6 Intended Use

V 2.1S user manual V6860, version 3.2

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.

Front View

The valve drive has a display and a keypad.

Rear View

On the rear of the device there are the power-connection bushing, ground for

grounding the device, connections for external devices, symbols, warning signs

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

8 Intended Use

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.

Intended Use 9

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.

10 Intended Use

V 2.1S user manual V6860, version 3.2

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 42).

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

V 2.1S user manual V6860, version 3.2

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!

Where is use of the device prohibited?

Never use the system in potentially explosive atmospheres without appropriate

protective equipment. For further information, contact the Technical Support of

KNAUER.

Mounting the Valve onto the Valve Drive

All valve drives are delivered with a ready-mounted valve head. For repeat

orders, the electrical valves are delivered with included adapter plate.

Setting the Valve Mode

You set the mode by means of the 4 DIP switches. The DIP

switch is located on the bottom side of the device.

The valve drive for valves with 6 ports can be set for 6P/3C

or 6P-multiposition valves.

Note: The sample loop is not included with the delivery.

Installing the Sample Loop

To install the sample loop, you have to select the right fittings and seals (see

“Seals” on page 10). There are separate descriptions on how to install PEEK or

stainless steel sample loops.

Description for PEEK Sample Loop

You find either shorter and longer or only longer fittings inside the accessories

kit. Please note that you should always use a long fitting for the syringe port. In

conclusion, you install the sample loop with long fittings on both ends or with a

short fitting on one end and a long fitting on the other end.

Prerequisites

The ends of the sample loop were cut straight at a right angle to the capillary

axis.

The Dynaseals are at hand.

Process Figure

1. Switch the valve drive 1 on.

The initialization of the valve drive

causes the markings on the drive

axle to be on top.

2. Push the valve 3 onto the drive

axle 2. The port 1 of the valve has

to point up.

3. Using the wrench, screw the

adapter plate to the valve drive
