Abstract: At least one of sulfur dioxide and a gaseous hydrosulfide is contacted with at least one of a sulfur-containing salt and a gaseous basic nitrogen compound to produce a solid, sulfur-containing composition.

Abstract: A nitrogen base is separated from the sulfur-containing product of a gas phase reaction between a basic nitrogen compound and at least one of a hydrosulfide and sulfur dioxide by washing the product of the reaction, followed by basification and stripping of the wash liquid. In another embodiment, the nitrogen base is displaced from the sulfur-containing product with anhydrous ammonia.

Abstract: A desulfurization process wherein a sulfur-containing hydrocarbon material is contacted with a sulfur oxide compound and an amine, a salt of an amine, or mixtures thereof. The contacting converts the sulfur component of the hydrocarbon material to water soluble form thereby allowing the sulfur components to be readily separated by water washing.

Abstract: Method and apparatus for interfacing a liquid chromatograph column and a mass spectrometer. The ions necessary for analysis by a mass spectrometer are provided by utilizing a conduit held at a high voltage potential to ionize at least a portion of the solute flowing out of the liquid chromatograph column. Chambers held at low pressure are utilized to evaporate substantially all of the un-ionized solvent present with the solute to provide an ion stream consisting essentially of ionized solvent and solute to the mass spectrometer. The mass of the ionized solute is then determined by the mass spectrometer, thus providing an analysis of the components eluted from the liquid chromatograph column.
