Abstract: A method and a system are provided for deriving chemical structures from chemical names. Chemical name fragments are grouped into a number of classifications. The method and the system handle new and old chemical names, including names for organic and inorganic substances. The method and the system handle inverted names, including inverted names with missing commas or with extraneous spaces.

Abstract: An inductively coupled RF plasma generator and method. The plasma generator includes a body having a conduit having a gas inlet and an outlet. Induction structure surrounding the conduit inductively excites the gas, generating a plasma which leaves the conduit outlet as a tail flame. An electrically insulating chimney is positioned at the outlet so that the chimney surrounds the tail flame and no electrical path to ground exists between the outlet and the chimney means. A grounded electrode is positioned downstream of the plasma and sufficiently near the outlet to provide an electrical path to ground from the tail flame shorter than other available paths to ground. The method for generating a plasma utilizing the inductively coupled RF plasma generator involves inductively exciting the gas to generate a plasma which leaves the outlet as a tail flame. The tail flame is surrounded by a chimney so that no path to ground exists between the outlet and the chimney.
