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 com-
plete 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 and free of vibrations and which provides protection against
corrosive atmosphere and contamination by chemicals.
The instrument should be protected against excessive temperature fluctu-
ations and direct sunlight.
The distance between the rear of the instrument and the wall must be
large enough to ensure air circulation on the cooling plate.
3.2 Setup configurations
The 944 Professional UV/VIS Detector Vario can be used as a detector
with the instruments of the 940 Professional IC Vario and 930 Compact IC
Flex family. For many applications with photometric detection, a post-col-
umn derivatization with the 943 Professional Thermostat / Reactor Vario
(2.943.0110) is required. To build such a system, you will need a 944 Pro-
fessional UV/VIS Detector Vario and the following instruments:
￭ any 940 Professional IC Vario, or
any 930 Compact IC Flex
￭ a 943 Professional Thermostat / Reactor Vario
￭ optionally: a 942 Extension Module Vario for sample preparation
￭ optionally, if the reagent is pumped with a high-pressure pump: a Met-
rosep BP 1 Guard/2.0 backpressure column (6.1015.100)
An IC system with photometric detection and post-column derivatization
can be set up in in various configurations.
