Ensuring the safety and sustainability of our environment and food sources is crucial in today’s world. Industrialization and urbanization have led to increased contaminants in water, soil, and agricultural produce. To address this, advanced analytical techniques like Gas Chromatography-Mass Spectrometry (GC-MS) are necessary. GC-MS enables the identification and quantification of various contaminants in many different samples, offering high sensitivity, selectivity, and accuracy. As samples can pose challenges, such as sample preparation, matrix effects, and the risk of analyte loss during analysis, overcoming these challenges is vital to effectively analyze and mitigate the presence of organic and inorganic pollutants in our environment and food.
This digest hopes to provide scientists with more information on how to optimize GC-MS analyses, allowing you to further your research in this field.
