On this episode of Distillations, we tackle Mass Spectrometry – a technology that’s hard to explain and even harder to say. (Go ahead, try it!) First we learn about some of its modern uses – like newborn genetic screening and testing for steroids. Then we dip into the CHF oral history archives to hear a portion of an interview with mass spec pioneer Alfred Nier – who worked on the instrument during the Manhattan Project and beyond. And if you still haven’t gotten your fill of mass spec, visit CHF’s new online exhibit.
