|Validation of HPLC analytical method for determination of biogenic amines in agricultural products|
Hyeock Yoon, Jae-Hyung Mah
An analytical method was validated for the quantitative determination of biogenic amines (BA) in agricultural products. The validation results fulfill AOAC criteria and recommendations. This method has been applying to analyze BA in agricultural products for a total dietary survey in Korea.

Adam Vavrouš (1), Lukáš Vápenka (2), Kristina Kejlová (1), Jitka Sosnovcová (1), Dagmar Jírová (1)
We developed a method for simultaneous determination of polycyclic aromatic hydrocarbons, polyfluorinated compounds, ink photoinitiators, phthalates and bisphenols in paper food packaging employing GC–MS/MS and HPLC–MS/MS.
|METHOD DEVELOPMENT FOR THE SIMULTANEOUS DETERMINATION OF METHYLMERCURY AND INORGANIC MERCURY IN SEAFOOD|
Sergio Carneado, Ariane V. Zmozinski, Carmen Ibáñez-Palomino, Àngels Sahuquillo, José Fermín López-Sánchez, Márcia M. da Silva
This work reports the method development for the simultaneous determination of methylmercury (MeHg+) and inorganic mercury (iHg) species in seafood. The study focused on the extraction and quantification of MeHg+ by liquid chromatography coupled to on-line UV irradiation and cold vapour atomic fluorescence spectroscopy (LC-UV-HG-AFS), using HCl 4 mol L-1 as extractant agent.
|A Workflow for Comprehensive Analysis of Forensic Samples Using Electron and Chemical Ionization High Resolution Time-of-Flight Mass Spectrometry|
David E. Alonso, Joe Binkley, and John Rorabeck
EI/CI workflow facilitates confident compound identification. Proper sample preparation is critical for the analysis of complex samples. GC-HRT provides high quality, accurate mass data for:
-Spectral similarity searches (NIST, Wiley, etc.)
-Formula determination (fragment, molecular, and adduct ions)
|Analysis of Low Levels of Bisphenol A (BPA) in Canned Broths|
Ken G. Espenschied, Michael Ye, Olga I. Shimelis, and Christine Dumas
Bisphenol A (BPA) is a primary monomer used in the manufacture of many plastics and epoxies. Some of these plastics are used as beverage containers and as liners and sealants for metal food containers. Because of BPA’s potential to act as an endocrine disrupter at low concentrations in humans, regulations have been enacted regarding BPA concentrations in food and beverages sold for human consumption.
|Fast and Efficient Analysis of Polynuclear Aromatic Hydrocarbons in Edible Oils Using Dual-Layer SPE|
Christine Dumas and Katherine Stenerson
A new dual-layer cartridge for the efficient extraction of PAHs from edible oils
|Total Phenolics and Beta-1,3-Glucans Extracted from Medicinal Mushrooms (Ganoderma lucidum, Inonotus obliquus, and Phellinus linteus)|
Jaecheol Kim, Kiuk Lee, Keum Taek Hwang(1), Gichun Yoo(2)
This study was to analyze the total phenolics, beta-glucans, and beta-1,3-glucans in water extracts of three medicinal mushrooms (Ganoderma lucidum(GL), Inonotus obliquus(IO), and Phellinus linteus(PL)) under different extraction conditions.
|Microextraction techniques combined with X-ray fluorescence spectrometry for determination of different metal ions in water|
Karina Kocot (a), Beata Zawisza (a), Eva Marguí (b), Ignasi Queralt (c), Rafal Sitko (a)
In present work new preconcentration procedures combining microextraction techniques and X-ray fluorescence spectroscopy were developed. Proposed methodologies are promising tools for multielemental analysis enabling detection of natural pollutants in different water samples.
