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.

“…This technique is considered as an efficient miniaturization of SPE once it requires smaller amounts of sample, elution solvent, and sorbent material, being applied to a wide variety of analytes and matrices. Positive experiences of their application are described in the literature due to the capacity of miniaturizing of these techniques together with the use of selective materials that presents high sorption efficiency and consequently the reduction of environmental impacts that are caused by conventional extraction techniques .…”

“…It is an efficient sample preparation technique that generally uses a fused silica capillary, PEEK (poly (ether ether ketone)) or steel tube internally coated with a stationary phase. This technique was developed with the purpose of overcoming the disadvantages of conventional SPME, such as low sorption capacity and high brittleness, having as an advantage the direct extraction of the analytes of interest and the concentration of them in the stationary phase that coats internally the capillary . As a consequence, in‐tube SPME uses a capillary column directly coupled to HPLC (in‐tube SPME‐LC), thus allowing the automation of the extraction process, a greater precision of the analytical method and a shorter time of analysis .…”

The accelerated rising of the world's population increased the consumption of food, thus demanding more rigors in the control of residue and contaminants in food-based products marketed for human consumption. In view of the complexity of most food matrices, including fruits, vegetables, different types of meat, beverages, among others, a sample preparation step is important to provide more reliable results when combined with HPLC separations. An adequate sample preparation step before the chromatographic analysis is mandatory in obtaining higher precision and accuracy in order to improve the extraction of the target analytes, one of the priorities in analytical chemistry. The recent discovery of new materials such as ionic liquids, graphene-derived materials, molecularly imprinted polymers, restricted access media, magnetic nanoparticles, and carbonaceous nanomaterials, provided high sensitivity and selectivity results in an extensive variety of applications. These materials, as well as their several possible combinations, have been demonstrated to be highly appropriate for the extraction of different analytes in complex samples such as food products. The main characteristics and application of these new materials in food analysis will be presented and discussed in this paper. Another topic discussed in this review covers the main advantages and limitations of sample preparation microtechniques, as well as their off-line and on-line combination with HPLC for food analysis.

“…The analyte is specifically captured by the extraction phase and then eluted in certain eluent solution for analysis. This innovative approach has been widely used in the analysis of biological, food, and environmental samples . In‐tube solid‐phase microextraction (IT–SPME), a SPME method reported by Pawliszyn and Eisert in 1997, typically uses a fused‐silica capillary to pretreat targeted analytes .…”

In this study, an in‐tube solid‐phase microextraction column packed with mesoporous TiO2 nanoparticles, coupled with MALDI–TOF–MS, was applied to the selective enrichment and detection of phosphopeptides in complex biological samples. The mesoporous TiO2 nanoparticles with high specific surface areas, prepared by a sol–gel and solvothermal method, were injected into the capillary using a slurry packing method with in situ polymerized monolithic segments as frits. Compared with the traditional solid‐phase extraction method, the TiO2‐packed column with an effective length of 1 cm exhibited excellent selectivity (α‐casein/β‐casein/BSA molar ratio of 1:1:100) and sensitivity (10 fmol of a β‐casein enzymatic hydrolysis sample) for the enrichment of phosphopeptides. These performance characteristics make this system suitable for the detection of phosphorylated peptides in practical biosamples, such as nonfat milk.
