Detecting Histamine in Wine Samples Using Micro Solid-Phase Extraction
In a recent study published in Analytical and Bioanalytical Chemistry, Chia-Hsien Feng of Kaohsiung Medical University in Kaohsiung, Taiwan worked with her team to create a new method for assessing food quality and detecting histamine in wine samples (1).

Histamine, one of the chemicals released within the immune system, can function in several ways, but it is mostly known for causing allergic and anaphylactic reactions (2). However, according to the scientists, histamine can help in assessing food quality. To test this theory, they created a dispersive micro solid-phase extraction (D-μSPE) method that combined dispersive liquid–liquid extraction (LLE) and solid-phase extraction (SPE).
Molecularly imprinted polymers (MIPs) were used in the solid phase to extract histamine from the wine samples, while microwave energy helped reduce synthesis time. The microwave energy allowed for an 11.1-fold shorter synthesis time compared to average MIP synthetic methods. Following the experiments, the scientists found that a dispersive solvent can increase adsorption performance of MIPs in wine samples by 97.7%.
To improve the sensitivity of histamine detection in gas chromatography–mass spectrometry (GC–MS), the scientists later employed their microwave-assisted tandem derivatization method to reuse excess derivatization reagents and reduce both energy consumption and reaction time. Calibration curves were made for wine samples spiked with 0–400 nmol histamine using standard addition, which led to notable linearity and a determination coefficient of 0.999. The intra- and inter-batch relative standard deviations were <0.7% for the slope and <5.3% for the intercept. Meanwhile, the limits of quantitation and detection were 0.4 nmol and 0.1 nmol, respectively. The developed method was deemed a successful analysis method, with the AGREEprep tool evaluating the method’s greenness performance, which proved higher than other reported methods.

Analytical Challenges in Measuring Migration from Food Contact Materials
November 2nd 2015Food contact materials contain low molecular weight additives and processing aids which can migrate into foods leading to trace levels of contamination. Food safety is ensured through regulations, comprising compositional controls and migration limits, which present a significant analytical challenge to the food industry to ensure compliance and demonstrate due diligence. Of the various analytical approaches, LC-MS/MS has proved to be an essential tool in monitoring migration of target compounds into foods, and more sophisticated approaches such as LC-high resolution MS (Orbitrap) are being increasingly used for untargeted analysis to monitor non-intentionally added substances. This podcast will provide an overview to this area, illustrated with various applications showing current approaches being employed.
Detangling the Complex Web of GC×GC Method Development to Support New Users
September 12th 2024The introduction of comprehensive two-dimensional gas chromatography (GC×GC) to the sample screening toolbox has substantially increased the ability to comprehensively characterize complex mixtures. However, for many gas chromatography (GC) users, the thought of having to learn to develop methods on a new technology is daunting. Developing a basic GC×GC method for most (nonspecialized) applications can be accomplished in minimal time and effort given parameter suggestions and ranges to target analytes in a sample of interest. In this article, the authors work describe a simple workflow to develop a GC×GC method for a specific sample upon initial use, with the aim of decreasing the time to accomplish functional workflows for new users.
The Reality Behind Column Insertion Distance
September 10th 2024Column insertion distance is critical to good chromatography. What happens if the column is installed too low in the injection port? Is insertion distance more important when performing split injection or splitless injection? Does the position of the column in the injection port impact reproducibility?
