PREFACE

We are grateful for your purchase of Hitachi ZA3000 Series

Polarized Zeeman Atomic Absorption Spectrophotometer.

The ZA3000 series atomic absorption spectrophotometer is an

instrument designed for elemental analysis.

This instrument is intended for use by persons having a

basic knowledge of chemical analysis. Analysis with this

instrument always requires the presence of an analyst

because it involves combustion of a flame or heating of the

atomizing furnace. Remember that improper use of the

analytical instruments, chemicals or samples would result

not only in wrong analytical data but also in consequences

adverse to safety such as personal injury.

SAFETY SUMMARY

General Safety Guidelines

Precautions before Use

Before using the instrument, be sure to read this manual

carefully until you fully understand its contents.

Keep this manual in a safety place nearby so that it can be

referred to whenever needed.

Operate the instrument in the procedure given in this manual.

Be sure to understand and observe the safety instructions

given in this manual.

Be sure to observe the cautions indicated on the instrument

and in the manual. If this is neglected, personal injury or

instrument damage may be caused.

Be sure to follow the original usage of the product and the

usage specified in this manual.

Never attempt modification of the instrument, use of a part

other than specified and instrument operation with safety

devices released, because they are dangerous.

Do not perform operations other than those described in the

instruction manual. If any problem occurs on the instrument,

contact our sales representative or service office.

In analysis with the atomic absorption spectrophotometer,

flame ignition or graphite furnace heating is performed.

Be sure to carry out analysis in the presence of the analyst.

Unattended operation is prohibited.

When using chemicals for analytical operation, be sure to

provide proper ventilation of the laboratory room per local

requirements. Inadequate ventilation could endanger human

health.

SAFETY - 3

SAFETY SUMMARY

General Safety Guidelines (Continued)

Keep in mind that the hazard warnings in this manual and on

the instrument cannot cover every possible case, as it is

impossible to predict and evaluate all circumstances

beforehand. Therefore, just following the given directions

may be inadequate for operation. Be alert and use your

common sense.

Be sure to observe the above precautions strictly.

Otherwise, not only may correct analytical results be

unobtainable, but also personal injury may be caused.

Precautions on Use

In analysis with the atomic absorption spectrophotometer,

flame ignition or atomizer furnace heating is performed.

A fire or explosion may be caused if operation is carried on in

an abnormal condition such as abnormal sound, abnormal

odor, smoke or gas leak.

Be sure to carry out analysis in the presence of the analyst.

Avoid unattended operation.

If an abnormal condition such as abnormal sound, abnormal

odor, smoke or gas leak occurs, immediately turn off the

power supply, close the main valve of the gas cylinder and

take necessary safety measures. After that, contact our

service office.

General Safety Guidelines (Continued)

Precautions on Installation, Maintenance and Relocation

The customer shall not attempt initial installation (upon

delivery) of the instrument.

For safe and exact use of the instrument, service personnel

trained and approved by us will carry out the installation.

Upon completion of installation, check if all the standard

accessories have been supplied.

Lack of a standard accessory or accessories may cause the

instrument to malfunction and compromise the safety.

If anything is missing or damaged or you have any question,

consult with the installer, or our sales representative or service

office.

The contents of maintenance by the customer are restricted to

the items described in this manual. Before maintenance,

read the relevant instructions carefully. Never attempt

maintenance not described in the manual. Failure to do so

could cause malfunction of the instrument or personal injury.

Avoid moving the instrument after installation. This might

result in deviation of the precisely adjusted optical system may

get out of order due to vibration, etc.

If a warning label is deteriorated due to secular change or

damaged, contact our service office.

Replace the life-limited parts of the instrument with new ones

at intervals specified in this manual. Otherwise, a failure

could occur to result in gas leak, water leak, electrical leak or

ignition. For other than the part replacement procedures to

be performed by the user as specified in this manual, refer

replacement servicing to the our sales representative or

service office.

When the instrument reached the end of its useful life, stop

using the instrument. Gas leak, water leak, electrical leak or

ignition may be caused if the instrument is used beyond the

useful life.

SAFETY - 5

SAFETY SUMMARY

Warning Indications in this Manual

Warning indications described in this manual and their locations

in it are listed below.

List of DANGER Indications

Malfunction of Pacemaker!

There is a danger of faulty operation of a pacemaker due to

the strong magnetic field produced.

A person who uses a pacemaker should not come within 1

meter of the instrument, or should avoid handling the

instrument altogether. (Sections 3 and 5 in this manual)

SAFETY - 6

SAFETY SUMMARY

List of WARNING Indications

Beware of High Voltage!

There is a danger of electric shock due to high voltage of

about 400 V. Touching the socket of the hollow cathode

lamp could result in fatal or serious injury.

Before replacing the lamp, be sure to turn OFF the lamp

current (click the lamp OFF button). (Section 1 in this manual)

Beware of Toxic Gas!

Inhalation of toxic gas could be injurious to human health.

Inhaling the vapor emitted from the sample may cause

inflammation of the respiratory tract.

Be sure to operate the ventilating fan to discharge the vapor

emitted from the sample through the exhaust duct.

(Sections 1, 3 and 5 in this manual)

Explosion due to Backfiring!

If water is not supplied to the drain trap, there is a danger of

explosion due to backfiring, or ignition due to gas leakage.

Be sure to supply the drain trap with water.

(Sections 1 and 5 in this manual)

Explosion due to Acetylide Formation!

If samples containing a large amount of copper, silver or

mercury are atomized, it may generate metal acetylide and

cause explosion due to backfiring with louse noise. Do not

measure samples containing a large amount of copper,

silver or mercury.

(Quoted from JIS K 0120 General rules for

atomic absorption spectrometry)

SAFETY - 7

SAFETY SUMMARY

List of WARNING Indications (Continued)

Explosion due to Perchloric Acid!

If metals (copper, silver and mercury) that form metal

acetylide and perchloric acid are contained in a sample

when using a high-temperature burner, they react in the

flame chamber and may result into explosions with loud

noise due to backfiring.

Do not measure samples containing metals that form metal

acetylide and perchloric acid when using a

high-temperature burner.
