Abstract
A microhollow cathode discharge (MHCD) cavity and microfluidic channel are combined for interrogation of samples. The apparatus includes a dielectric body and layers of conductive material defining a MHCD cavity containing an environment for carrying a gas discharge within the MHCD cavity. The gas discharge generates gas based electromagnetic waves. Electrical connections apply a cathode discharge potential to the layers of conductive material. A microfluidic channel is integrated on the substrate, and a path extends from the MHCD cavity laterally through a portion of the microfluidic channel. A detector, which may be integrated on the common substrate, is positioned to receive electromagnetic waves from the path and electronic circuitry is coupled to the detector for acquiring and processing data.
