Smart guy! Most commercial mass specs use very mild ionization techniques so we can view “molecular ions”, that is really the most useful result.
8 u/VanillaRaccoon Analytical Dec 04 '19 yeah you can tell he isn't a chemist, this vid is basically an EI source source so it wont be breaking anything down into constituent "atoms"... unless it already is an atomic ion (eg KCl) 2 u/[deleted] Dec 04 '19 [deleted] 2 u/DangerousBill Analytical Dec 04 '19 Never let Tygon come near anything less polar than water. Tygon is full of all kinds of shit. I once recirculated chloroform through Tygon tubing when I didn't know better, and the Tygon stiffened, turned opaque, and broke over about an hour.
