Yerkanat Syrgabej of Al-Farabi Kazakh National University (Kazakhstan) and his co-authors detail combining liquid chromatography-mass spectrometry (LC-MS) and gas chromatography-mass spectrometry (GC-MS) with matrix-assisted laser desorption ionization-mass spectrometry imaging (MALDI-MSI) to quantify and spatially map tissue contaminants.

MOH contaminants in food pose safety risks, making reliable chromatographic detection essential.

The RGB model, which combines red (analytical performance), green (environmental impact), and blue (practicality), is at the heart of the concept of white analytical chemistry (WAC). While this approach has helped broaden the field’s focus and offered a more balanced evaluation system, analytical science continues to move forward, and with it come new priorities that extend beyond what the RGB framework can fully reflect. This final article of this week's series on WAC curated by Adrián Fuente-Ballesteros of the University of Valladolid (Spain) presents new tools intended to fill that gap.
