Immunoaffinity and Solid Phase Extraction System

ASPE480 Immunoaffinity and Solid Phase Extraction System is a multifunctional sample preparation instrument that can perform both immunoaffinity chromatography and traditional solid phase extraction. It is widely used for extraction and enrichment of biotoxin, pesticide/veterinary residues, organic materials and other trace contaminants in food, feed, grain, dairy products and herbs industries. The whole operation for ASPE480 is fully automated from removing cap of IAC columns, activation, sample loading to elution. There are 4 extraction channels and 48 samples can be prepared continuously. Built-in syringe pumps can ensure an accurate flow rate and good reproducibility. An environment friendly enclosed frame shall guarantee users' health.

Working principle

Immunoaffinity chromatography principle

Based on the specificity and reversible binding reaction of antigens and antibodies, appropriate solvent is chosen to remove interfering substances and elute the target substances, so as to realize the enrichment and purification of the target substance(s).

Solid phase extraction (SPE) principle

SPE column is activated with reagent or buffer solution, sample is adsorbed on the SPE column stationary phase after being loaded into the SPE column. Using appropriate solvent to remove the interfering substances, so as to realize the enrichment and purification of the target substance(s).

Specifications:

◆ Enable 12 solvents input, 8 solvent bottles (1000mL) and 4 solvent bottles (2000mL) can be placed.

◆ Enclosed frame to guarantee users' health by preventing users contacting with chemical reagents in the operation process. The light-proof

design can effffectively avoid the inflfluence of laboratory light on the light-unstable samples.

◆ Built-in 10.1 inch Android tablet with graphical operation interface, real-time running status display. Method can be easily established or

modifified.

◆ Enable parallel processing of 4 samples, and automatic continuously processing of 48 samples,

fully automation for removing cap, activation, sample loading, washing and elution.

◆ Nitrogen can be chosen for column drying and cleaning to meet requirements of difffferent

standard methods.

◆ Using highly sensitive motor and sliding rail, the accuracy of 3D mechanical arm is 0.1mm.

◆Back of the system is equipped with an air-vent, which can be connected to the air-vent of the laboratory, to ensure it is environment friendly.
