Evaluation of Gas Chromatography Columns with Radially Elongated Pillars as Second-Dimension Columns in Comprehensive Two-Dimensional Gas Chromatography Vrije Universiteit Brussel
The present study investigated the use of a dedicated gas chromatography (GC) column (L = 70 cm, 75 mu m deep, and 6.195 mm wide) with radially elongated pillars (REPs) as the second column in a comprehensive two-dimensional gas chromatography (GC x mu GC) system. Three stationary phases [apolar polydimethylsiloxane (PDMS), medium polar room temperature ionic liquid (RTIL) based on monocationic phosphonium, and polar polyethylene glycol ...
