Estimating the term…
A monitor that can detect at least one trace molecule in a gas sample. The monitor may include a photoionizer that is coupled to an electron-ionization mass spectrometer. The photoionizer may ionize the gas sample at a wavelength(es) which ionizes the trace molecules without creating fragmentation. The inclusion of the electron-ionizer may allow alternate or additional ionization to detect trace molecules not ionized by the photoionizer. The gas sample may be ionized at atmospheric pressure which increases the yield of the ionized trace molecules and the sensitivity of the mass spectrometer.
A monitor that can detect at least one trace molecule in a gas sample, comprising:
A method for modifying an electron-ionization monitor that can detect at least one trace molecule in a gas sample, wherein the electron-ionization monitor includes an anode grid cage, comprising:
A monitor that can detect at least one trace molecule in a gas sample, comprising:
A method for detecting at least one trace molecule in a gas sample, comprising:
A method for detecting a plurality of trace molecules in a gas sample, comprising:
