Flame Photometer Operating Procedures

1, plug in the air compressor power plug, start the air compressor, see the pressure gauge gradually increased. Pull up the air filter minus the adjustment knob, then turn the adjustment knob clockwise or counterclockwise, the pressure can be adjusted to about 0.15MPa. The pipette is inserted into the solution and the solution enters the atomization chamber. Soon the solution flows out of the waste container. This indicates that the instrument is atomizing normally. A container is placed under the waste container and the waste fluid is collected.

2. Plug in the host power cord, turn on the power switch, and then open the switch on the liquefied petroleum gas cylinder, turn the gas valve to the appropriate position and press the ignition key, and then you can see the spark from the observation window, swirl the gas valve to adjust the flame Height, so that the flame shows a blue cone of flame, the instrument into the warm-up. If the instrument does not display Err1 by the fire, increase the opening of the gas valve and re-ignite by pressing the ignition key. In use, due to exhausted gas or other causes of flameout, an audible and visual alarm Err2 will be displayed and the gas solenoid valve will be automatically shut off to prevent the gas from escaping.

3, due to the combustion of the flame, the injection of the sample is a dynamic process. Initially at room temperature, followed by a warming process, when gas and injection volume are determined. The flame tends to heat balance, when the flame is more stable and the excitation energy is constant, so the reading is stable.

4. The warm-up time is 30 minutes longer. It is better to use distilled water for continuous injection because it can simulate the actual injection conditions.

5, when shutting down, first close the liquefied petroleum gas cylinder (clockwise tightening), after the residual liquefied petroleum gas in the pipeline is burned, the flame will be extinguished. Before turning off the machine, empty it with distilled water for about 5 minutes. After shutting down, the instrument's gas valve can be rotated, the next time you just need to open the switch on the liquefied petroleum gas cylinder and press the ignition switch at the same time, the flame state will not be adjusted, and the gas on and off will be controlled by another solenoid valve. When the fire is out of reach, you can increase the amount of gas and adjust it afterwards.
