AA-6800/6650 Instruction
6. High temperature burner
When using a nitrous oxide-acetylene flame, be sure to use the high temperature burner.
7. Standard analytical conditions
The standard analytical conditions may be changed with the surrounding temperature and humidity,
replacement of the atomizer chamber and graphite tube, and sample solution characteristics. Before
starting the measurement, search the optimum analytical conditions for each element while varying the gas
flow rate and burner height in the case of flame method and the temperature program in the case of
furnace method.
8. Internal repair and maintenance
Since the ordinary maintenance can be performed without removing the main unit cover, do not remove
the unit cover. Also, don't exchange the fuses. If the repair which requires to remove the cover is
necessary, ask it for Shimadzu Representative.
9. Gas supply hoses
Use only the rubber hose supplied as a standard accessory with this product to supply gas to the unit.
Whenever using the equipment, check the gas supply rubber hoses for a crack or deterioration caused by
adhesive chemicals. If a crack or deterioration is found, replace it with a new hose.
10. Drain tube
The drain tube connected to the chamber is not durable with petroleums (kerosene, naphtha, gasoline,
etc). When measuring these samples, ask Shimadzu for information. Every time when using the
instrument, check the drain tube and drain tank and confirm there is no liquid leak from the drain tube.
11. When a lightning surge from the power source line is given
When a momentary large voltage change is given to the instrument from the power source during using the
instrument, the communication with PC is disconnected because some function is stopped to protect the
instrument.
In this case, once turn off the power of the main unit then turn on the power again and connect it to the PC
again. Then the preparation for restarting the measurement is ready. If the instrument doesn't work
properly when powered on, contact your Shimadzu representative.
12. Cleaning the instrument
When cleaning your instrument, wipe off the outer cover and other portions with a dry soft cloth. For details
of cleaning method for component parts, refer to the
Chapter 6 "Maintenance".
