The story behind Agilent J&WAdvanced GC Columns


In 2000, Agilent Technologies, the inventor of fused silica GC tubing, merged with J&W Scientific, the creator of the first GC stationary phase made from cross-linked siloxane polymers.


Now, thanks to this partnership, you can find both the renowned HP and DB column families under one name. All brought to you by Agilent Technologies – a company with over 40 years of gas chromatography experience.


Introducing the newest Agilent J&W GC Columns


Agilent J&WUltra Inert GC Capillary Columns Agilent J&W Ultra Inert GC Columns allow you to perform trace level analysis – including the analysis of acids, bases, or other active compounds – with the utmost confidence. What's more, Agilent has set a new industry standard for column inertness testing by introducing a new Ultra Inert Test Probe Mixture that surpasses our most stringent demands for bleed, sensitivity, and efficiency. Agilent J&W Ultra Inert GC Columns are the only GC columns that deliver on the promises of consistent column inertness performance and exceptionally low column bleed for greater sensitivity, better peak shape, and more reliable results. So you can be sure that they will meet the rigorous requirements of today's demanding applications.


Agilent J&WHigh Efficiency GC Capillary Columns Agilent J&W High Efficiency GC Capillary Columns are ideal for fast chromatography where speed, while maintaining resolution, is the most important attribute of the columns. The columns can be applied to any applications that require reduced analysis time, such as high throughput screening, fast process monitoring, fast QC analyses, and fast method development. Agilent J&W High Efficiency GC Capillary Columns are suitable for a wide variety of sample matrices, including environmental, petrochemical, flavor/fragrance, clinical toxicology, or pharmaceutical samples.


The best low-bleed columns for sensitivity and performance. Column bleed can decrease spectral integrity, reduce uptime, and shorten column life. But Agilent J&W columns have the widest range of low-bleed standard and stationary phases featuring superior inertness and high upper temperature limits – especially for ion trap MS users.


Better precision for better results. Agilent J&W columns adhere to tight retention factor (k) specifications, promoting consistent retention and separation. They also feature narrow retention indexes and a high number of theoretical plates per meter, ensuring narrow peaks and improving the resolution of closely eluting peaks.


The industry’s tightest quality control specifications. Agilent’s stringent testing ensures reliable qualitative and quantitative results – even for your most challenging compounds. For example, we measure peak height ratios for both acids and bases to ensure top performance for the widest range of compounds.We also monitor peak symmetry and tailing for a broad scope of chemically active compounds.
