Best results were obtained in the linear mode with positive-ion detection.
Mass spectra were acquired with an ion source voltage 1 of 25 kV, an ion source voltage 2 of 23.5 kV, a *lens voltage* of 6 kV, by accumulating the ion signals from 1000 laser shots at constant laser fluence with a 100Hz laser.
