Chromatography detector

Destructive detectors

• Charged aerosol detector
• Evaporative light scattering detector

• Flame ionization detector
• Flame photometric detector
• Nitrogen Phosphorus Detector
• Atomic-emission detector

• Mass spectrometer

  Non-destructive detectors

• UV detectors, fixed or variable wavelength, which includes diode array detector. The UV absorption of the effluent is continuously measured at single or multiple wavelengths. These are by far most popular detectors for LC.
• Fluorescence detector. Irradiates the effluent with a light of set wavelength and measure the fluorescence of the effluent at a single or multiple wavelength.
• Refractive index detector. Continuously measures the refractive index of the effluent. The lowest sensitivity of all detectors. Often used in size exclusion chromatography for polymer analysis.
• Radio flow detector. Measures radioactivity of the effluent. This detector can be destructive if a scintillation cocktail is continuously added to the effluent.
• Chiral detector continuously measures the optical angle of rotation of the effluent. It is used only when chiral compounds are being analyzed.
• Conductivity monitor. Continuously measures the conductivity of the effluent. Used only when conductive eluents are used.

• Thermal conductivity detector,. Measures the thermal conductivity of the eluent.
• Electron capture detector,. The most sensitive detector known. Allows for the detection of organic molecules containing halogen, nitro groups etc.
• Photoionization detector,. Measures the increase in conductivity achieved by ionizing the effluent gas with UV radiation.
