We have inherited a 6890/5973 GC-MS system running G1701BA B02.00 chemstation software under Windows NT SP 6a. The system comes up OK and performs a successful tune. However, when performing a run, the "override solvent delay" prompt does not appear and regardless of what solvent delay time is input, the EM never turns on. We have tried reinstalling the software to no avail. Any help would be appreciated.
