SFC can provide solutions for challenging separations beyond traditional normal- and reverse-phase HPLC. But to get the best results, you need to select the right columns. This eBook examines column options for accurately and efficiently separating a variety of pharmaceutical compounds using SFC. Topics include SFC column fundamentals and considerations, selecting SFC columns, and columns for SFC chiral and achiral analysis.

In gas chromatography (GC) analysis, the use of proper high-purity gases is critical to the speed and accuracy of analysis. Laboratories worldwide are taking control of their gas supply with onsite gas generation as a safe and economical way to stabilize gas costs while improving the speed of analysis. LCGC recently sat down with Rod Wilson, Product Manager of Parker Hannifin’s Analytical Gas Business, to discuss the advantages of Parker gas generators.

The Nexera UC UHPLC/SFC switching system combines both UHPLC and SFC analysis modes in a single system, allowing you to easily switch between the two techniques in as few as ten minutes without reconnecting flow lines. So, you get the added resolution of UHPLC and the added selectivity of SFC to quickly develop separations without compromising chromatographic accuracy. Learn about five key benefits.
