I have a 7890 and 5977a which have been sitting for a few years as the result of a failed business venture, I did some successful spme analysis on it a year or so back but just tried some tests from the ALS and it fails. I'm an absolute novice with this machine and need a lesson or two to get me up, running and confident. It's a pity to have this machine just sit and gather dust. I don't mind paying someone for their time in giving me an education on this machine.
Thanks
