First Claim
1. A mass analysis instrument comprising:
- a housing encompassing components of the instrument, the housing defining a space having a volume of equal to or less than about 100,000 cm3, the components within the housing comprising;
a sample inlet component configured to one or both couple with at least one sampler external to the housing and/or receive sample directly;
a gas chromatography sample preparation component operatively coupled to the sample inlet component;
an ionization component operatively coupled to the gas chromatography sample preparation component;
an ion trap component operatively coupled to the ionization component, the ion trap component comprising a cylindrical ion trap or a linear ion trap;
an ion detection component operatively coupled to the ion trap component, the ion detection component comprising an electron multiplier having a conversion dynode;
a vacuum chamber housing at least the ionization component, the ion trap component and the ion detection component; and
a processing and control component operatively coupled to one or more of the inlet component, the sample preparation component, the ionization component, the ion trap component and/or the ion detection component.

Abstract
Person-portable mass analysis instrumentation configured to perform multidimensional mass analysis is provided. Mass analysis instrumentation can include a housing encompassing components of the instrumentation with the housing of the instrumentation defining a space having a volume of equal to or less than about 100,000 cm3. Instrument assemblies are also provided that can include a housing coupled to an instrument component isolation assembly, wherein the component isolation assembly is isolated from an environment exterior to the housing. Exemplary instrument assemblies can include at least first and second components configured to provide analysis with a housing of the instrument at least partially encompassing the first and second components and the first component being rigidly affixed to the housing. An isolation assembly can also be provided that is rigidly affixed to the second component with the isolation assembly being isolated from received inputs of the housing.
