The present invention relates to control means for controlling a lifter device, the control means having a grip comprising a body extending longitudinally in a first direction in elevation from a first end to a second end, said control means including at least one control member for controlling said lifter device. The ion interface includes an entrance cell with a bore that may be heated for desolvating charged droplets when the ion source is an electrospray source, and a particle discrimination cell with a bore disposed downstream of the bore of the entrance cell and before an aperture leading to the vacuum chamber. By the pick-up module, a sheet article is fed into the transfer channel. This allows for safe disposal of an FDE drive containing confidential data, as the lack of available system specific decryption data makes decryption virtually impossible.
