  2. High-performance liquid chromatography - Wikipedia

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

    HPLC has many applications in both laboratory and clinical science. It is a common technique used in pharmaceutical development, as it is a dependable way to obtain and ensure product purity. [59] While HPLC can produce extremely high quality (pure) products, it is not always the primary method used in the production of bulk drug materials. [60]

  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 detector - Wikipedia

    en.wikipedia.org/wiki/Chromatography_detector

    A chromatography detector is a device that detects and quantifies separated compounds as they elute from the chromatographic column.These detectors are integral to various chromatographic techniques, such as gas chromatography, [1] liquid chromatography, and high-performance liquid chromatography, [2] and supercritical fluid chromatography [3] among others.

  5. High-performance thin-layer chromatography - Wikipedia

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

    The spot capacity (analogous to peak capacity in HPLC) can be increased by developing the plate with two different solvents, using two-dimensional chromatography. [8] The procedure begins with development of a sample loaded plate with first solvent. After removing it, the plate is rotated 90° and developed with a second solvent.

    Shimadzu Corporation (株式会社 島津製作所, Kabushiki-gaisha Shimadzu Seisakusho) is a Japanese public KK company, manufacturing precision instruments, measuring instruments and medical equipment, based in Kyoto, Japan. It was established in 1875. [6] The American arm of the company, Shimadzu Scientific Instruments, was founded in 1975.

  9. UV detectors - Wikipedia

    en.wikipedia.org/wiki/UV_detectors

    The most common UV-Vis detectors used are variable wavelength detectors (VWD), photo diode array detectors (PDA), and diode array detectors (DAD). [4] Variable wavelength detectors decide in advance which wavelength is needed for the detection. Its absorbance as function of time is collected in a graphic format called a chromatogram. [5]
