Introduction

Multi-Angle Light Scattering Detector User Manual 7

After-Sales Service

If any problem occurs with this instrument, inspect it immediately and take

appropriate corrective action as described in chapter “Troubleshooting”on page 53.

If the problem persists or symptoms occur that are not described in this document,

disconnect the mains voltage and contact your Agilent representative.

Maintenance

Each component and the entire system should be checked periodically to ensure

that they function normally, otherwise the analysis data may not be precise and

reliable anymore. Typically, a yearly service is recommended.

Agilent offers special maintenance and service contracts to ensure maximum

lifetime and proper operation of the instrument during the entire life cycle. Before

shipment from the factory, this device was thoroughly inspected and tested.

The result of the inspection is documented in the attached protocol. Referring to

this protocol, please check the results of the hardware validation on a regular basis.

Introduction

Multi-Angle Light Scattering Detector User Manual 8

Safety Instructions

The user manual addresses persons who are qualified as chemical laboratory

technicians or have completed a comparable vocational training.

The following knowledge is required:

Fundamental understanding of liquid chromatography.

Familiarity with substances that are used for laboratory experiments.

Awareness regarding the health risks of chemicals.

Participation during a training by Agilent or an authorized person.

If you do not belong to this or a comparable professional group, you may not

perform the work described in this user manual under any circumstances. In this

case, please contact your superior.

The manufacturer does not warrant for any damage or injury resulting from

incorrect operation and maintenance, non-observance of the instructions in this

manual. Prior to delivery, this instrument has been tested for safe usage.

To ensure safe operation of the instrument, please read these safety

instructions carefully before use and follow them always while operating the

instrument.

Observe all of the Warning and Caution sections listed below. They are

extremely important for safety and to maintain a proper working device.

In this manual, Warning / Caution messages are always indicated using the

following conventions:

WARNING

A warning alerts you to situations that could cause physical injury or death.

Do not proceed beyond a warning until you have fully understood and met

the indicated conditions.

CAUTION A caution alerts you to situations that could cause loss of data, or damage of

equipment.

Do not proceed beyond a caution until you have fully understood and met the

indicated conditions.

Introduction

Multi-Angle Light Scattering Detector User Manual 9

Site Requirements

WARNING

•

Pay attention to the weight of the detectors. The detector weighs 16.5 kg

(36.4 lbs). Use proper lifting techniques to avoid potential injuries. Ensure

that you can handle the weight of the load.

•

Consider the entire weight of the combined system including all the

components. The lab table on which this detector is installed should be

sufficiently strong to support the total weight of the whole LC system. It

should be level, stable and have a depth of at least 600 mm. Otherwise, the

instrument could tip over or fall off the table.

•

Take measures to prevent the instrument from falling in the event of an

earthquake or other disaster. Strong vibrations could cause the detector to

fall over, resulting in injury and damage.

•

All other equipment connected to this instrument must be approved to an

appropriate safety standard and have reinforced insulation from the mains.

CAUTION

•

Avoid installation sites that are exposed to corrosive gases, strong vibrations, or

excessive dust. Otherwise, the performance and operability of the detector could

be impaired, and its lifetime may be shortened.

•Never place any liquid on top of the detector.

Bench Space

The module dimensions and weight (see Table “Physical Specifications”on page

23) allow you to place the module on almost any desk or laboratory bench. It needs

an additional 2.5 cm (1.0 inch) of space on either side and approximately 8 cm

(3.1 inches) in the rear for air circulation and electric connections.

If the bench shall carry a complete LC system, make sure that the bench is

designed to bear the weight of all modules.

NOTE The instrument is heavy and thus it is advisable to locate the system on a sturdy

bench.

NOTE Allow additional bench space for a PC if the instrument is to be computer-

controlled.

Introduction

Multi-Angle Light Scattering Detector User Manual 10

Power Considerations

WARNING

•

Ground the instrument.

To prevent electric shock in the event of an accident or electrical discharge,

the detector must be connected to protective earth. This is also important

to ensure stable operation and good data signals.

Ensure that all connected devices are grounded via the mains connector as

well.

•

Do not place heavy objects onto the power cord and keep any hot objects

away. This can damage the cord, resulting in fire, electrical shock, or

malfunction. If the cord is damaged, immediately unplug the mains power

cord and contact your Agilent representative.

•

Never modify the supplied power cord. Do not bend it excessively or pull on

it. Failure to do so could damage the cord, resulting in fire, electrical shock,

or malfunction.

•

Never replace the detachable power cord by an inadequately rated cord.

This can result in fire, electrical shock, or malfunction.

•

The power supply voltages and power consumption of this instrument are

listed in table “Physical Specifications”on page 23. Connect the detector

only to a power supply of the voltage indicated. Otherwise, fire or electric

shock may occur. Ensure that the power supply voltage is stable and has

sufficiently constant current capacity to operate all the components of the

system. If not, the detector will not operate at its rated performance levels.

•

If the power cord or its insulation gets damaged, unplug the cord and

contact your Agilent representative for a replacement cable immediately.

•

Only use mains connection cables admitted for use in your country. We

strongly recommend to only use cables supplied by Agilent.

•

In case of danger, immediately unplug the mains power cord either at the

wall power outlet, the power strip or on the rear of the devices.
