Abstract
A micro discharge device (MDD) capable of low voltage discharges in a variety of carrier gases for detection and/or ionization includes a sample introduction capillary having a first open end connected to a gas system and a second open end connected to a cylinder comprising a high dielectric constant material. A high voltage electrode can be placed in close proximity to the outer diameter of the cylinder and at a close linear distance to the second open end of the sample introduction capillary. A region can be formed inside the cylinder between the second end of the sample introduction capillary and the high voltage electrode wherein discharge can be located. An optical emission collector can be located through the flow manifold to a receiving location near the high voltage electrode within a region from inside the cylinder between the high voltage electrode and the manifold.
