About the use of ICP-AES, maintenance
And turn off the power supply manner. 5 on gas control system maintenance ICP stability of the gas control system normal operation, measured data directly affects the quality instrument, water droplets if there is gas, machinery and miscellaneous debris and other debris can cause flow instability, so of the gas control system to regularly inspect and maintain. First thing to do gas testing, open the gas control system, power switch, the solenoid valve is in working condition. Then open the cylinder and valve. The gas pressure indication in the ratings, and then close the gas cylinder, pressure gauge pointer on the observation of valve should not fall within a few hours or down low. Otherwise, there is gas leakage phenomenon. Needs to be checked and ruled out. Second. As often mixed with argon gas and other impurities in the water, pipes and joints will have some mechanical debris fall off,[link widoczny dla zalogowanych], resulting in gas path is not smooth. Therefore, the need for regular cleaning. Remove some of the pipe section. Then open the cylinder, short period of time to put gas drops in the pipeline. Such as blowing dust. In the installation of gas pipeline. Special dinner experience spectrum is the child containing a transcript of the first H pipe connected to the nebulizer on the road, be careful not to bend the tube too much, otherwise the carrier gas flow rate fluctuation caused instability, affect the determination. 6 on the torch injector system and the maintenance of atomizer is the most sophisticated injection system, the most critical part of the need good maintenance and use. To regular cleaning, especially the determination of high salt and boil possession after the top of the nebulizer, torch nozzle salt will accumulate, resulting in poor air channel plastic stays, often reflected in the determination of strength decline, reflected power equipment level rise. Dust or carbon deposition on the torch lighting will affect the plasma torch and keep indigo, also influence the reflected power, therefore, to regularly use the acid, washed, and finally, washed and dried with anhydrous ethanol,[link widoczny dla zalogowanych], and keep the injection system and the torch clean. 7 in use to minimize the number of stop start to open before the test, you must make arrangements to do the preparatory work in advance, should not open in the same period of time to open the stop, causing damage to the instrument frequently open easily,[link widoczny dla zalogowanych], because each instrument time to open when the instantaneous current is much higher than normal operating current, the instantaneous impact of pulse 2, likely to cause the power tube filament broken wire, touch the very short, and premature aging,[link widoczny dla zalogowanych], so pay particular attention needs to use, once the power to one go,[link widoczny dla zalogowanych], things to do done, do not stop half-way off.
