The solid-phase extraction (SPE) cleanup step in the QuEChERS method is critical for effectively removing impurities from samples. It can efficiently eliminate impurities such as organic acids, sugars, fatty acids, pigments, chlorophyll, and carotenoids from food samples, thereby enhancing the accuracy and reliability of the subsequent analyses using LC/MS or GC/MS
Pesticides with triazole, triazine, or pyrimidine groups are known to have polar characteristics, making them prone to adsorption on the silanol groups of solid-phase extraction bulk materials, which can result in poor recovery rates. The material used in GL Sciences’ QuEChERS Kit exhibits high inertness, reducing secondary adsorption effects and thereby enhancing the reliability of the analyses of these pesticides.
