Earlier this week, Matt and I dug out an old HPLC that has sat in a basement storeroom for at least the last 5 years or so. He’s currently working hard to reawaken the beast, along with the ancient computer to go with it!
Matt plans to use the HPLC as an autosampler, reagent mixer, pump and fluorometer system to measure ammonium concentrations in seawater in continuous flow and discrete sample mode. So not doing any chromatography with it at all, for now at least. #instrumenthacking!
I posted the above pic on Twitter yesterday but remembered just now that I had a photo of the HPLC in action from a cruise I went on as a PhD student. The machine was used by my PhD contemporary Susa Kadner to measure acrylic acid concentrations, including on a cruise I was on to the Arctic Ocean on the RRS James Clark Ross back in 2001. Here’s the evidence. More amazing than the fact that we still have this old HPLC is the fact that the Jasco fluorometer I was using (to the right of that photograph) was ancient back then and is still going now!
