CHCA, HPA, and ATT crystals are common supports for instances of this technique whose analytes are highly susceptible to damage. Analytes are (-5[1])heated in a vacuum in a version of this technique that relies on blackbody infrared radiative dissociation. Performing this technique on aromatic analytes can (10[1])result in the formation of an unstable tropylium (10[4])(“tro-PILL-ee-um”) ion. (10[5])Samples for this technique can be prepared via desorption from a matrix (10[1])made (10[1])of an aromatic (10[1])acid (10[1])such as (10[1])sinapinic acid. (10[2])Analytes undergo soft ionization by either electrospray (10[1])ionization (10[1])or (10[1])MALDI (10[1])(“MALL-dee”) in (10[1])the first (10[1])step (10[1])of this technique. (10[3])The kinetic (10[1])energy of analytes in this technique (10[1])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. (10[1])■END■ (10[8]0[4])
