MOLECULAR DETECTION APPARATUS AND METHOD

摘要

According to one embodiment, a molecular detection apparatus includes an ionizer, a voltage applier, a separator and a detector. The ionizer attaches ions to a substance group including substances that differ in molecular weight to obtain an ionized substance group. The voltage applier applies a voltage to the ionized substance group to cause the ionized substance group to fly toward a detection surface within measurement space. The separator applies a voltage to a flying ionized substance group to bend a flight trajectory, removes a substance whose molecular weight is not more than a threshold from the flying ionized substance group, and extracts a substance whose molecular weight is more than the threshold as a measuring object. The detector performs a photo detection process to obtain a spectrum of the measuring object.

1. A molecular detection apparatus comprising:
an ionizer that attaches ions to a substance group including substances that differ in molecular weight to obtain an ionized substance group; a voltage applier that applies a first voltage to the ionized substance group to cause the ionized substance group to fly toward a detection surface within measurement space; a separator that applies a second voltage to a flying ionized substance group to bend a flight trajectory of the flying ionized substance group, removes a substance whose molecular weight is not more than a threshold value from the flying ionized substance group, and extracts a substance whose molecular weight is more than the threshold value as a measuring object; and a detector that performs a photo detection process to obtain a spectrum of the measuring object attached to the detection surface.
