CAUTION
Chemical exposure hazard. Obey laboratory safety procedures and wear all of the
personal protective equipment appropriate to the chemicals that are handled. Refer to
the current safety data sheets (MSDS/SDS) for safety protocols.
CAUTION
Chemical exposure hazard. Dispose of chemicals and wastes in accordance with local,
regional and national regulations.
N O T I C E
This instrument is sensitive to electromagnetic and electromechanical interference. These
interferences may have an effect on the analysis performance of this instrument. Do not put this
instrument near equipment that may cause interference.
Install the instrument:
• Indoors in a clean, dry, well-ventilated and temperature-controlled location
• In a location with a flat surface to prevent the unit from movement
• In a location with minimum mechanical vibrations and electronic noise
• In a location with no electromagnetic interferences from equipment such as transmitters, power
switching, etc.

• In a location where there is sufficient clearance to make plumbing and electrical connections
• In a location where the display is easily seen by the user
• In a location with a compatible waste container for the drain tube
4.2 Prepare the reagents and standards
WARNING
Chemical exposure hazard. Obey laboratory safety procedures and wear all of the
personal protective equipment appropriate to the chemicals that are handled. Refer to
the current safety data sheets (MSDS/SDS) for safety protocols.
• Wear protective clothing, safety glasses or face protections and rubber gloves.
• Prepare the reagents in a fume hood.
• Use only glass or PTFE labware.
• Make sure that all of the bottles vent to air after installation.
• Make sure that the applicable accident prevention regulations are observed.
• Dispose of substances correctly and in accordance with the applicable regulations.
For NPOC and IC analysis, a solution of strong acid (e.g., HCl 3 mol/L) is added with a capacity to
transfer 300 ppm of IC from the sample vial (40 mL) into CO2. Use 500 mL of acid solution to prepare
approximately 750 NPOC samples. Adjust the acid concentration or amount of acid added based on
the sample pH or buffering strength to get a sample pH less than 2. Make sure that the sample pH is
less than 2 before the analysis.

analyzer may become hot. Keep chemicals away from hot surfaces.
Make sure to set the analyzer to off. Let the analyzer temperature decrease to room temperature
before a disassembling operation.
English 19

Problem Possible cause Solution
Leakage or loss of
flow
There is a problem in the
furnace injection point.
Add a drop of UPW on top of the furnace
injection point. If there are air bubbles, remove
and fully clean the injection port. As an
alternative, replace the injection port.
There is a problem in IC
injection point. • Add a drop of UPW on top of the IC
injection point. If there are air bubbles, use
a spray bottle to put some UPW into the IC
injection point.
• If the IC injection point continues to push
the UPW out, the condenser has a possible
blockage. Set the condenser temperature to
20 °C (68 °F). Wait 30 minutes. Use the
spray bottle to put some UPW into the IC
injection point. The flow should come back
to the standard value. Contact technical
support.
There is a problem in
particle filter.
The analysis can form CuCl, which is a tiny
powder that can cause a blockage in the filter.
The blockage can increase the pressure,
which can cause the measured flow to be
lower than expected. Use compressed air to
clean the particle filter. Replace the particle
filter.
There is a leak after the
furnace tube is assembled.
The O-ring that seals the bottom of the furnace
tube can expand or shrink during furnace
operation. Remove the complete furnace and
use a flathead screwdriver to tighten the O-
ring.
No air bubbles in
the reagent bottle
UPW
The system startup does
not work.
Make sure that the system starts up correctly.
If the startup is unsuccessful, the oxygen
valves can be damaged. Contact technical
support to replace the oxygen valves.
Area counts too
high
There is a problem in the
needle or needle sleeve. • Examine the needle and the needle sleeve
for damage.
• Make sure that the sleeve starts at 21 mm
from the bottom of the needle. Replace the
needle if necessary.
There is a problem in the
particle filter or a leak in the
system. The pH value of the
acid is incorrect.
• Examine the particle filter. Replace the
particle filter if necessary.
• Make sure that the pH value of the acid is
less than 2.
• Compare the current flow of the instrument
to the flow of the samples in the calibration
line used to calculate the current samples.
The flow has an effect on the area
measured from a sample. A lower flow gives
a higher area count and vice versa.
