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