Background technology
Liquid chromatogram is a kind of separation and analytical technology, its main feature is that using liquid as mobile phase, stationary phase can have more
Kind form, such as paper, thin plate and packed bed.Is in order to distinguish various methods during chromatographic technique develops, according to stationary phase
Form produce respective name, such as paper chromatography, thin-layer chromatography and column liquid chromatographic.The mobile phase of classical liquid chromatogram be according to
By gravity slowly through chromatographic column, therefore the granularity of stationary phase is it is not possible that too small (100 μm~150 μm or so).After separation
Sample is analyzed again after being graded collection so that and not only low separation efficiency, analyze speed are slow for classical liquid chromatogram, but also
Operation is also more complicated.Until the 1960s develop granularity and be less than 10 μm of high-effective fixed phase, and used high pressure defeated
Liquid pump and self registering detector, develop into high performance liquid chromatography, also referred to as high pressure at the shortcomings that overcoming classical liquid chromatogram
Liquid chromatogram.The stationary phase of adsorption charomatography is adsorbent, and the separation process of chromatography is carried out in adsorbent surface, is not entered
The inside of stationary phase.Different from gas-chromatography, also with adsorbent surface suction-operated occurs for mobile phase (i.e. solvent) molecule.It is inhaling
Attached dose of surface, sample molecule and mobile phase molecule carry out absorption competition, thus the selection of mobile phase have to separating effect it is prodigious
It influences, Gradient Elution Method generally can be used to improve chromatographic isolation efficiency.In the analysis of polymer, adsorption chromatography is generally used to
Separate addn, such as azo dyes, antioxidant, surfactant, it can also be used to the composition analysis of petroleum hydrocarbon.By
Adsorption chromatography detection generally has corrosivity, therefore also needs to improve in structure.
