An apparatus and method for elemental analysis of a formation fluid from a subsurface tool having a housing, a sampling probe for collecting a sample of the formation fluid external to the housing, and a microplasma device within the housing and in fluid communication with the sampling probe. The microplasma device includes an upstream gas system, a sampling valve in fluid communication with the sampling probe and the upstream gas system, an expansion chamber for volatizing the formation fluid sample obtained from the sampling valve, and a microplasma chamber in fluid communication with the expansion chamber for ionizing the volatilized fluid sample. |
