Abstract
A discharge ionization current detector for ionizing and detecting a sample component where the sample component is ionized by UV light is provided. The detector includes a UV light source, and a microfluidic channel having a first surface including a conducting or semiconducting material and an opposing second surface including a conducting or semiconducting material, one of the first surface and the second surface being a collection electrode and the other of the first surface and the second surface being a bias electrode, the microfluidic channel being configured to receive a sample component. The microfluidic channel is in fluid communication with the UV light source such that, when activated, UV light from the UV light source can enter the microfluidic channel and ionize the sample component, which releases an electron, and the ionized sample component and electron are detected by the collection and bias electrodes.
