Abstract
A magnetic adjustment mechanism 100 comprising a chamber 10, an element 12 pivotally mounted within the chamber 10 and comprising a magnetic portion 14, and a magnetic actuator 18 arranged outside the chamber 10 to allow magnetic coupling with the magnetic portion 14 of the element 12 such that movement of the magnetic actuator 18 causes an adjustment of the position of the element 12. The adjustment mechanism 100 may be used within a vacuum chamber of a mass spectrometer to control the position of a moveable element from outside the chamber.
Claims16
A magnetic adjustment mechanism, comprising:
- a chamber, the chamber being a vacuum chamber of a mass spectrometer;
- an element comprising a magnetic portion, the element pivotally mounted within the chamber;
- a magnetic actuator arranged outside the chamber to allow magnetic coupling with the magnetic portion of the element, such that movement of the magnetic actuator causes an adjustment of the position of the element.
A magnetic adjustment mechanism, comprising:
- a chamber, the chamber being a vacuum chamber of a mass spectrometer;
- an element comprising a magnetic portion, the element pivotally mounted within the chamber;
- a magnetic actuator arranged outside the chamber to allow magnetic coupling with the magnetic portion of the element, such that movement of the magnetic actuator causes an adjustment of the position of the element, wherein the movement of the magnetic actuator between a first and a second location causes the position of the element to be adjusted between a first position and a second position;
- and
- a magnetic shielding element arranged between the magnetic portion of the element and the magnetic actuator when the magnetic actuator is the first location and/or arranged between the magnetic portion of the element and the magnetic actuator when the magnetic actuator is in the second location.
A magnetic adjustment mechanism, comprising:
- a chamber, the chamber being a vacuum chamber of a mass spectrometer;
- an element comprising a magnetic portion, the element pivotally mounted within the chamber;
- a magnetic actuator arranged outside the chamber to allow magnetic coupling with the magnetic portion of the element, such that movement of the magnetic actuator causes an adjustment of the position of the element;
- and
- a pneumatic piston configured to move the magnetic actuator.
