Agilent J&W GC and GC/MS Columns
The Industry's Best Low-Bleed and Most Inert Columns
Column bleed can decrease spectral integrity, reduce uptime, and shorten column life. Column
activity contributes to severe peak tailing, as well as compound loss or degradation for active
compounds (e.g. acids and bases), leading to inaccurate quantification. Agilent J&W columns
have the widest range of GC/MS and Ultra Inert stationary phases proven to deliver consistent
column inertness and exceptionally low column bleed with high upper temperature limits,
ensuring accurate peak identification and quantification.
Why low-bleed columns are a smart choice
If you perform trace analyses where sensitivity and instrument performance are important,
column bleed (or the lack thereof) should be important to you. Many GC detectors are
sensitive to contamination from bleed. By using low-bleed columns, these detectors require
less maintenance. Due to the unique relationship between ion storage capacity of the trap
and sensitivity levels, ion trap MS users will especially benefit from low-bleed columns.
What makes Agilent J&W low-bleed columns so special?
In short, it's Agilent’s unique polymer chemistry and proprietary deactivation. Our MS
columns utilize special surface deactivation and siloxane chemistries that enhance the
chromatographic performance of siloxane polymers. To provide selectivities virtually identical
to their conventional counterparts, we offer DB-5ms, DB-35ms, DB-17ms, and DB-225ms.
The HP-5ms uses the same stationary phase as the standard HP-5, providing low bleed
without the use of arylene technology. DB-1ms and HP-1ms provide the same selectivity
as the standard 100% dimethylpolysiloxane (DB-1) type column. Plus, our unique DB-1ms
polymer chemistry and proprietary deactivation techniques help us increase temperature
limits (340/360°C), improving thermal stability and optimizing performance.
