  2. High-performance liquid chromatography - Wikipedia

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

    The theory of high performance liquid chromatography-HPLC is, at its core, the same as general chromatography theory. [41] This theory has been used as the basis for system-suitability tests, as can be seen in the USP Pharmacopeia, [ 42 ] which are a set of quantitative criteria, which test the suitability of the HPLC system to the required ...

  3. Charged aerosol detector - Wikipedia

    en.wikipedia.org/wiki/Charged_Aerosol_Detector

    The charged aerosol detector (CAD) is a detector used in conjunction with high-performance liquid chromatography (HPLC) and ultra high-performance liquid chromatography (UHPLC) to measure the amount of chemicals in a sample by creating charged aerosol particles which are detected using an electrometer.

  4. Chromatography - Wikipedia

    en.wikipedia.org/wiki/Chromatography

    Present day liquid chromatography that generally utilizes very small packing particles and a relatively high pressure is referred to as high-performance liquid chromatography. In HPLC the sample is forced by a liquid at high pressure (the mobile phase) through a column that is packed with a stationary phase composed of irregularly or ...

    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]

  6. Reversed-phase chromatography - Wikipedia

    en.wikipedia.org/wiki/Reversed-phase_chromatography

    Reversed-phase liquid chromatography (RP-LC) is a mode of liquid chromatography in which non-polar stationary phase and polar mobile phases are used for the separation of organic compounds. [ 1 ] [ 2 ] [ 3 ] The vast majority of separations and analyses using high-performance liquid chromatography (HPLC) in recent years are done using the ...

  7. Monolithic HPLC column - Wikipedia

    en.wikipedia.org/wiki/Monolithic_HPLC_column

    A monolithic HPLC column, or monolithic column, is a column used in high-performance liquid chromatography (HPLC). The internal structure of the monolithic column is created in such a way that many channels form inside the column. The material inside the column which separates the channels can be porous and functionalized.

  8. Evaporative light scattering detector - Wikipedia

    en.wikipedia.org/wiki/Evaporative_light...

    An evaporative light scattering detector (ELSD) is a destructive chromatography detector, used in conjunction with high-performance liquid chromatography (HPLC), [1] ultra high-performance liquid chromatography (UHPLC), [2] purification liquid chromatography such as flash or preparative chromatography (using a splitter), countercurrent or ...

  9. Two-dimensional chromatography - Wikipedia

    en.wikipedia.org/wiki/Two-dimensional_chromatography

    Modern two-dimensional chromatographic techniques are based on the results of the early developments of paper chromatography and thin-layer chromatography (TLC) which involved liquid mobile phases and solid stationary phases. These techniques would later generate modern gas chromatography (GC) and liquid chromatography (LC) analysis. Different ...
