Abstract:
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 cm a sample inlet component configured to one or both of 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 electron ionization component operatively coupled to the gas chromatography sample preparation component; single ion trap component operatively coupled to the electron ionization component, the ion trap component comprising a cylindrical ion trap or a linear ion trap; an electron multiplier assembly comprising a conversion dynode and configured to dual polarity ion detection operatively coupled to the cylindrical ion trap or linear ion trap component; a vacuum chamber housing at least the electron ionization component, the cylindrical ion trap or linear ion trap component and the electron multiplier assembly; an instrument component isolation assembly extending between the housing and the vacuum chamber; and a processing and control component operatively coupled to one or more of the inlet component, the sample preparation component, the ionization component, the cylindrical ion trap or linear ion trap and/or the electron multiplier assembly.
