The ANALYSETTE 22 can be universally used to determine the parcle

size distribuon of suspensions, emulsions and solids. It is mainly used in

research and development and in quality and process control.

The ANALYSETTE 22 uses the FRITSCH patent with a measuring cell which

can be posioned in the convergent laser beam to determine parcle

size distribuon.

Safety informaon and use

- 8 -

The laser parcle sizer described here is an operaons resource for use in

industrial environments. This operaons resource possesses hazardous

live components and laser radiaon sources during operaon. Therefore

serious health hazards or material damage can result, e.g., aer the

impermissible removal of the required covers or insucient mainte-

nance.

1.3 Obligaons of the operator

Before using the ANALYSETTE 22, this manual is to be carefully read and

understood. The use of the ANALYSETTE 22 requires technical knowl-

edge; only commercial use is permied.

1.6 Device safety informaon

nThe laser parcle sizer has been designed from the viewpoint of

safety to users; nevertheless, residual hazards cannot be ruled out.

nThe device may only be used for the purpose described in

Ä

Chapter

1 ‘Safety informaon and use’ on page 8.

nOnly use original accessories and original spare parts. Failure to

observe this instrucon can compromise the funconing of the

machine.

nSafe conduct must be strictly observed during all work.

Safety informaon and use

- 12 -

DANGER!

Explosion hazard!

– When measuring oxidisable substances, e.g. metal,

organic material, wood, coal, plascs etc. there is a

risk of spontaneous combuson (dust explosion) if

the proporon of ne parcles exceeds a certain

percentage. Therefore special safety measures (e.g.

measurement in suspension) must be taken and

the work must be supervised by a specialist.

– The device is not explosion-protected and is not

suitable for measuring explosive, ammable or oxi-

dising substances.

– The device must not be used in electrically conduc-

ve, dusty or damp environments.

– Do not use highly ammable and ammable liquids

such as alcohols, ketones and benzines etc.

DANGER!

Mains voltage

– Do not allow any liquids to run inside the device.

WARNING!

The maximum accepted concentraon (MAC) levels of

the valid safety regulaons must be observed. If neces-

sary, venlaon must be provided or the machine must

be operated under an extractor hood.

nUnauthorised alteraon of the device will void Fritsch's declaraon

of conformity to European direcves and void the guarantee.

1.6.1 Laser

NanoTec

2 semiconductor lasers

Laser 1: Wavelength 532 nm, power 10 mW

Laser 2: Wavelength 850 nm, power 20 mW

Safety informaon and use

- 13 -

The lasers are classied in Class 3b EN 60825-1/11.2001 and with regard

to the laser emier may only be operated in the valid range of the safety

regulaons of the German Labour Inspectorate in accordance with the

corresponding safety instrucons in EN 60825 Part 1 and 2. The user

must inform himself about the dangers of handling laser beams before

use.

WARNING!

Laser radiaon!

Laser devices of laser class 3B and 4 are dangerous for

the human eye, so that even an exposure me of 0.25

sec is sucient to cause permanent damage to the

rena. Therefore it is mandatory for every person who

is operang the device with the housing open during

repairs or maintenance to wear suitable safety goggles.

The safety goggles must be suitable for the wavelength

of the laser being used.

WARNING!

Laser radiaon!

– Never look directly into the laser beam.

– Always avoid placing any reecve objects in the

laser beam.

– Wear suitable safety goggles during maintenance

and adjustment work on the open laser emier. (<

10 mW, 532 and 940 nm).

It is not necessary to appoint a laser safety ocer for the ANALYSETTE 22

as the laser radiaon sources are fully enclosed and not accessible.

The ANALYSETTE 22 is classied in laser protecon class 1 according to

EN 60825.

The laser is automacally switched o when the meas-

uring cell inseron is removed.

1.6.2 Ultrasound

NOTICE!

– Do not operate the sample bath without liquids.

–Do not reach into the liquid during irradiaon.

Safety informaon and use

- 14 -

The ultrasonic emier installed in the wet dispersion unit has a power of

up to 120 was and a frequency of 40 kHz. It converts electrical energy

into ultrasound waves, which disperse in the liquid and result in so-called

cavitaon. Cavitaon both destructs agglomerates and degasses the

liquid.

During degassing the cavitaon noise changes, loud degassing noises are

eliminated at the end of the degassing procedure and the device appears

to work more quietly. Lower noise levels do not imply reduced ultra-

sound power but rather the end of the degassing procedure.

DANGER!

Explosion hazard, combusble substances

– Do not use highly ammable and ammable liquids

such as alcohols, ketones and benzines etc. or any

chemicals, which contain or could break down into

chloride ions (some disinfectants, household deter-

gents and washing-up liquids), in the dispersion

unit. See

Ä

Chapter 5.1.2 ‘Selecng the liquids’

on page 48.

–Aer prolonged use the liquid warms up, therefore

check the temperature.

– Do not use aggressive liquids (e.g. strong acids,

concentrated salt soluons).

1.7 Protecve equipment

Protecve equipment, such as covers, must be used as intended and may

not be disabled or removed.

1.8 Electrical safety

Connect the measuring unit and supply units to a mains line protected

with a residual current circuit breaker.

The mains switches separate the devices from the mains on two poles.

The mains fuse provides overload protecon.

3.3 Seng up

The supply units of the ANALYSETTE 22 must be placed

directly beside the measuring unit.

Place the device indoors on a at, stable surface. It does not have to be

fastened to the surface.

Please avoid excessive heat build-up (from sunlight, heaters or similar), a

dusty environment and its eect on the interior of the measuring unit as

well as extreme humidity (>85%).

The permissible ambient temperature during operaon of the device is

10°C to 35°C. Storage is possible from 1°C to 40°C. If it is ancipated that

the temperature range e.g. for a scheduled transport is lower than the

permied range, the enre suspension circuit (dispersion unit, hoses and

measuring cell in the measuring unit) must be thoroughly rinsed rst

with pure ethanol and then the ushing liquid must be completely

removed.
