Abstract
A device for manipulating ions which includes a perforated folder of electrically conducted material, a first electrode fixed to the holder and a second electrode extending parallel to the first electrode and spaced from the first electrode and holder. The second electrode is connected to the holder through a rigid support of electrically insulated material.
Claims14
A device for manipulating ions, said device comprising:
- (a) a holder of electrically conductive material having an aperture, said aperture having a central longitudinal axis;
- (b) a first electrode extending parallel to said longitudinal axis, said first electrode having a first end fixed and integral with said holder and a second end spaced from said first end holder;
- (c) a second electrode extending parallel to said longitudinal axis and spaced from said first electrode and said holder, said second electrode having a first end adjacent the second end of said first electrode, said second electrode having a second end adjacent the first end of said first electrode;
- and
- (d) a rigid support of electrically insulated material having a first end fixed to said holder, said rigid support having a second end fixed to the second end of said second electrode.
