Abstract
In accordance with an embodiment, an analytical apparatus includes a member, a voltage source connected to the member and a detecting section. The member has an inserting portion into which a sample holder supporting a sample is insertable and whose shape corresponds to a shape of the sample holder. The detecting section is configured to detect a substance to be emitted from the sample by field evaporation. The shape of the inserting portion in a cross section of a direction perpendicular to an inserting direction of the sample holder is a shape excluding a perfect circle.
