Scientists in Vietnam have performed high-resolution gas chromatography coupled with high-resolution mass spectrometry (HRGC–HRMS) analysis of breast milk to determine the level of dioxin and furan exposure around the Da Nang Agent Orange hotspot in Vietnam. Agent Orange contamination is associated with elevated and persistent levels of dioxins and furans in the environment and are associated with the occurrence of birth defects among other side effects.

Waterpipes have been used to smoke tobacco and other substances for more than four centuries, and are widely believed to be less harmful than cigarettes. In a new study published in the journal Science of the Total Environment, gas chromatography coupled to mass spectrometry (GC–MS–MS) was performed to show that waterpipe smoke can contain potentially harmful microbial compounds.

A team of scientists based in the Czech Republic has developed a micellular electrokinetic chromatography method coupled with tandem mass spectrometry (MEKC–ESI–MS–MS) that uses salts of perfluorocarboylic acid as the volatile background electrolyte (BGE). The method was applied to the determination of 12 drugs from the class of synthetic cathinones in urine samples. According to the paper published in the Journal of Chromatography A, the BGE used to form micelles did not affect the electron ionization efficiency of MS. (1)
