Abstract

This paper describes a method for preparing the sample handling and inlet system of a mass spectrometer for analysis of a subsequent sample following analysis of a previous sample comprising the flushing of the system interior with supercritical CO{sub 2} and venting the interior. The method eliminates the effect of system ``memory`` on the subsequent analysis, especially following persistent samples such as xenon and krypton.

System for studying a sample of material using a heavy ion induced mass spectrometer source

Patent Fries, D P; Browning, J F

A heavy ion generator is used with a plasma desorption mass spectrometer to provide an appropriate neutron flux in the direction of a fissionable material in order to desorb and ionize large molecules from the material for mass analysis. The heavy ion generator comprises a fissionable material having a high (n,f) reaction cross section. The heavy ion generator also comprises a pulsed neutron generator that is used to bombard the fissionable material with pulses of neutrons, thereby causing heavy ions to be emitted from the fissionable material. These heavy ions impinge on a material, thereby causing ions to desorb offmore »« less
Techniques for controlling distance between a sample and sample probe while such probe liberates analyte from a sample region for analysis with a mass spectrometer

Patent Laskin, Julia; Nguyen, Son N.; Liyu, Andrey V.

A system includes a mass spectrometer and associated sample interfacing equipment. The sample interfacing equipment includes a platform structured to support a sample thereon, a fluid source, a high voltage source, a dispensing probe electrically coupled to the high voltage source and defining a fluid dispensing passage therethrough, a collection probe defining a collection passage therethrough, a sensing arrangement coupled to the dispensing probe, and control logic responsive to the sensing arrangement to control distance between the dispensing probe and the sample. The dispensing probe facilitates formation of one or more ionized sample analytes when dispensing the fluid through themore »« less

Sample introducing apparatus and sample modules for mass spectrometer

Patent Thompson, C V; Wise, M B

An apparatus for introducing gaseous samples from a wide range of environmental matrices into a mass spectrometer for analysis of the samples is described. Several sample preparing modules including a real-time air monitoring module, a soil/liquid purge module, and a thermal desorption module are individually and rapidly attachable to the sample introducing apparatus for supplying gaseous samples to the mass spectrometer. The sample-introducing apparatus uses a capillary column for conveying the gaseous samples into the mass spectrometer and is provided with an open/split interface in communication with the capillary and a sample archiving port through which at least about 90more »« less
