摘要: The extraordinary story of the three-dimensional radiofrequency quadrupole ion trap, accompanied by a seemingly unintelligible theoretical treatment, is told in some detail because quite considerable degree commercial success that technology has achieved. often used conjunction with mass filter, remained laboratory curiosity until 1979 when, at American Society for Mass Spectrometry Conference Seattle, George Stafford, Jr., Finnigan Corp., learned Masters' study Allison Armitage combined trap/quadrupole filter instrument observation electron impact and chemical ionization spectra simple compounds eluting from gas chromatograph. Stafford developed subsequently mass-selective axial instability method obtaining trap alone and, 1983, Corp. announced first as detector In 1987, confinement ions generated externally to was demonstrated soon after, new technique electrospray shown be compatible trap.
