in situations where glass vessels could break.

    Grip the device underneath with both hands when you are transporting it. Always hold the device in an upright position. Before you switch on the 889 IC Sample Center, allow the device to stand for at least one hour in order to adapt to the room temperature.

  • Page 22: Connecting A Computer

    Objects placed on the device could also impair the cooling output. Objects can be placed at the sides of the 889 IC Sample Center. If an object is placed on only one side, then a minimum clearance of 5 cm must be maintained.

    MagIC Net™ . Connecting pump and column The 889 IC Sample Center is supplied with the necessary mounted hose and capillary connections. Connect the high pressure pump and the separation columns to the still unoccupied ports 1 and 6 on the injection valve with one suitable PEEK capillary each (6.1831.010).

Fill the washing bottle with isopropanol. Warning Do not use any saline or buffer solutions. Crystals could block or damage the entire system.

  • Page 27: Functioning

    The syringe aspirates the sample out of the sample vessel and into the sample loop. The buffer loop between the syringe and the injection valve prevents the contamination of the syringe. Washing solution is required in order to: ￭￭￭￭￭￭￭￭ 889 IC Sample Center...
