Standard Polysiloxane GC Columns

Standard polysiloxane GC columns are the most widely used stationary phases in gas chromatography, offering unmatched versatility, robustness, and stability. Built on a siloxane backbone with tailored functional group substitutions, these standard GC columns are available in a range of polarities, from non-polar 100% dimethylpolysiloxane to mid-polarity phenyl- or cyanopropyl-modified phases. This versatility makes polysiloxane GC columns ideal for a broad spectrum of applications, including environmental testing, pharmaceutical analysis, and petrochemical studies. 

Our selection of standard polysiloxane GC columns includes bonded, crosslinked, and solvent-rinsable phases for reliable, repeatable performance. With excellent thermal stability, low bleed, and outstanding column-to-column reproducibility, these columns deliver high efficiency separations across routine and complex workflows. From non-polar options such as Agilent DB-1 and Agilent DB-5 to mid-polarity phases like Agilent DB-1701, our standard polysiloxane columns provide reliable chromatography performance for laboratories seeking accuracy, durability, and analytical confidence.
