6 Intended Use
AZURA V 2.1S User Manual, V6860, Version 2.2
Intended Use
Note: Only use the device for applications that fall within the range of the
intended use. Otherwise, the protective and safety equipment of the device
could fail.
Description
2-position valves are used in the HPLC to bring in the sample from the sample
loop in the pumps high pressure flow, so that the sample is transported to the
column. The sample is brought into the sample loop with a syringe or a feed
pump. Multiposition valves serve for fractionating, eluent selection, or sample
selection.
2-position valves have 6 ports and 3 channels (6P/3C), multiposition valves
have 1 channel always.
Operating Ranges
Among others, the device can be used for analytical or purification tasks.
Device Overview
Various types of valves with different operating modes allow the use of these
valves for a variety of applications. It is important that valve drive and valve are
compatible.
You can mount additional manual valves to an optional mounting bracket that
can be fixed with screws on the AZURA modules or other devices. Find further
information on our website www.knauer.net.
Valves and Valve Drives
Valves and valve drives are completely assembled and tested when they leave
the factory.

and serial number.
External devices can be connected to the valve drive in three different ways:
via remote connector
via LAN connector within a network
via RS-232 port

Valve Types
Generally, valves can be operated manually through a lever or electrically
through the valve drive. Valves are available as 2-position valves or multiposition
valves
Ports and channels are described by abbreviations to enable the identification of
a specific valve. Example: 6P/3C = 2-position valve with 6 ports and 3 channels.
In case of the multiposition valves, the input/output port is not counted.
Valves are available in stainless steel or PEEK and with 1/8¨ or 1/16¨ connectors.
2-Position Valves
2-position valves are used for injection, column switching, or column backflush-
ing. In case of the 2-position valves, the rotary motions of the electrical valve are
limited to 2 positions with a rotation angle of 60°.
You control 2-position valves either manually through a lever or electrically
through the valve drive.

Reed Contact
The reed contact inside the 2-position valve causes a short-circuit contact. This
short-circuit contact can be used as a start signal for the entire analytical system
or as a start signal for a measurement with the detector. The function is to be
set on the receiving device.
Multiposition Valves
Multiposition valves are used to switch fluid streams, e.g. the selection of elu-
ents, columns or for fractionating of eluate. Multiposition valves are employed
for fractioning if the form and the size of the fraction containers should be freely
selectable. By combining up to 8 multiposition valves, up to 120 positions can
be used for fractioning in applications in the preparative HPLC.
You control all multiposition valves electrically through a valve drive. 6P-multi-
position valves can alternatively be controlled manually through a lever.

AZURA V 2.1S User Manual, V6860, Version 2.2
Valve Drives
Valve drives are operated by a 24 V direct current motor. The valve drive and
the valve come factory-set. You can change the valve mode by using the DIP
switches (Dual-Inline Package) on the bottom of the device.
By means of chromatography software or a cable for remote control, certain
ports can be controlled directly on a valve.
switch duration of the valve: 150 ms
There is a matching valve drive for every valve type. 6P/3C valves and 6P-multi-
position valves operate on the same valve drive.
Note: Submit any questions about the possible combinations between valves
and valve drives to the Technical Support of KNAUER.
All valve drives come with a ready-mounted valve (see “Repeat Orders” on
page 43).
Seals
You are to use the seals according to their pressure resistance.
For pressures < 50 bar you can use a bicone seal.
For pressures > 50 bar you use Dynaseal for PEEK capillaries and screw fittings
with ferrules for stainless steel or titanium capillaries.

Eluents
Chemical resistance of a valve depends on the stator material and the rotor seal.
Even small quantities of other substances, such as additives, modifiers, or salts
can influence the durability of the materials.
Note: The list of selected solvents was compiled based on research in the perti-
nent literature and is only a recommendation. If there is any doubt, contact the
Technical Support.

Safety Equipment
When working with the device, take measures according to lab regulations and
wear protective clothing:
Safety glasses with side protection
Protective gloves
Lab coat
What must be taken into account?
All safety instructions in the user manual
The environmental, installation, and connection specifications in the user
manual
National and international regulations pertaining to laboratory work
Original spare parts, tools, and solvents made or recommended by KNAUER
Good Laboratory Practice (GLP)
Accident prevention regulations published by the accident insurance compa-
nies for laboratory work
Filtration of substances under analysis
Use of inline filters
Once they have been used, never re-use capillaries in other areas of the HPLC
system.
Only use a given PEEK fitting for one specific port and never re-use it for
other ports. Always install new PEEK fittings on each separate port.
Follow KNAUER or manufacturer's instructions on caring for the columns
More safety-relevant information is listed below:
flammability: Organic solvents are highly flammable. Since capillaries can
detach from their screw fittings and allow solvent to escape, it is prohibited
to have any open flames near the analytical system.
solvent tray: Risk of electrical shock or short circuit if liquids get into the
device's interior. For this reason, place all bottles in a solvent tray.
solvent lines: Install capillaries and tubing in such a way that liquids cannot
get into the interior in case of a leak.
leaks: Regularly check if any system components are leaking.
power cable: Defective power cables are not to be used to connect the
device and the power supply system.

14 Safety
AZURA V 2.1S User Manual, V6860, Version 2.2
self-ignition point: Only use eluents that have a self-ignition point higher
than 150 °C under normal ambient conditions.
power strip: If several devices are connected to one power strip, always con-
sider the maximum power consumption of each device.
power supply: Only connect devices to voltage sources, whose voltage equals
the device's voltage.
toxicity: Organic eluents are toxic above a certain concentration. Ensure that
work areas are always well-ventilated! Wear protective gloves and safety
glasses when working on the device!
