Yes. There are many, many types of spectroscopy. This ones involves magnets and radio frequencies, and can (potentially) tell you things about a liquid which is placed into a thin/tall glass tube. The principle under which it operates is the same as an MRI scanner, however, rather than making pictures, it makes squiggly lines. It is not a [https://www.youtube.com/watch?v=9Gq3UEAiWio Gas Chromatograph], nor a Mass Spec, as a few have called it... | Yes. There are many, many types of spectroscopy.

Celebrations were had by drinking beer with the machine (beige box partaking as well), and relative quantification of ethanol vs water were undertaken with wobbly, but within an order-of-magnitude results. Further adventures planned... | Celebrations were had by drinking beer with the machine (beige box partaking as well), and relative quantification of ethanol vs water were undertaken with wobbly, but within an order-of-magnitude results.
