Chapter 4 Operation
4.1 Instrument Operation
Before starting the machine, the cooling water and the argon gas used for testing must be
connected. Otherwise, the HK-8100 power supply cannot be turned on due to the interlock
protection control of the power supply of the instrument due to the water pressure and air
pressure.
4.1.1 Boot Operation DW-TY-9900 ICP-AES Follow the Steps Below
1. Boot: the first open cycle cooling water tank and water pump power switch, (ICP pressure
switch to open, with special attention to behind the water tank connected to the valve is open -
and the water in the same direction as the handle to open)
2. The ICP power supply switch closed.
3. Hop on the ICP power, pressure, etc. about 3 minutes turn off the lights, light fan switch
Open
→ Open the argon gas cylinders, so that the output pressure control in 0.25Mpa →
Open ICP carrier gas (observed whether the injection capillary is right ) as the normal sample
→
the plasma gas open to 600 - 700 L / h carrier gas, then shut down the plasma temporarily →
(fire action can be down) Press high pressure switch to open, press the light → if light fails,
output power should be switched to level 1 so that the carrier gas fire → Open the loading gas →
output power should switched to level 3 → Observation flame and parameters indicative KV,
Ia, Ig (such as too high or too low can adjust the output power according to different samples).
4. Open the ICP software scans
→ click point zero automatically scan (change level of light) to
find zero-light → select the building method → After the analysis of the capillary into the next
measurement method of peak search of the standard peak → active the looking for peak
method.
High standard to decay(the new method used, commonly used methods generally do not need
the daily decay)
→ STD LOW to measure low standard → measured under the standard
measurement STDHIGH with Standard H → Save → with the distilled water to wash the capillary
→ sample flask under measurement measured in analysis of samples... .... The results can be
printed according to the situation (Afterward, wash the Capillary to ensure the next round of
test).
5. Other method if needed, can be done by redo what above mentions, but do not have to
searching for level of light.
6. Shutdown: from right to left adjust the output power to 0
→ off by high-pressure, ICP Ar gas
cylinder off the power switch → 5 minutes shut argon ICP Switch → 10-hours cooling circulating
water tank and water pump power switch.
Note:(1) If peak could not be found, check if Capillary sampling is not working, or if taken the
wrong standard sample
If the capillary plugs
→ Close flame and gently remove the spray chamber, spray gently removed
from the spray chamber → Open the carrier gas on a finger to block exports of cleaning, spray a
few times
(2) Generally, regulated set pressure regulator do not need to adjust. Unless the spray breaks
down, for the sprayer should be replaced with a new spray adjustable. After
installation, searching for Ca peaks with distilled water and suspend the machine
→ peak
