Abstract

See full text

The invention relates to a method of forming a vitrified sample on a sample holder for inspection in an electron microscope. It is known to spray a solution on a grid and then immerse the grid in a cryogenic liquid, such as ethane or liquid nitrogen. The invention proposes to spray small droplets of the liquid on a cryogenic surface, such as a grid or a sample holder in vacuum. The liquid forms vitrified sample material when hitting the surface due to the low temperature of the grid or sample holder.
