Title: Liquid chromatograph mass spectometer
Inventor: TAKAHASHI TOSHIAKI
IPC: G01N27/62
Filed: 1996-10-24
Abstract: PROBLEM TO BE SOLVED: To achieve stable ionization even during measurement for a long period so as to enhance accuracy and reproducibility of data by preventing a needle electrode, a fine pore electrode and a fine from being smeared or clogged in a liquid chromatograph mass, spectrometer for an atmospheric pressure ionizing method. SOLUTION: A sample component flowing from a liquid chromatograph LC3 is heated to be atomized together with a mobile phase solvent by a nebulizer 6. The atomized sample and the mobile phase solvent are further heated in a solvent removing chamber 7. Most of the mobile phase solvent is evaporated, to be discharged outside of the nebulizer. The sample reaches an ionizing chamber 20 together with the remaining solvent. A needle electrode 8, to which a high voltage is applied, is housed inside the ionizing chamber 20. A corona is discharged from the tip of the electrode 8, thereby ionizing the mobile phase solvent. Subsequently, a proton shift reaction is generated between ions of the solvent and molecules of the sample, resulting in ionization of the sample molecules.
