Abstract
An ionization device includes a support configured to support a sample, a probe configured to determine a portion of the sample to be ionized, an irradiation unit configured to emit laser light and is disposed to irradiate with the laser light a liquid bridge portion between the sample and the probe, an extract electrode configured to extract ions obtained by ionizing the sample, a liquid supply unit configured to supply a liquid to a region of the sample, and voltage application units configured to generate an electric field between a portion of the probe that is in contact with the liquid bridge portion and the extract electrode.
Claims16
An ionization device, comprising:
- a support configured to support a sample;
- a probe configured to determine a portion of the sample to be ionized;
- an irradiation unit configured to emit laser light, the irradiation unit being disposed to irradiate with the laser light a liquid bridge portion between the sample and the probe;
- an extract electrode configured to extract ions obtained by ionizing the sample;
- a liquid supply unit configured to supply a liquid to a region of the sample;
- and
- an electric field generation unit configured to generate an electric field between a portion of the probe that is in contact with the liquid bridge portion and the extract electrode.
A method for analyzing a sample, the method comprising:
- forming a liquid bridge portion that links a probe and a sample with a liquid disposed on a surface of the sample;
- irradiating the liquid bridge portion with laser light;
- and
- spraying the liquid on the probe to carry out mass spectrometry on an ionized substance contained in the sample.
