It was assumed that ions leaving the sample source at angles of greater than six degrees did not reach the extraction region. A calculation was also performed using the space focusing methods of Wiley and McLaren. These results were used for comparison. The results obtained are shown in Table 2 below. An illustration from this simulation is shown in Figure 2.
Ions first appear from below and travel to the center of the instrument source.
To clarify the illustration, we have changed the color of the ion trajectory at the time the voltage pulse is applied. In the figure 30 ions are shown, however, in the simulation two thousand ions were flown. The resulting plots are shown in Figure 3. The simulated peak resulting from correlation conditions is substantially narrower than that resulting from Space Focusing conditions. However, they do show a potential improvement to instrument resolution.
