and the inlet of the water tank is connected to the outlet of the instrument). After changing the
water tank, pay attention to exhaust the air in the water pump and pipeline, otherwise the water
in the water tank may not circulate due to the air when the water pump is turned on.
11. If the instrument has been running for 2 years, the transmission system needs to be refueled.
First, disconnect the main control panel on the side of the instrument and remove the back panel
of the instrument(the top panel behind the instrument). To find a brush dipped in alcohol to
wash off the greasy or dust on the transmission system. After the alcohol evaporates, use a clean
plastic dropper to drip watch oil or sewing machine oil onto the copper gear of the transmission
system. Finally, connect the power cord of the main control board on the side of the instrument,
and open the ICP-AES working software to observe whether the transmission system rotates. If it
rotates, everything is normal.
12. Frequently scrub the sample room and test bench to remove dust and waste liquid. So as not
to corrode the sample chamber and instruments.
13. After the exhaust is turned on, the vent above the torch in the sample chamber should be
able to gently such a piece of paper, or the operator can feel the suction force. If there is no
suction, it means that the axial fan has a problem and should be replaced ad soon as possible,
otherwise, the smoke and acid mist cannot be discharged, and the instrument will be corroded. If
the grating corrodes, the loss will be large.
14. If the ICP-AES is not running, the power cord of the side main control board must be
disconnected. Otherwise, the heating components of the main control board are prone to aging if
the power is frequently on, and the main control board is likely to burn if it rains and thunders.
5.2 Precautions for Turn On/Off
Before turn on the measurement, you need to make various preparations in advance to avoid
damage to the instrument frequently during a period of time. Because when the instrument is
turned on, the instantaneous strong current impact can easily cause the tube filament to fuse, or
short-circuit between electrodes, and cause premature aging of the tube. Therefore, as far as
possible to minimize the shutdown during use.
Delayed shutdown of cooling system: after the power of the ICP-AES host is turned off, it is
generally necessary to turn off the power of the cooling water tank after a delay of 10 minutes to
ensure that the heat inside the tube is fully dissipated.
Argon pressure: the pressure of argon used in ICP-AES must be controlled at 0.25MPa
—
0.3MPa
and kept stable. To check whether the plasma gas pressure is stable within 5-10 minutes after
each opening. If there is any pressure fluctuation, the operator must immediately turn off the gas
and check the cause, and then turn on the gas again after troubleshooting.
Timely repair:
during the analysis, the operation of the instrument should be observed at any
time. If there is an abnormal situation, the flame must be turned off immediately, and the reason
must be checked or reported to the relevant personnel for handling. The abnormal situation can
be eliminated before proceeding.
Computer dedicated: the computer used by the ICP-AES analyzer must be dedicated, and no one
is allowed to install programs and use the network on it.
Use place: there should be no acid, alkali or other corrosive gas, steam or smoke, so as not to
damage the instrument.
Ground wire maintenance: water the buried wire in dry season to keep the grounding well.
Cooling water quality: the cooling water of the water tank is generally replaced once a year, and
