  2. High-performance liquid chromatography - Wikipedia

    en.wikipedia.org/wiki/High-performance_liquid...

    The schematic of an HPLC instrument typically includes solvents' reservoirs, one or more pumps, a solvent-degasser, a sampler, a column, and a detector. The solvents are prepared in advance according to the needs of the separation, they pass through the degasser to remove dissolved gasses, mixed to become the mobile phase, then flow through the ...

  4. Chromatography - Wikipedia

    en.wikipedia.org/wiki/Chromatography

    The mobile phase consists of the sample being separated/analyzed and the solvent that moves the sample through the column. In the case of HPLC the mobile phase consists of a non-polar solvent(s) such as hexane in normal phase or a polar solvent such as methanol in reverse phase chromatography and the sample being separated. The mobile phase ...

  5. Direct electron ionization liquid chromatography–mass ...

    en.wikipedia.org/wiki/Direct_electron_ionization...

    Major advantages of this technical solution are the following: 1) It delivers high-quality, fully library matchable mass spectra of most sub-1 kDa molecules amenable by HPLC, 2) It is a chemical ionization free interface (unless operated intentionally) with accurate reproduction of the expected isotope ion abundances, 3) Response is never ...

  6. Liquid chromatography–mass spectrometry - Wikipedia

    en.wikipedia.org/wiki/Liquid_chromatography...

    In addition to the liquid chromatography and mass spectrometry devices, an LC–MS system contains an interface that efficiently transfers the separated components from the LC column into the MS ion source. [5] [7] The interface is necessary because the LC and MS devices are fundamentally incompatible. While the mobile phase in a LC system is a ...

  7. Atmospheric-pressure chemical ionization - Wikipedia

    en.wikipedia.org/wiki/Atmospheric-pressure...

    Atmospheric pressure chemical ionization chamber cross section. Atmospheric pressure chemical ionization (APCI) is an ionization method used in mass spectrometry which utilizes gas-phase ion-molecule reactions at atmospheric pressure (10 5 Pa), [1] [2] commonly coupled with high-performance liquid chromatography (HPLC). [3]

    Schematic of the thermospray probe and ion source used in EPA Method 8321B which utilized High Performance Liquid Chromatography-Thermospray-Mass Spectrometry (HPLC-TS-MS). [ 9 ] As a direct sampling technique, thermospray is able to gently ionize various types of analytes such that the resulting spectrum shows few fragments of the molecular ...

  9. Capillary electrophoresis - Wikipedia

    en.wikipedia.org/wiki/Capillary_electrophoresis

    The instrumentation needed to perform capillary electrophoresis is relatively simple. A basic schematic of a capillary electrophoresis system is shown in figure 1. The system's main components are a sample vial, source and destination vials, a capillary, electrodes, a high voltage power supply, a detector, and a data output and handling device ...
