Abstract

A method for producing an ion beam having an increased proportion of analyte ions compared to carrier gas ions is disclosed. Specifically, the method has the step of addition of a charge transfer gas to the carrier analyte combination that accepts charge from the carrier gas ions yet minimally accepts charge from the analyte ions thereby selectively neutralizing the carrier gas ions. Also disclosed is the method as employed in various analytical instruments including an inductively coupled plasma mass spectrometer.

Investigations into the origins of polyatomic ions in inductively coupled plasma-mass spectrometry

Thesis/Dissertation McIntyre, Sally M.

An inductively coupled plasma-mass spectrometer (ICP-MS) is an elemental analytical instrument capable of determining nearly all elements in the periodic table at limits of detection in the parts per quadrillion and with a linear analytical range over 8-10 orders of magnitude. Three concentric quartz tubes make up the plasma torch. Argon gas is spiraled through the outer tube and generates the plasma powered by a looped load coil operating at 27.1 or 40.6 MHz. The argon flow of the middle channel is used to keep the plasma above the innermost tube through which solid or aqueous sample is carried inmore »« less

Method for selective detection of explosives in mass spectrometer or ion mobility spectrometer at parts-per-quadrillion level

Patent Ewing, Robert G. ; Atkinson, David A. ; Clowers, Brian H.

A method for selective detection of volatile and non-volatile explosives in a mass spectrometer or ion mobility spectrometer at a parts-per-quadrillion level without preconcentration is disclosed. The method comprises the steps of ionizing a carrier gas with an ionization source to form reactant ions or reactant adduct ions comprising nitrate ions (NO.sub.3.sup.-); selectively reacting the reactant ions or reactant adduct ions with at least one volatile or non-volatile explosive analyte at a carrier gas pressure of at least about 100 Ton in a reaction region disposed between the ionization source and an ion detector, the reaction region having a lengthmore »« less

SST Sample Characterization Analysis of Archive Samples 102-C, 105-C, and 106-C

Technical Report Thomas, D. L. ; Hara, F. T. ; Kaye, J. H ; ...

A major effort at Hanford over the next few years will be to sample and analyze wastes contained in 149 single-shell tanks (SSTs). In preparation for this effort, selected analyses were performed on four archived samples to compare analytical methods and to determine applicability of these methods to the waste samples. The analyses, performed by the Pacific Northwest Laboratory (PNL), used a variety of analytical methods including both PNL technical procedures and adaptations of U.S. Environmental Protection Agency (EPA) technical procedures. Although data are reported for analyses of actual waste tank samples, the data do not serve to characterize anymore »« less
