Sample pretreatment is essential for the analysis of complicated real samples due to their complex matrices and low analyte concentrations. Among all sample pretreatment methods, solid-phase extraction is arguably the most frequently used one. However, the majority of available solid-phase extraction adsorbents suffer from limited selectivity. Mole...

The human nose has been used as a detector in gas chromatography analysis to evaluate odoriferous compounds related to aroma and quality of wine. Several olfactometric techniques are available to access the description, intensity, and/or duration of the odor of each compound. Olfactometry can be associated with one-dimensional gas chromatography or...

Quickly identification the complex composition of traditional Chinese medicine only through liquid-mass spectrometry technology is difficult. Especially the identification of isomers and co-eluting compounds is even more difficult. In this study, an approach of multidimensional data modes based on an ultra-performance liquid chromatography coupled ...

In a recent study conducted by Zhang et al. (2019), the adenosine monophosphate-specific aptamer has been applied for the rapid extraction of ochratoxin A. Although several publications have already reported the selection of adenosine monophosphate, adenosine triphosphate, and adenosine, there is no report on the detection of ochratoxin A using thi...

β-Cyclodextrin, coupled to graphene oxide supported on aminopropyl silica, was synthesized and characterized. This material was combined with microextraction by packed sorbent to act as the sample preparation step. The analytical method optimization was carried out by employing experimental design and had its figures of merit determined. The result...

Carotenoids consists of a series of conjugated isoprene units that are characteristically highly conjugated through double bonds, leading to the formation of many isomers that are susceptible to oxidation and other chemical modifications. Extreme hydrophobicity and high complexity make carotenoids difficult to identify and quantify. We implemented ...
