Agilent J&W DB-5ms Ultra Inert Column Application Note
This document presents a comparative study on the chromatographic behavior of Agilent J&W DB-5ms Ultra Inert columns versus similar columns from four other manufacturers. The analysis focuses on the inertness required for analyzing very active samples, specifically basic compounds that are prone to tailing due to acidic sites in non-inert columns.
The study utilized an Agilent 6890N GC system to test a mixture of six basic compounds, chlorophenols, organophosphorus pesticides, and aromatic positional isomers. Results demonstrated that the DB-5ms Ultra Inert column provided superior peak shapes with significantly reduced tailing factors compared to the competitor columns, ensuring more accurate and reliable analytical results.
