Fast determination of sulfonamides from egg samples using magnetic multiwalled carbon nanotubes as adsorbents followed by liquid chromatography-tandem mass spectrometry.
TLDR
The proposed method was successfully applied in determining SAs in the eggs obtained from laying hens fed with SA standards, and compared to eggs purchased from local markets, and demonstrate that SAs were detectable in the incurred egg samples. Expand
Fast and selective extraction of sulfonamides from honey based on magnetic molecularly imprinted polymer.
TLDR
A fast and selective method was developed for the determination of sulfonamides (SAs) in honey based on magnetic molecularly imprinted polymer based on liquid chromatography-tandem mass spectrometry and was successfully applied to determine SAs including sulfadiazine, sulfamerazine, sulfamethoxydiazines, sulfamonomethoxine, and sulfadimethoxine in different honey samples.

Dynamic microwave-assisted extraction coupled with salting-out liquid-liquid extraction for determination of steroid hormones in fish tissues.
TLDR
This method was successfully applied to analyze seven kinds of fish tissues, and the recoveries of the steroid hormones for the spiked samples were in the range of 75.3 ± 4.9% to 95.4 ± 6.2%. Expand

Determination of Sulfadiazine Residues in Pork by Molecular Imprinted Column Coupling with High Performance Liquid Chromatography
Abstract A method for the quantitative monitoring of sulfadiazine (SD) residues in pork was established by molecular imprinted column coupling with high performance liquid chromatography (HPLC). TheExpand
Immunoaffinity purification using anti-PEG antibody followed by two-dimensional liquid chromatography/tandem mass spectrometry for the quantification of a PEGylated therapeutic peptide in human
TLDR
An immunoaffinity purification method using anti-PEG antibody followed by two-dimensional LC-MS/MS was developed for MK-2662, an investigational peptide containing 38 amino acids with a 40 kDa branched PEG [poly(ethylene glycol] at C-terminus, which supports more specific PEG recognition provided by IAP.

Preparation of magnetic strong cation exchange resin for the extraction of melamine from egg samples followed by liquid chromatography-tandem mass spectrometry.
TLDR
The proposed method was successfully applied to determine MEL in eggs obtained from different local markets and the MEL eluted from the resins was determined by liquid chromatography-tandem mass spectrometry. Expand
Determination of roxithromycin from human plasma samples based on magnetic surface molecularly imprinted polymers followed by liquid chromatography-tandem mass spectromer.
TLDR
A simple and reproducible method for the determination of roxithromycin in human plasma samples is proposed using surface magnetic molecularly imprinted polymers (MMIPs) as sorbent and the experimental results showed that the MMIPs had high affinity and selectivity toward roxithsromycin. Expand
Simultaneous Determination of Six Active Components in Oviductus Ranae via Quantitative Analysis of Multicomponents by Single Marker
TLDR
The proposed QAMS method was proved to be accurate and feasible based on methodological experiments, and provided a simple, efficient, economical, and accurate way to control the quality of Oviductus Ranae. Expand
