Different types of detectors in hplc
WebThey are broadly divided into general-purpose detectors and selective, high-sensitivity detectors. General-purpose detectors can analyze a wide range of compounds, of which the flame ionization detector (FID) is the most common because it can analyze almost all organic compounds. WebDetectors that can detect all compounds, such as a refractive index detector and an evaporative light scattering detector, are described as “universal detectors”. What is HPLC (High-Performance Liquid Chromatography)?

WebApr 8, 2024 · The UV-Visible detector is the most commonly used detector in HPLC. It works by detecting the absorption of ultraviolet and visible light by the analyte. This type of detector is suitable for the analysis of compounds that absorb UV or visible light, such as aromatic compounds, peptides, and nucleotides. Fluorescence Detector. WebElectrochemical detectors are also widely employed in HPLC. These come in two types: amperometric and conductometric detectors. Amperometric detectors are highly sensitive but are only applicable to analyses that can be oxidized or reduced; conductometric detectors are moderately sensitive and are applicable for detecting anions and cations.
