1. A method of using a gas spring to isolate a payload from vibrational forces, the gas spring having a housing and a piston disposed within the housing, the piston having opposing first and second surfaces, the housing having a first chamber adjacent the first piston surface, the method comprising:

  • coupling the payload to the piston;

    applying a net gas pressure force to the piston by respectively exposing the first and second piston surfaces to first and second gas pressures;

    allowing the piston to be displaced relative to the housing in response to a vibration applied to the housing, whereby the net gas pressure force is modified; and

    modifying the mass of a gaseous medium within the first chamber to equalize the net gas pressure force.
