Bronze Disease Advice Needed Please!

Holy Cow!! You're kidding ! I still have their book "Introduction to Modern Liquid Chromatography." It used to be on my desk at work for quick and ready reference and I've kept it with me all these years. And you've met these guys, and took a course from them, that is just so cool. BTW: to show my age my book is the 2nd Edition published in 1979 and I have it in my hands "as we speak." It just took me a second to find it.
Wow, you are really bringing back a lot of memories...This is awesome, I love these guys and have used their book so much the binding is falling apart. The cover page of my book says Snyder is from Tarrytown, NY and Kirkland from Wilmington, DE. What school did they teach at?
Thanks, Wayne

Outstanding....I too took several post graduate courses but never one taught by such distinguished authors. Let's see, positive peaks before t=o, I sort of remember seeing these, small peaks about 1/2 to 1cm in height and just thought they had something to do with a detector disturbance at the point of injection with our automatic sampling system. A lot of my work was with carbamates using a post column derivitization setup where the analytes were hydrolyzed with NaOH, o-phthalaldehyde(OPA), and a real foul smelling substance whose name eludes me right now, but we were looking for ppb levels with fluorescence detection and always seemed to have a little baseline disturbance with our setup. Nothing serious but these peaks you are mentioning do sound somewhat familiar to me. Fortunately all of our work was confirmed by LC/MS and I was always proud of the quality of our reports. We would get quarterly test samples to maintain our certification and always performed at the highest levels. Lot of fun and at times I do miss it...also miss troubleshooting and repairing analytical instruments. Heck, I'd have those instruments completely torn apart, our lab director would walk in, take one look at it and just shake his head and walk out. But I always managed to put everything back together without too many 'extra' pieces laying around. We were a private lab and when a customer wanted something done, he wanted something done, and we didn't have the luxury of waiting for a repair technician to show up---we did most of the repair work ourselves. Sorry for rambling here, just enjoying reminiscing about some very interesting and enjoyable times.
