Analysis of Early Eluting Pesticides in a C18-Type Column Using a Divert Valve and LC-MS/MS
Description
Many pesticide analyses are based on the QuEChERS extraction method, which uses acetonitrile (ACN) in the final extraction step. This approach can cause peak shape problems (splitting or broadening) especially for the early eluting analytes. The common practice of exchanging the final extraction solvent step for one similar to the mobile phase is laborious and can lead to analyte losses. We demonstrate the ability to override the solvent effects from a sample extract using gradient solvents with HPLC. Additionally, to increase injection volume without overloading the column.| Market: | Environmental |
