Abstract
A microfluidic photoionization detector (PID) may include a substrate and an electrically conductive layer formed on the substrate. The electrically conductive layer may include a microchannel, and a first electrode region and a second electrode region separated from each other by the microchannel, an ohmic contact layer formed on top of the first electrode region and the second electrode region, and a light source formed on the ohmic contact layer for emitting light toward the microchannel.
