1 Introduction
1.1 Instrument description
The 887 Professional UV/VIS Detector is within the 850 Professional
IC family an independent instrument for the photometric determination of
light absorbing substances in the UV/VIS range.
It can be used as an alternative UV/VIS detector with any instrument of
the 850 Professional IC, the 881 Compact IC pro, and the 882 Compact IC
plus families.
The 887 Professional UV/VIS Detector is operated with MagIC Net™
Software. It is connected via a USB connection to a PC on which
MagIC Net™ is installed. The software automatically recognizes the instrument and checks its functional readiness. MagIC Net™ controls and monitors the instrument, evaluates the measured data and administers it in a
database.
1 Introduction
Additional information on operating MagIC Net™ can be found in the
document "Tutorial for MagIC Net™" or in the online help.
1.2 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 samples. The usage of the 887 Professional UV/VIS Detector therefore requires
that the user has basic knowledge and experience in the handling of toxic
and caustic substances. Knowledge with respect to the application of the
fire prevention measures prescribed for laboratories is also mandatory.

1.4 Safety instructions
￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭
Mains voltage
Warning
An incorrect mains voltage can damage the instrument.
Only operate this instrument with a mains voltage specified for it (see
rear panel of the instrument).
Protection against electrostatic charges
Warning
Electronic components are sensitive to electrostatic charges and can be
destroyed by discharges.
Always pull the mains cable out of the mains connection socket before
connecting or disconnecting electrical appliances on the rear panel of
the instrument.
1.4.3 Tubing and capillary connections
Caution
Leaks in tubing and capillary connections are a safety risk. Tighten all
connections well by hand. Avoid applying excessive force to tubing
connections. 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 mandatory.
1.4.4 Flammable solvents and chemicals
Warning
All relevant safety measures are to be observed when working with
flammable solvents and chemicals.
￭ Set up the instrument in a well-ventilated location (e.g. laboratory
flue).
￭ Keep all sources of flame far from the workplace.
￭ Clean up spilled fluids and solids immediately.
￭ Follow the safety instructions of the chemical manufacturer.

3.1 Setting up the instrument
3 Installation
3.1 Setting up the instrument
3.1.1 Packaging
The instrument is supplied in highly protective special packaging together
with the separately packed accessories. Keep this packaging, as only this
ensures safe transportation of the instrument.
3.1.2 Checks
Immediately after receipt, check whether the shipment has arrived complete and without damage by comparing it with the delivery note.
3.1.3 Location
The instrument has been developed for operation indoors and may not be
used in explosive environments.
￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭
Place the instrument in a location of the laboratory which is suitable for
operation, free of vibrations, protected from corrosive atmosphere, and
contamination by chemicals.
The instrument should be protected against excessive temperature fluctuations and direct sunlight.
3.2 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. To build such a system, you will need a
887 Professional UV/VIS Detector and the following instruments:
￭ any 850 Professional IC instrument, or
any 881 Compact IC pro instrument, or
882 Compact IC plus
￭ the 886 Professional Thermostat / Reactor
￭ optionally: a 872 Extension Module for sample preparation
￭ optionally, if the PCR reagent is pumped with a high pressure pump: a
Metrosep BP 1 Guard/2.0 (6.1015.100) backpressure column.
￭￭￭￭￭￭￭￭

An IC system with photometric detection and post column reaction can
be set up in in various combinations (see Figure 3, page 9).

Note for proposed setup
If you want to place the instruments in two stacks, we recommend you
protect the instruments of the second stack and also order the following
accessories:
￭ 6.2061.100 Bottle holder (ProfIC)
￭ 6.2061.110 Base tray with sensor for Professional IC systems
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.

￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭
3.3 Mounting base tray and bottle holder (optional)
The 6.2061.110 base tray and 6.2061.100 bottle holder protect IC instruments from dust, dirt and leaking fluids. If more than one instrument of
the Professional IC family is used, these can be set up in one or more
stacks. We recommend that a bottle holder and a base tray be mounted
on/below each stack of instruments.
Bottle holder and base tray must be removed or mounted every time one
of the following instruments is mounted on or under an 850 Professional
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 instrument under the IC instrument. Proceed as follows:
