Development of an Efficient Solid-Phase Microextraction Monolithic Column for the Analysis of Estrogens in Human Urine and Serum Samples
Estrogen plays a crucial role in various stages of human development and is present in the human body at trace level; therefore, an efficient strategy for the quantitative analysis of trace estrogens is required. However, this analysis is complicated by the presence of extremely complex biological matrices. To address this challenge, a novel method based on monolithic column solid-phase microextraction and ultra-high-performance liquid chromatography-tandem mass spectrometry was developed for the sensitivity analysis of six estrogens: β-estradiol, α-estradiol, 17α-ethynylestradiol, estrone, diethylstilbestrol, and hexestrol, in human urine and serum samples. The method exhibits a low limit of detection (8.6–37 ng L−1), with wide linear ranges (0.10–25 μg L−1) for each analyte and remarkable correlation coefficients (R2 = 0.9953–0.9995). The developed method was successfully used to detect estrogens in urine and serum samples. The six analytes were satisfactorily recovered between 76.2 and 107% with relative standard deviations ranging from 2.5 to 8.3% (n = 3). The results demonstrated that the developed method, based on a poly(methacrylic acid/3-acrylamidophenylboronic acid-co-ethylene glycol dimethacrylate) monolithic column, is an effective enrichment approach toward the analysis of trace estrogens in human urine and serum samples.

Separation sciences, in all their various forms such as chromatography, field-flow fractionation, and electrophoresis, provide some of the most powerful techniques in analytical chemistry and are applied within a number of important application areas, including archaeology, biotechnology, clinical, environmental, food, medical, petroleum, pharmaceutical, polymer and biopolymer research. Beyond serving analytical purposes, separation techniques are also used for preparative and process-scale applications. The scope and power of separation sciences is significantly extended by combination with spectroscopic detection methods (e.g., laser-based approaches, nuclear-magnetic resonance, Raman, chemiluminescence) and particularly, mass spectrometry, to create hyphenated techniques. In addition to exciting new developments in chromatography, such as ultra high-pressure systems, multidimensional separations, and high-temperature approaches, there have also been great advances in hybrid methods combining chromatography and electro-based separations, especially on the micro- and nanoscale. Integrated biological procedures (e.g., enzymatic, immunological, receptor-based assays) can also be part of the overall analytical process.
