We are three retired analytical chemists who have recently put up a small analytical laboratory. We have purchased an old Perkin-Elmer Elan DRCII ICP-MS. When we turn on the instrument a red led (grid faulty) in the electrical board lights up. Is there something wrong with vacuum system / vacuum gauge or what does this "grid faulty" failure mean?
Your advice will be greatly appreciated.
