Abstract:
1. A micro discharge device, comprising: 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 dielectric material wherein said sample introduction capillary is adapted to serve as a ground electrode; an electrode placed proximate to an outer diameter of said cylinder and at a linear distance to said second open end of said sample introduction capillary in order to form a discharge region inside said cylinder between said second end of said sample introduction capillary and said electrode; and an optical emission collector located through a flow manifold to a receiving location of said electrode within a region from inside said cylinder between said electrode and said manifold; and an alignment sleeve and an alignment ferrule in order to position said cylinder, said optical emission collector and said flow manifold along a center axis.
