Abstract
The electron capture detector (100) is a device for detecting a sample (α1). The electron capture detector (100) includes a detection cell (1), a sample inlet (2), and an electron emitting element (20). The detection cell (1) forms a reaction chamber (6). The sample inlet (2) introduces a first carrier gas containing the sample (α1) into the reaction chamber (6). The electron emitting element (20) emits electrons (β) into the reaction chamber (6). An ion (α2) derived from the sample component is generated as a result of the electron emitting element (20) emitting electrons (β) into the reaction chamber (6).
Claims12
An electron capture detector for detecting a sample, comprising:
- a detection cell that forms a reaction chamber;
- a sample inlet which introduces a first carrier gas containing the sample into the reaction chamber;
- and
- an electron emitting element that emits electrons into the reaction chamber, wherein
- the electron emitting element includes:
- a surface electrode facing the reaction chamber, and
- a lower electrode facing the surface electrode, wherein
- the electrons are emitted from the surface electrode to the reaction chamber as a result of a voltage being applied between the surface electrode and the lower electrode.
