
Replacing the reagent bottle
If only insufficient reagent remains, measurement cannot be performed correctly. In order to
avoid this, periodically check the remaining amount. If necessary, replace the reagent bottle
with a new one.
Note

When you perform maintenance, be sure to stop the measurement, and then turn the
maintenance switch ON.

The reagent deteriorates differently depending on the storage environment before use and the
usage environment. Therefore, the replacement cycle indicated above should only be used as a
guide.

The reagent deteriorates differently depending on the storage temperature. Store the reagent
before use in a cool and dark place (guide: 15

C or less). When you receive a reagent, use it as
soon as possible.

Inspection
Check the remaining amount of each reagent.
If only insufficient reagent remains, replace the reagent bottle with a new one as instructed
below.
Note
If the remaining amount of reagent is less than 1 cm from the bottom of the reagent bottle, it is
necessary to replace the reagent immediately.

Replacement
There are two types of reagent replacement method: collective replacement and individual
replacement.
Note

A new reagent bottle is fully charged with reagent. If you grab the side of the bottle while the cap
is open, the reagent may spill out. When opening the cap of the reagent bottle for setting or
replacing the reagent, be careful not to spill the reagent. For example, place the bottle on a flat
surface.

Take care not to damage the reagent tray (load capacity: 5.0 kg)
While the reagent tray is pulled out, do not place anything other than the reagent bottle specified
by HORIBA Advanced Techno.

When setting or replacing the reagent, match the color of the tube connected to the nozzle unit
with that of the reagent bottle label. Then, set it in the correct location.
If it is set in an incorrect location, measurement cannot be performed correctly.

WARNING
Chemical hazard
Some reagents are poisonous and thus it is extremely dangerous if they are touched by hand. When
replacing the reagent bottle, be sure to wear protective goggles and gloves, and be extremely careful
so that your skin will not come in direct contact with reagents. When replacing the reagent bottle, the
reagent may spill off from the bottle. If it spills off, wipe it off completely.
