MATRIX FILM FORMING DEVICE

摘要

A matrix film forming device including a first electrode plate including a mounting surface on which a sample plate P is mounted; a second electrode plate arranged facing said mounting surface; a nozzle which sprays a liquid containing a matrix substance by an electrospray process into the space between the first electrode plate and the second electrode plate and is arranged such that the first electrode plate and second electrode plate are not present over the central axis of the spray stream; and an electric field forming device which forms, between the first electrode plate and the second electrode plate, an electric field causes liquid drops containing charged matrix substance contained in the spray stream to move toward said mounting surface.

主权项

1. A matrix film forming device for forming a film containing a matrix substance on the surface of a sample plate, comprising:
a) a first electrode plate comprising a mounting surface on which said sample plate is mounted; b) a second electrode plate arranged so as to face said mounting surface; c) a nozzle which sprays a liquid containing a matrix substance by an electrospray process into the space between said first electrode plate and said second electrode plate, and which is arranged such that said first electrode plate and said second electrode plate are not present over the central axis of the spray stream; and d) an electric field forming device which forms an electric field between said first electrode plate and said second electrode plate so as to cause drops of liquid containing said matrix substance, which have been electrically charged and are contained in said spray stream, to move toward said mounting surface.
