A chamber of metastable species in the flowing afterglow region prepares analytes in a form of this technique called direct analysis in real time, or DART. (15[1])The reflectron (15[1])configuration improves the resolution of a form of this technique that infers the desired property by measuring the time an analyte travels. Fast (*) atom bombardment is a soft ionization method used (10[1])in this technique, which unlike hard methods does not tend (10[1])to induce fragmentation. The (10[1])presence of isotopes in this technique can produce M+1 and M+2 peaks. After (10[1]-5[1])ionization, analytes in this technique are separated by magnetic or electric fields. For (-5[1])10 points, name this technique that separates ions based on their namesake quantity’s ratio to charge. ■END■ (10[1])
