Sample preparation is one of the most labor-intensive and time-consuming operations in sample analysis. Sample preparation strategies include the exhaustive or non-exhaustive extraction of analytes from matrices. Online coupling of sample preparation with the separation system is regarded as an important goal. In-tube solid-phase microextraction (SPME) is an effective sample preparation technique that uses an open tubular fused-silica capillary column as an extraction device. In-tube SPME is useful for trace enrichment, automated sample cleanup, and rapid online analysis. Moreover, this method can be used to determine the analytes in complex matrices by direct sample injection or merely by simple sample treatment such as filtration. In-tube SPME is frequently combined with high-performance liquid chromatography (HPLC) using online column-switching techniques. Various operating systems and new sorbent materials have been reported to improve extraction efficiency, such as sorption capacity and selectivity. This chapter discusses efficient micro sample preparation techniques for HPLC, especially online automated in-tube SPME.

“…Zhu and co‐workers presented a strategy for synthesis of mesoporous phenolic polymers via the one‐pot template‐free polymerization between resorcinol, formaldehyde and PEI in ethanol and deionized water at 120 °C for 12 h. The as‐synthesized monolith had high a surface area of 548 m 2 g −1 , also demonstrated the ability to enrich glycopeptides from human serum sample. Urea‐formaldehyde polycondensation, as a kind of step‐growth polymerization, was also adopted to synthesize hydrophilic urea‐formaldehyde monolith for the capture of aminoglycosides . More recently, a 1 mm thick chitosan membrane with honeycomb‐like macropores was facilely fabricated by freeze‐casting method applied in glycopeptides enrichment with HILIC .…”

High‐performance liquid chromatography integrated with tandem mass spectrometry (HPLC–MS/MS) has become a powerful technique for proteomics research. Its performance heavily depends on the separation efficiency of HPLC, which in turn depends on the chromatographic material. As the “heart” of the HPLC system, the chromatographic material is required to achieve excellent column efficiency and fast analysis. Monolithic materials, fabricated as continuous supports with interconnected skeletal structure and flow‐through pores, are regarded as an alternative to particle‐packed columns. Such materials are featured with easy preparation, fast mass transfer, high porosity, low back pressure, and miniaturization, and are next‐generation separation materials for high‐throughput proteins and peptides analysis. Herein, the recent progress regarding the fabrication of various monolithic materials is reviewed. Special emphasis is placed on studies of the fabrication of monolithic capillary columns and their applications in separation of biomolecules by capillary liquid chromatography (cLC). The applications of monolithic materials in the digestion, enrichment, and separation of phosphopeptides and glycopeptides from biological samples are also considered. Finally, advances in comprehensive 2D HPLC separations using monolithic columns are also shown.
