1. Introduction
1.1. Safety precautions
To use this product safely, observe the following precautions.
Nippon Instruments Corporation will not take any responsibility for accidents
caused by a user's carelessness.
1.1.1.Meanings and descriptions of symbols
In the case of mishandling, a user may be killed or suffer a
serious injury immediately.
In the case of mishandling, a user may be killed or suffer a
serious injury.
In the case of mishandling, a user may suffer an injury or material
damage is expected.
*Using this product involves no risk corresponding to "Danger".
1.1.2.Cautions concerning installation
Observe the installation requirements and power
requirements, or a failure may occur.
Install the instrument on a horizontal working table with
sufficient strength, or a slight injury or a failure caused by a
fall or a drop may result.
1.1.3.Cautions concerning handling
Before using a reagent, procure and administer the safety data
sheet (SDS).
When using a reagent, wear protective equipment and carry out
ventilation sufficiently. Reagents to be used for the instrument
include acute toxic and corrosive substances.
Do not disassemble or modify the instrument without
permission, or a failure may result.
Read this document carefully before using the instrument, or a
failure caused by an operational mistake may result.
Observe the range of the specification, or a failure may result.
Do not operate the instrument with a wet hand.
Cut off the power supply before carrying out maintenance work,
or a failure caused by a short circuit may result.
Dispose of effluent appropriately after using the instrument.
Do not touch any driving unit intentionally. An injury is not likely
to occur because the speed and torque are low, but a failure of
the instrument may result.

1.2. Overview
This system is connected to MA-3000, and performs the reducing vaporization
method automatically. It consists of the pump unit which is mounted on MA-3000
rear side, and the auto sample changer SC-5, and the reagent dispenser RD-5.
Auto sample changer SC-5 is available to set 30 samples.Any sample positions
can be random-accessed. Moreover additional samples can be loaded during the
measurement. It also has the function of bubbler cleaning after measuring.
The reagent dispensing unit RD-5 adds of sulfuric acid and reducing reagent, and
feeds distilled water for washing bubbler.

1.3. Measurement principle
Set unspecified samples pretreated by wet degradation etc. Mercury in pretreated
sample has become bivalent mercury ion (Hg2+). 0-valency mercury (Hg0) comes out
when reducing agent (SnCl2) is added and followed by being bubbled. 0-valency
mercury (Hg0) introduces to cell by clean air, and amount of mercury is calculated by
a cold vapor atomic absorption method.
