Agilent J&W GC and GC/MS Columns
The Tightest QC Specs in the Business
Agilent makes more capillary GC columns than anyone else in the world, and we build them to meet consistently rigid performance criteria,
such as separation efficiency, retention characteristics, peak height ratios, and bleed rates.
Agilent's stringent QC performance evaluation tests provide the utmost confidence in the qualitative and quantitative results, especially
for difficult-to-chromatograph compounds. We measure peak height ratios for acidic and basic compounds to ensure the highest column
performance for the widest range and types of compounds. We also carefully monitor peak symmetry and tailing for a broad range of
chemically active compounds.
