Ozone inhalation hazard. Under certain conditions, this instrument
produces ozone concentrations above safe exposure limits. Plumb
waste gases to a fume hood or to the building exterior in accordance
with local, regional and national requirements.
This instrument is rated for an altitude of 2000 m (6562 ft) maximum.
Use of this instrument at an altitude higher than 2000 m can slightly
increase the potential for the insulation to breakdown, which can result in
an electric shock hazard. The manufacturer recommends that users with
concerns contact technical support.
Put the instrument in a position that makes it easy to disconnect the
instrument from the power source.
Put the instrument in a position so that the fan ventilation opening on the
left side is not blocked. Do not allow the power cord to contact hot
surfaces on the QC8500 measurement channels.
There are two placement options:
• Put the instrument on top of the QuikChem System Core (Figure 3).
Make sure that the heater controller is on the left side of the system.
• Put the instrument below the peristaltic pump if the space on top of
the QuikChem system is not available. The peristaltic pump is located
on the left side of the QuikChem system.

Find the correct timing
To find the correct timing in the Omnion FIA:
Items to collect:
• Stop watch or other timer
• Dye (provided with the system) - red dye gives the best results
Note: Due to differences in the viscosity and boiling point of each reagent, do not
use water in place of reagents during the dye test.
1. Put some dye in a test tube.
2. Create a method in Omnion. Enter all valve timing parameters (cycle
period, sample reaches first valve, load period and inject period) and
sampler timing parameters.
3. Run the dye as a sample. Start the timer when the probe goes into
the test tube.
4. Follow the dye through the system. When the sample gets to Port
6 at the injection valve, stop the timer.
5. Record the time, which is the sample reaches first valve time. Make
sure to change this time in the valve timing of the method.
6. Save the method and run the dye again to measure the next
parameter.
7. Run the dye and follow it through the system. When the dye gets to
Port 6, start the timer. This is the instant when the valve toggles for
the first time.
8. When the sample slug gets to Port 6, stop the timer.
9. Record this time and subtract 5 seconds to get the load period that is
specified in the valve timing of the Omnion method.
• The cycle period is specified in the method (cycle period = load
period + inject period).
• The inject period is automatically set by the software once the
cycle period and load period are defined.
Calibrate the instrument
1. Put all reagent lines in their respective reagent bottles.
2. Put the standard solutions into the standard vials.
3. Refer to the analyzer user manual to start a calibration run.
Brackish timing in Omnion FIA
Some of the in-line methods make Brackish (or manual) integration
timing necessary. The QuikChem method shows when the brackish
timing is needed.
To learn more about how to set brackish timing, refer to the software
manual or search for the keywords graphical events programming or
brackish events in the Omnion help system.
Tips
• Do not use the stand-by speed of the peristaltic pump.
• Put reagent lines in deionized water to avoid wasting reagents.
English
11
• Make sure that the deionized water flows through the wash reservoir.
• The sample line is usually not a green-green pump tube. Refer to the
QuikChem method for the correct pump tube.
• Set the peristaltic pump to 35.
• Get to the required temperature before a run is started.
• Allow the reagents to flow at normal speed through the entire system
for at least 15 minutes before a run is started.
• Change the bubble trap membrane once a month or when the
precision is poor or air bubbles are a constant problem.
• Look at the method support data in the QuikChem method and
compare the data to the results. Make sure that the peak height and
area are similar for standards of the same concentration.
• If the instrument and other standard FIA channels run simultaneously,
the sample line for the standard channels can be changed from
green-green to orange-orange. Cut the pump tube like any other
sample line pump tube. Use a dye solution to make sure that the
timing is correct. This change uses less sample.

Troubleshooting
C A U T I O N
Burn hazard. Obey safe handling protocols during contact with hot
sample components.
Decrease the temperature on the instrument to 70 ºC (158 ºF) or less
before the pump tubes are examined. The typical amount of time to
decrease the temperature from 140 ºC (284 ºF) to 70 ºC (158 ºF) is
approximately 10 minutes.
General troubleshooting considerations
The in-line manifolds are different than the standard FIA manifolds. The
main differences are:
• Sample line—The sample line used is usually not a green-green pump
tube. Smaller pump tubes are chosen so that the sample (mixed with
a digestion solution) is put on the heater and on the UV lamp for a
longer period of time.
• Pre-valve sample preparation—The sample line from the sampler
does not go directly to Port 6 of the injection valve. The sample line
mixes with a digestion solution, gets heated, gets UV irradiated, then
goes through the diffusion block or bubble tap membrane, and travels
to Port 6 of the injection valve.
Table 3 shows the most common problems encountered:
Table 3 Troubleshooting guide
Problem Solution
Air spikes in the FIAgram Make sure that the timings agree with the
information in Find the correct timing
on page 11.
Do a degass procedure on the reagents.
Replace the membrane in the dialysis block or
replace the bubble trap membrane.
16 English
Table 3 Troubleshooting guide (continued)
Problem Solution
Poor recovery of a QC sample
that consists of complexcyanide
Make sure that the reagents are made fresh.
Make sure that sample flows through all pump
lines.
Make sure that the temperature agrees with
the QuikChem method.
Look at the small hole on the top of the
instrument to see if the UV lamp is turned on. If
not, replace the lamp.
Poor or no recovery of a QC
sample
Examine the pump tubes for flow.
Examine the temperature setting.
Make sure that the reagents are made
correctly.
For the cyanide determination, make sure that
the acid line is put in the digestion solution.
Examine the pump tubes for the acid, the
sample and the acceptor.
Read the QuikChem method notes to learn
more about the expected recoveries.
Table 3 Troubleshooting guide (continued)
Problem Solution
Air flow though the diffusion
block gets very fast, then slows
almost to a stop
Make sure that there are no blockages or
crimps in the reagent and samples tubing.
Make sure that the waste tubing flows freely. If
not, there is excessive back pressure.
Make sure that the instrument waste goes into
a waste container that is applicable for that
solution. Make sure that the tubing is above
the liquid level and that the container is vented
to prevent pressure inside the container. To
prevent cavitation and vapor lock, the waste
container must be at the same level as the
instrument.
Examine the reagent and water bath tubing for
plugs or crimps. Small dirt particles or algae
from a dirty water bath causes flow problems.
Imprecision when running
replicates
Examine the timings in Find the correct timing
on page 11.
Replace the bubble trap membrane.
Make sure that all pump tubes are in good
condition and that there is good liquid flow.
