Ion Chromatography Alumina-N Solid Phase Extraction(SPE) Column For For Aromatic Amine Pesticides
Alumina-N SPE Columns Profile
The highly active porous alumina, whose surface electrons can interact with aromatic rings to form pi pi interaction, has strong polar retention ability and Lewis acid properties. Compared with unbound silica gel, alumina is more stable in high pH environment and suitable for the extraction of aromatic amines.
After special treatment, alumina has three types: acid (ALA), neutral (AlN) and basic (ALB), which can match different target compounds.
Technology advantage
High activity porous matrix, large adsorption capacity;
It has good retention property for aromatic amine pesticides;
It is more stable than silica bonded phase in high pH solution.
Alumina-N SPE Columns Application
Analysis of amines, phenols and glycosides in biological matrix, such as catechol;
Detection of pesticide, veterinary drug residues and pollutants in vegetables, fruits and meat products, such as Sudan red, malachite green and organophosphorus pesticides;
Detection of synthetic pigments in water;
Analysis of petroleum composition.

Solid phase extraction technology is based on the theory of liquid-solid chromatography. The samples are enriched, separated and purified by selective adsorption and elution. SPE is a physical extraction process including liquid phase and solid phase. In the process of solid phase extraction, the adsorption force of the adsorbent on the target compound is greater than that of the sample. When the sample passes through the SPE cartridge, the target compound is adsorbed on the surface of the solid, and other components pass through the cartridge with the sample. Finally, the target compound is eluted and collected with appropriate solvent, and then chromatographic analysis is carried out. In recent years, as a sample pretreatment technology, solid phase extraction has been more and more widely used in the laboratory.
Operation Steps
The operation is slightly different for different filler retention mechanisms (filler retention of target compounds or retention of impurities).
1. The filler retains the target compound
Solid phase extraction generally has four steps (Fig. 1)
(1) Activation - remove impurities in the cartridge, activate the filler and create a suitable solvent environment.
(2) Loading - dissolve the sample with a certain solvent, move it into the cartridge and keep the components on the cartridge.
(3) Leaching - remove interferences.
(4) Elution - elute the tested substance with a small amount of solvent and collect it.
2. Filler retention impurities
Solid phase extraction generally has three steps (Fig. 2)
(1) Activation - remove impurities in the cartridge, activate the filler and create a suitable solvent environment.
(2) Loading - move the sample into the cartridge. At this time, most of the target compounds will flow out with the sample, and the impurities will be retained on the cartridge. Therefore, this step should start to collect.
(3) Elution - elute the components with a small volume of solvent and collect them, and combine the collected solution.
