A comprehensive high performance liquid chromatography-diode array detection (HPLC-DAD) workflow for the analysis of 14 cannabinoids in hemp bud extracts within 10 minutes using robust Chromolith® monolithic silica HPLC columns with low column back pressure.
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
Pistachios contain approximately 45% fat, which can result in a significant amount of coextracted matrix in the acetonitrile extract generated using the QuEChERS procedure. A zirconia based adsorbent significantly reduces coextracted matrix prior to LC-MS or GC-MS.
