Orion 8010cX Ammonia Analyzer
Note:
After replacing the sample injection tube, the filling
volume of the water sample needs to be adjusted according
to the length of the sample injection tube;
Note:
After moving the sensor (including replacing the liquid
storage ring, repairing the rotary valve, etc.), the liquid sensor
needs to be recalibrated;
Cleaning
This instrument supports two cleaning functions:
deionized
water cleaning
and
deep cleaning of cleaning solution
.
Deionized water cleaning function is simply called as the
cleaning in the instrument menu and this Manual. It uses the
deionized water to clean the tubeline system of the entire
instrument, including the reaction cell, measuring cell, buffer
ring, etc. The necessary cleaning function has been
integrated into the analysis process of the instrument, and
what can be used by the user is the function of manual
cleaning. The occasions requiring the manual cleaning
include: multiple manual cleaning operations are required
before the instrument is ready for a long-term shutdown, and
multiple manual cleaning operations are required before the
instrument is recovered for usage after a long-term shutdown.
The deep cleaning function of cleaning solution is simply
called as the deep cleaning in the instrument menu and this
Manual. It uses the special cleaning solution to thoroughly
clean the sample injection tube, buffer ring, reaction cell and
measuring cell, thus eliminating bacteria and removing dirt in
the tubeline system. During a long-term operation of the
instrument, it is recommended that the user shall conduct a
deep cleaning of the instrument tubeline system every week
and replace the cleaning solution once every 6 months.
Liquid Leakage
Maintenance
If there is a fluid leak in the analyzer and it collects in the
bottom of the enclosure an alarm is activated. If the fluid
accumulates the analyzer will stop any measurements for the
purposes of safety. If a fluid leak alarm is activated, proceed
with the following steps:
1.Power off the ammonia nitrogen instrument.
2.Put on protective gloves, goggles and protective clothing.
