Agilent J&W Standard GC Columns

Agilent J&W Standard GC Columns represent the benchmark in reliable chromatography performance. These polysiloxane stationary phases offer excellent inertness, thermal stability, and reproducibility across a wide range of applications.

Standard polysiloxane GC columns, including DB-1, DB-5, HP-5, and CP-Sil 8 CB, feature siloxane backbones with distinct functional group substitutions that determine selectivity, polarity, and elution order. Their robust chemistry ensures consistent separation performance for environmental, petrochemical, and pharmaceutical analyses.

Chrom Tech provides a complete selection of genuine Agilent J&W GC columns, ensuring analytical precision, low bleed, and dependable column-to-column reproducibility for your lab workflows.

Frequently Asked Questions

What are Agilent J&W Standard GC columns used for?

They are used for gas chromatography separations in analytical chemistry, environmental testing, and industrial quality control. Their robust polysiloxane phases provide reliable performance across a wide range of nonpolar and moderately polar compounds.

How do I choose between DB and HP column series?

Both DB and HP columns are manufactured to high-performance specifications. DB columns are optimized for low bleed and reproducibility, while HP series offer identical phase chemistry with alternate labeling for legacy compatibility in Agilent systems.

What does “UltiMetal” mean in CP-Sil columns?

UltiMetal-treated columns feature a deactivated metal surface that prevents adsorption of active compounds and improves inertness, particularly beneficial for trace-level or highly reactive analytes.

Are these GC columns compatible with all instruments?

Yes. Agilent J&W columns use standard 1/4-inch or 1/8-inch ferrule connections, making them compatible with most major GC instrument brands, including Agilent, Thermo Fisher, Shimadzu, and PerkinElmer systems.
