CHCA, HPA, and ATT crystals are common supports for instances of this technique whose analytes are highly susceptible to damage. Analytes are heated in a vacuum in a version of this technique that relies on blackbody infrared radiative dissociation. Performing this technique on aromatic analytes can result in the formation of an unstable tropylium (“tro-PILL-ee-um”) ion. (10[2])Samples for this technique can be prepared via desorption from a matrix made of an aromatic acid such as (10[1])sinapinic acid. Analytes undergo soft ionization by either electrospray ionization or MALDI (“MALL-dee”) in the first step of this technique. (10[1])The kinetic (10[1])energy of analytes in this technique is measured in its “time of flight” variant. (10[1])For 10 points, name this technique that measures an analyte’s mass-to-charge ratio. ■END■
