LC-PAH polycyclic aromatic hydrocarbon HPLC liquid chromatography column

SUPELCOSIL ™ LC-PAH polycyclic aromatic hydrocarbon HPLC liquid chromatography column

Product Description: How to Translate

General description

The SUPERCOSIL LC-PAH chromatographic column is specifically designed for the analysis of the important pollutant PAH (polycyclic aromatic hydrocarbons) listed in Method 610 of the United States. 2.1mm and 3.0mm chromatography columns can save solvents and improve sensitivity, especially when the sample size is particularly important. The 3 μ m chromatographic column can provide extremely fast and efficient analysis while maintaining the durability of porous silica gel. They are all economical alternatives to 1.5 μ m pore free silicone gel.

The principle of liquid chromatography columns is the same, and the column length and inner diameter of liquid chromatography also have a significant impact on the separation efficiency

You can see now that the separation efficiency of a liquid chromatography column mainly depends on its chromatographic packing, column length, and column inner diameter. In principle, columns with the same factors have the same separation efficiency

With this in mind, now you can use this more fundamental basis to design your liquid chromatography column, without necessarily relying on expensive standard liquid chromatography columns

Selection of mobile phase flow rate:

A liquid chromatography column is a function of the linear flow rate of the mobile phase in the column, and different column efficiencies can be obtained using different flow rates. For a specific chromatographic column, to achieve ZUIJIA column efficiency, ZUIHAO uses ZUIJIA flow rate. For a chromatographic column with an inner diameter of 4.6mm, a flow rate of 1ml/min is generally selected, while for a column with an inner diameter of 4.0mm, a flow rate of 0.8ml/min is optimal.
