Solid phase extraction, as a sample preparation technique, often requires stationary phases stable in the whole pH range. Styrene-divinylbenzene (SDB) copolymer sorbent can improve the quality of sample preparation.
Excellent structural, mechanical and chemical properties, packaging purity and load ability, as well as stability of the SDB sorbent, offer improved sample clean-up and pre-concentration. This SDB polymeric sorbent is a highly efficient and selective SDB sorbent with high throughput performance. It enables high recovery and reproducibility of results, even in the SPE of compounds of different polarities.
