Analysis Note	The advent of the die-off of honey bees due to colony collapse disorder (CCD) has spawned investigation into pesticide exposure as the cause. \r\nNeonicotinoids are among the suspected culprits. In this application, the QuEChERS approach using Supel^™ QuE was used for extraction and cleanup prior to analysis of seven neonicotinoid pesticides in flower blossoms. \r\nAscentis^® Express C18 was chosen due to the high efficiency associated with its Fused-Core^® particle, and its relatively low backpressure as compared to sub-2 micron UHPLC columns. This allowed the column to be used in a standard pressure HPLC system with a relatively high concentration of aqueous at the start of the mobile phase gradient.
