Pesticide residue testing of turmeric and other (dried) spices is challenging due to their complex compositions and high matrix. An efficient SPE clean-up can be achieved by a new Dual-layer cartridge.
A procedure for cleanup of green tea extracts provides low background and allowed for the analysis of more pesticides at lower levels than QuEChERS. Uses less solvents and no toluene.
The odor and pungency of ginger is due to the presence of terpenes, gingerols and shogaols. These compounds contribute to the highly complex matrix of ginger, which subsequently presents a challenge in low level analyses of contaminants. A novel 2-layer SPE cartridge efficiently reduces background for pesticide determination.
