Autosampler rail system with magnetic coupling for linear motion

Systems and methods are described for preventing the release of metal particles from an autosampler that could otherwise be detected within a sample during sample analysis. In an example implementation, an autosampler systems includes, but is not limited to, a sample probe support structure; a z-axis support; an outer shuttle coupled with an outer surface of the z-axis support; and an inner shuttle linearly moveable within an interior volume of the z-axis support, the inner shuttle magnetically coupled with the outer shuttle to translate linear motion of the inner shuttle to the outer shuttle.
