The sample preparation by solid phase extraction (SPE) was introduced in the 1970's and had good commercial progress with the development of cartridges and disks for extraction. An important step in ...

To obtain efficient pre-concentration with good precision and recovery, a C18 solid-phase extraction system was applied. The method was validated and the parameters involved in the validation were ...

Bo Zhang, associate professor at Xiamen University, China, spoke to LCGC International at HPLC 2025 in Bruges, Belgium, about ...

The limit of quantification for the assay method was 100 µg/L. Isolation of zolmitriptan and its metabolites from urine was carried out using 100mg C 2 Bond Elut solid-phase extraction columns.

An uncontrolled amount of blood was added to the blood reservoir part of the cartridge. The capillary fills and then rotates to sit on top of the SPE column. The blood wicks through the SPE to the ...

C18 column, Florisil column and hydrophilic–lipophilic balance (HLB) are the most commonly used SPE columns. Researchers can also develop specific adsorbents to adsorb target materials to improve ...

Consequently, optimizing the solid-phase extraction (SPE) methodology to enhance the purification and preconcentration of these compounds would facilitate their effective separation and enable ...
