This blog is a recognition of the fact that I do not have the time or inclination to regularly update my website proper. We have a lot of interesting things going on in the lab, from development of the Isotopx NGX to cutting edge (U-Th)/Ne measurements to pushing the boundaries of the Ar/Ar technique. I resolve to post about those things here.
To begin, here is a quick example of some of the beautiful argon data we are pulling off of the ATONAs. This is a big shot of air, about 6.6e-13 moles, but the argon-38 measurement on the axial Faraday is still pretty incredible. The numbers are in equivalent 10^11 Ω Faraday volts, so multiply by 10 to get picoamps (or 10000 to get femtoamps if you’re used to Thermo software).
