|
In summary, the statistical results collected between 5:00 and 12:00 AM on April 2, 2025. For each injection, we calculate the frequency mean value
(f_mean) and the peak height (P) of 194Pb ions for frames with t > 0.14 s, correct each injection’s frequency by subtracting f_mean, and only sum

I examined the spectrum of 194Pb at the 211 harmonic. It was observed that the peak corresponding to 194Pb82+ was mixed with signals
from some unknown ions. Consequently, we switched to the 212 harmonic, where the frequency of 194Pb82 was measured at 410.5385024. |

Currently, we only use 37% of the injections in our data analysis. However, 63% of the injections have a height below 100, and these may include
single ion injections. We need to visually inspect these injections to identify the single ion injections. |
