What You Should Know About SPE?

Solid-phase extraction is the simple method with digital chromatography compounding either binds or flows through. With solid-phase extraction, many samples can be analyzed almost automatically in parallel, but the process may take more time.

Due to its high selectivity, recovery, and reproducibility, SPE methods are widely used for desalting, solvent exchange, sample preservation, and storage.

Compared with liquid-liquid extraction, the advantages of solid-phase extraction are easy to see. It improves throughput in parallel vs. serial processing, as while as decreases organic solvent usage and waste. It achieves higher and more repeatable recoveries, cleaner extracts from contamination, and solvent impurities. The choices of SPE phase and solvent mixtures are always various.

Common applications of solid-phase extraction can be sample cleanup, such as in pharmacokinetic studies, dissolution testing, isolate analytes from complex matrices, such as urine, and plasma. It works perfectly but only removes major interferences, but also eliminates late-elders for the isocratic analysis.

SPE is a reliable method to enrich trace in environmental analysis, the pharmaceutical and agrochemical applications. It is also practiced widely in processes of desalting, solvent exchange, and sample preservation.
