The example photoionization detector includes an insulation spacer component and a signal collection electrode component disposed on the first surface of the insulation spacer component. In some examples, the signal collection electrode component includes a first electrode layer and a second electrode layer.
Claims17
A photoionization detector comprising:
- an insulation spacer component comprising ultraviolet radiation shielding material, wherein the insulation spacer component comprises a first surface and a second surface;
- and
- a signal collection electrode component disposed on the first surface of the insulation spacer component and comprising a first electrode layer and a second electrode layer, wherein the first electrode layer is disposed between the insulation spacer component and the second electrode layer, wherein a second layer electrode width associated with the second electrode layer is smaller than a first layer electrode width associated with the first electrode layer,
- wherein the first electrode layer defines a plurality of first electrode layer openings, wherein the first layer electrode width corresponds to a width of the first electrode layer between two of the plurality of first electrode layer openings,
- wherein the second electrode layer defines a plurality of second electrode layer openings, wherein the second layer electrode width corresponds to a width of the second electrode layer between two of the plurality of second electrode layer openings, and
- wherein a bias voltage electrode component is disposed on the second surface of the insulation spacer component.
