13 - Non Combustible Solids
The comparison of Supel™ QuE Z-Sep/C18, PSA/C18, and PSA QuEChERS sorbents, in terms of color removal and analyte recovery, is described for the cleanup of oranges prior to pesticide analysis.
Compared to conventional PSA/C18/GCB cleanup, cannabis extracts cleaned with the Supel QuE Verde mixture showed lower GC/MS background, and better recoveries for many pesticides.
Extraction of Permethrin Pesticides from Spinach Using QuEChERS Methodology with Automated Shaking
Glyphosate and related compounds are measured in oatmeal and infant cereal using ion-exchange polymer-based particles for HPLC and SPE. Low level detection was obtained.
A highly selective and sensitive analytical method was developed for chloramphenicol using a QuEChERS type sample preparation approach and LC-MS/MS detection.
Extraction and Analysis of Neonicotinoid Pesticides from Flower Blossoms Using Supel™ QuE and Ascentis® Express
Potency testing in marijuana-infused edibles is an important problem that analytical labs are facing due to the complexity of the involved matrices. Concentration of active ingredients in these edibles can range from a few parts per million to 3.5 parts per thousand. This application demonstrates the extraction and HPLC-UV analysis of the active compounds.
Determination of PAHs in Paprika Powder Using a Novel SPE Cartridge
Supel QuE Z-Sep+ was successfully demonstrated for cleanup of beef kidney matrix, providing reduced background and less interference in the GC-MS analysis of the target pesticides
