Ruling out false-positive NIAS annotations using triplicate testing and matched oven blanks rather than spectral criteria alone.

Liquid chromatography-tandem mass spectrometry (LC-MS/MS) reveals inflammatory lipid markers in recurrent pregnancy loss.

A multinational research team developed a green, miniaturized CPME-HPLC-DAD method to simultaneously extract and detect four tetracyclines in human urine, offering a simpler, cheaper alternative to LC-MS/MS with improved sensitivity. LCGC International spoke to Fedra Vasileiou, Victoria Samanidou, and Abuzar Kabir, three of the authors of the paper that resulted from this work.
