Dear Sir
We have ICP-OES Perkin-Elmer model 2000 instrument in our department. Recently, the neon lamp of instrument has problem and does not work. Hence, we buy a new neon source assembly. However, we have these errors with the new buying neon lamp 1- neon lamp do not determine energy 2- neon lamp not function properly. Also, we have some times these errors ( shutter unable to set axial position and spectrometer is time out and problem communicating with one of the devices (Spectrometer). I do not know what is the problem. I change the IEEE-488 GPIB cable and buy the new cable and i change the windows and i install again the winlab 32 ICP software, but we have these problems. I am enthusiastically waiting for your response and thank you in advance.
