Product Information

  • Name : Chromatograph
  • SKU : BLT-60
  • Category : chromatographs

A chromatograph is a high-precision analytical instrument that separates and quantitatively or qualitatively detects multiple components in a mixed sample by leveraging differences in the rates of adsorption, dissolution, and distribution of various substances between a stationary phase and a mobile phase. It is primarily divided into two categories: gas chromatographs and liquid chromatographs, often used in conjunction with auto-samplers, detectors, and data workstations. It can accurately determine the types and concentrations of trace components in a sample and is widely applied in precision physicochemical analysis scenarios such as quality inspection, research and development, and environmental monitoring.

Chromatograph

Working Principle The sample is carried by a carrier gas or mobile solvent into the chromatographic separation column. Due to differences in the interaction strength between various substances in the mixture and the column packing material, their migration speeds vary significantly, allowing them to be separated sequentially. The separated individual components then enter the detector one by one, where they are converted into electrical signals. The device records the signal spectrum and analyzes it using software, ultimately determining the types of substances present in the sample and their corresponding concentrations.
