Electrospray ionization interface to high pressure mass spectrometry and related methods

說明書
The term “analyte” refers to a molecule or chemical(s) in a sample undergoing analysis. The analyte can comprise chemicals associated with any industrial products, processes or environments or environmental hazards, toxins such as toxic industrial chemicals or toxic industrial materials, organic compounds, and the like. Moreover, analytes can include biomolecules found in living systems or manufactured such as biopharmaceuticals.
The term “buffer gas” refers to any gas or gas mixture that has neutral atoms such as air, nitrogen, helium, hydrogen, argon, and methane, by way of example.
The term “mass resonance scan time” refers to mass selective ejection of ions from the ion trap with associated integral signal acquisition time.
The term “mass” is often inferred to mean mass-to-charge ratio and its meaning can be determined from context. When this term is used when referring to mass spectra or mass spectral measurements, it is implied to mean mass-to-charge ratio measurements of ions.
The term “microscale” with respect to ion trap mass analyzers refers to miniature sized ion traps with a critical dimension that is in the millimeter to submillimeter range, typically with associated apertures in one or more electrodes of the ion trap having a critical dimension between about 0.001 mm to about 5 mm, and any sub-range thereof. The ion trap electrode central aperture can take on different geometries such as a cylindrical or slit shaped void and arrays of voids are possible.
