Ontogenic stages for chemical instrumentation

I am at the stage of life where organ systems draw on some of their redundancies. Repairs to physical insults take much longer now. I am hoping some wisdom has been gained, but one can never be sure. A lot of analytical instrumentation developments have passed in front of me at hundreds of scientific meetings over four decades. A few of these advanced from curiosities to world dominance in our field, others favored less well. For example, I was extremely fortunate to engage with modern LC while it was still incubating in academia and at DuPont and Waters. That was...
