Which Column Will Best Separate My Chiral Compounds?
Predicting separations for chiral compounds on cyclodextrin stationary phases is very challenging. To make it easier, we compiled resolution values on six different Restek columns for the enantiomers of 21 chiral compounds with different functional groups, including terpenes, alcohols, ketones, lactones, esters, and epoxides.
Exploring the Fundamentals of Solid Phase Extraction (SPE)
There are a lot of choices to make when establishing an SPE method, but the foundations laid out in this article will put you on the path to success. Covering both essential strategies and product characteristics, you’ll quickly learn how to use SPE most effectively to avoid matrix-related problems, such as coelution, interferences, and downtime for instrument maintenance.
Featured Video: Why Are There So Many C18 Columns?
From end-capped to aqueous, there are a multitude of C18 phases to choose from. But, a C18 is a C18, right? In this video tip, we explore the world of C18 columns. We’ll identify the parameters you should consider when selecting a phase and discuss the advantages of using one that is well suited to your specific analysis.
Reduce Sample Prep by 1.5 Hours for Pesticides in Food
Revive in-line sample preparation (ILSP) combines automated sample cleanup with concurrent analysis, significantly speeding up LC-MS/MS multiresidue pesticide analysis. In this example, Revive ILSP is 1.5 hours faster than a traditional QuEChERS workflow for 14 spinach samples.
