Preparation of restricted‐access material precolumns by grafting δ‐gluconolactone onto a hybrid silica monolithic column for on‐line solid‐phase extraction of tetracycline residues from milk

Abstract: A restricted‐access material–hybrid monolithic column was prepared based on single‐component organosiloxane and dynamic grafting of δ‐gluconolactone for on‐line solid phase extraction of tetracycline antibiotic residues from milk. The hybrid monolithic column was prepared in a stainless‐steel chromatographic column using methyltrimethoxysilane as the single precursor. δ‐Gluconolactone was covalently coupled to aminopropyl derivatized hybrid monolithic column, which formed hydrophilic structures on the surface … Show more

“…These antimicrobial drugs not only pollute the environment, but also transfer to the human body through the medium of food, and cause damage to human health. Therefore, it is very important to sensitively and accurately detect the antimicrobial drug residues in food samples (Nasr et al, 2014;Huang L. F. et al, 2019). The common problems in monitoring the analysis of real samples are the matrix complexity of real samples and the difficulty of antibiotic extraction.…”

“…Silica-based monoliths as a medium of SPME are confirmed to be superior including thermal stability, mechanical strength, uniform structure, controllable morphology, convective mass transfer, and porous structure [2,3]. For specified analyte detection, various functional groups are introduced into silica monoliths to modulate the extraction performances [4][5][6]. For example, octyl-functionalized silica hybrid monoliths are used in SPME procedures in the determination of cannabidiol and tetrahydrocannabinol [7].…”
