I was wondering if anyone had a service manual for either the Bruker Aurora M90 or Agilent 820-MS single quadripole ICP-MS's. I know that Analytik-Jena keeps some tight reigns on them these days, and I haven't been able to convince the two field techs I know to forward me any information. I am specifically looking for anyone has experience in changing out the RF/Induction coils in these instruments, as far as hardware goes they're essentially the same instrument. I know that they're double interlaced, which makes putting a replacement back in a bit of a challenge. Even if you don't have the service manuals and you performed this replacement yourself years ago, any additional information, tips and tricks, or pitfalls to watch out for would be greatly appreciated. 

On an tangentially related note, I have been lurking on these forums for about a year/year and a half and the wealth of knowledge that this community possesses has been nothing short of awe inspiring. I have always thoroughly enjoyed reading your posts and they have served to be an invaluable tool for picking up useful, and often obscure information. I just wanted to thank all of you for participating in a community that has helped me on numerous occasions. The hard work is appreciated. Thanks in advance for any information that you can shed on the subject.
