Abstract (en)

[origin: DE19915088A1] The method involves subjecting a measured ion current signal to a smoothing short-duration integration and forming (7) a characteristic corresponding to the maximum value of integrator within the entire observation period. The integrator (4) window length is shorter than the entire observation period and is moved smoothly over the observation period.
