SelectCore HLB based on co-polymerization of N-vinylpyrrolidonre (hydrophilic) and divinylbenzene (hydrophobic), is designed for a broad range of compounds from aqueous samples. Due to its unique features such as monodispersed particles, good chemical and mechanical stability and optimized surface chemistry, SelectCore HLB is popularly employed in sample preparation for advanced liquid and gas chromatography.

Main Features

• Optimized pore size distribution and surface functional group density

• Compressed adsorption and elution volume enable less solvent consumption

• Good recovery with a broad range of compounds from aqueous samples

• Good lot-to-lot consistency

High sample dynamic binding capacity

An important factor affecting the extraction efficiency in solid phase extraction procedure is the dynamic adsorption capacity and desorption capacity of the sorbent. Due to the unique monodispersed polymer matrix, SelecCore HLB exhibits high dynamic binding capacity.

Batch-to-batch reproducibility

Based on the unique monodispersed polymer matrix, SelectCore HLB can provide more stable elution time and volume, hence reproducible results.

Fast and stable drop speed

In SPE, the main factors affecting the column SPE drop speed are the particle size and particle size distribution of the sorbent. Because SelectCore HLB uses monodispersed spherical particles with narrower particle size distribution, the absence of fine particles can improve the flow rate and shorten the time for sample preparation.

Good recovery

Due to the use of monodispersed PVP/DVB particles, SelectCore HLB products exhibit good recovery with a broad range of compounds and results are highly reproducible across different product lots.
