Application of turbulent flow chromatography in the analysis of biological samples
涡流色谱技术在生物样品分析中的应用

The complexity of biological fluids makes the sample preparation necessary in the analytical process. The traditional techniques, such as liquid-liquid extraction and solid-phase extraction, are time-consuming and labor-intensive. Turbulent flow chromatography (TFC), as an on-line direct injection technique, possesses the advantages of reducing sample preparation steps and enabling the effective pre-concentration and clean-up of biological fluids. Therefore, it is a high-throughput and high-selectivity technique for biological sample pretreatment. In this review, the theory, advantages, characteristics and current status of TFC in bioanalysis are introduced and summarized.
