Mass spectrometry: what is it and how does it work? Many of us have heard of this practice, but even experts have a hard time explaining what it means. Luckily CHF recently created an online exhibit about mass spec that both demystifies it and reveals its uses in everything from infant genetic testing to the development of the atomic bomb. First we take a look at these everyday applications. Then we reach into our oral history vaults to learn more about the development of mass spec in the words of one of its pioneering scientists.
