"Tutorial for MagIC Net™" or in the online help. Intended use The 887 Professional UV/VIS Detector is used as an independent detector with various analysis instruments of the Metrohm line of instruments. This instrument is suitable for processing chemicals and flammable sam- ples.
1.3.1 Modifications since previous version This manual substitutes its previous version 8.887.8002EN, it includes the following changes: The conditions for the adjustment of lamp settings are specified more ■...
The electrical safety when working with the instrument is ensured as part of the international standard IEC 61010. 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 damaged by this.
Damaged tubing ends lead to leakage. Appropriate tools can be used to loosen connections. Check the connections regularly for leakage. If the instrument is used mainly in unattended operation, then weekly inspections are manda- tory. ■■■■■■■■ 887 Professional UV/VIS Detector...
The correct disposal of your old instrument will help to prevent negative effects on the environment and public health. More details about the disposal of your old instrument can be obtained from your local authorities, from waste disposal companies or from your local dealer. ■■■■■■■■ 887 Professional UV/VIS Detector...

Proposed setup The 887 Professional UV/VIS Detector can be used as a detector with the instruments of the 850 Professional IC, the 881 Compact IC pro, and the 882 Compact IC plus family. For many applications with photometric detection, a post column reaction with the 886 Professional Thermostat / Reactor (2.886.0110) is required.
■ If you want to stack a 881 Compact IC pro or an 882 Compact IC plus instrument with a 887 Professional UV/VIS Detector, the 886 Professional Thermostat / Reactor and/or a 872 Extension Module, you will require the 6.2061.120 System Connector to adapt the different support surfaces.
850 Profes- sional IC instrument: One or more 872 Extension Module. ■ An 886 Professional Thermostat / Reactor. ■ An 887 Professional UV/VIS Detector. ■ or another instrument of the same support surface. ■ 3.3.1 Removing / mounting the base tray The base tray must be removed, in case you want to place another instru- ment under the IC instrument.

There are no loose parts in the instrument. ■ The instrument is lying on it side, and the bottom surface is visible. ■ To mount the base tray, you need a 3 mm hexagon key (6.2621.100). ■■■■■■■■ 887 Professional UV/VIS Detector...
The instrument is switched off. ■ The bottle holder is cleared. ■ Drainage tubing is disconnected from the drainage tubing connection ■ of the bottle holder. To remove the bottle holder, you need a 3 mm hexagon key (6.2621.100). ■■■■■■■■ 887 Professional UV/VIS Detector...

Mounting the bottle holder Before you can mount the bottle holder, the following preconditions must be met: The instrument is switched off. ■ To mount the bottle holder, you need a 3 mm hexagon key (6.2621.100). ■■■■■■■■ 887 Professional UV/VIS Detector...

In order to keep the dead volume as low as possible, capillary connec- tions should generally be as short as possible. NOTICE For an improved overview, capillary and tubing connections can be bun- dled with the 6.1815.010 spiral band. ■■■■■■■■ 887 Professional UV/VIS Detector...
Page 24
Creating dead volume free capillary connections To create dead volume free capillary connections, proceed as follows: 1 Slide the pressure screw over the capillary. Ensure that the capillary protrudes 1–2 mm from the tip of the pressure screw. ■■■■■■■■ 887 Professional UV/VIS Detector...

Page 26
In order to fix the flow-through cell in the correct position, both knurled screws must be tightened symmetrically and with constant force. Any tilting, twisting or canting of the flow-through cell influences the light incidence and thus the measuring results. ■■■■■■■■ 887 Professional UV/VIS Detector...
Slide the pressure screw over the detector inlet capillary such that ■ a small part of the capillary is visible at the top. Screw the detector outlet capillary to the detector outlet with the ■ pressure screw. ■■■■■■■■ 887 Professional UV/VIS Detector...
The instrument must be switched off when connecting the PC. 1 Connecting the USB cable Connect the PC connection socket of the instrument to a USB con- nector of the computer via the 6.2151.020 USB cable. ■■■■■■■■ 887 Professional UV/VIS Detector...

■■■■■■■■■■■■■■■■■■■■■■ 5 Operation The instrument is operated via MagIC Net™ software only. Additional information on operating MagIC Net™ can be found in the document "Tutorial for MagIC Net™" or in the online help. ■■■■■■■■ 887 Professional UV/VIS Detector...
In such cases, the Metrohm Service must be informed. Spillages of chemicals and solvents should be cleaned up immediately. In particular, the plug connections on the rear panel of the instrument (espe- cially the mains plug) should be protected from contamination.
Door CAUTION The door is made of PMMA (poly(methyl methacrylate)). It must never be cleaned with abrasive media or solvents. CAUTION Never hold the instrument by the door when lifting or moving it. ■■■■■■■■ 887 Professional UV/VIS Detector...
