Agilent - GC Columns

Agilent J&W GC columns are available in a wide variety of stationary phases, offering a solution for your gas chromatography analysis.

Agilent J&W GC columns help lab analysts maintain the highest standards of performance. The columns deliver industry-leading technology with the highest inertness, lowest bleed levels, and tightest column-to-column reproducibility specifications. We offer specific GC columns for the Intuvo 9000 GC, columns for the 8890 GC that have a Smart Key included as well as Low Thermal Mass columns and packed GC columns for applications such as hydrocarbon processing. If a column is required that isn't part of our standard offering, a custom GC column can be built to order.

Key features

With the highest inertness, lowest bleed levels, and the tightest column-to-column reproducibility, Agilent J&W GC Capillary columns perform better than any columns on the market.

  • Ultra inert Columns – allow you to perform trace level analysis – including the analysis of acids, bases, or other active compounds – with the utmost confidence. They also help ensure an inert GC flow path that is essential for sensitivity, performance, and the integrity of your analytical results.
  • Llow-bleed GC/MS Columns – are specifically designed to chromatograph a broad range of trace-level samples, and offer low bleed and high inertness even at higher temperatures.
  • Premium Polysiloxane Columns – are stable, robust, and versatile and are available in a wide variety of stationary phases.
  • Polyethylene Glycol (PeG) Columns – offer a variety of unique phase characteristics to meet the varying needs of your laboratory, thanks to Agilent’s strict quality control of the cross-linking and deactivation processes.
  • Specialty Columns – meet Agilent’s uncompromising standards for high-temperature, life science, pesticide, petroleum, semivolatile, and volatile applications.
  • Plot Columns – deliver superior separation for compounds that are gases at room temperature. They are also ideal for analyzing fixed gases, low molecular weight hydrocarbon isomers, volatile polymer compounds, and reactive analytes such as gases, amines, and hydrides.

Low-bleed GC/Ms columns

There is a rapidly increasing population of benchtop GC/MS instruments in analytical laboratories that analyze a widening range of trace level, higher temperature samples. These samples require increasingly inert, lower bleed, higher temperature columns. In response to this growing need, Agilent Technologies designed several "ms" columns to chromatograph a broader range of low level samples and generate lower bleed even at higher temperatures.

What makes an Agilent J&W low-bleed column exceptional? Unique polymer chemistry and proprietary surface deactivation, both of which have contributed to columns that adhere to the tightest quality control specifications in the industry for bleed, inertness, selectivity and efficiency. Agilent J&W "ms" columns utilize special surface deactivation and siloxane chemistries which enhance the chromatographic performance of siloxane polymers.

The mass spectrum of septum bleed can look very much like GC column bleed, so the two are often confused. An easy way to tell the two apart: column bleed will be indicated by a rise in the baseline, not peaks. If you see bleed peaks, these generally come from lower quality septa or septa being used beyond their operating limits. To minimize septa contributions to background bleed, use quality Agilent BTO, Long-Life, or Advanced Green septa.

Life sciences columns

The life sciences offer some difficult challenges to capillary GC chromatographers. These include complex sample matrixes, the necessity for low level detection and the chemically active characteristics of many of the samples. In response to this, Agilent offers a line of columns which are designed specifically for drugs of abuse testing.

DB-AlC1 and DB-AlC2

  • Reliable blood alcohol analysis
  • Optimized primary and confirmation column pair for US blood alcohol analysis
  • DB-ALC1 and DB-ALC2 columns are regularly used in sets. Connect them together easily with an Agilent Ultra Inert, universal press fit Y-splitter (5190-6980), or an UltiMetal Plus deactivated CFT un-purged splitter (G3184-60065)
  • Faster GC run times
  • Improved resolution of key ethanol/acetone peaks
  • Available in 0.32 and 0.53 mm id
  • Bonded and cross-linked

Similar phases: Rtx-BAC1, Rtx-BAC2, ZB-BAC-1, ZB-BAC-2

PloT Columns

PLOT columns are ideal for separating compounds that are gases at room temperatures. Agilent Technologies offers a comprehensive line of PLOT columns for analysis of fixed gases, low molecular weight hydrocarbon isomers, volatile polar compounds and reactive analytes such as sulfur gases, amines and hydrides. Our PLOT phases are offered in dimensions from 0.25 to 0.53 mm id, allowing for easy column selection for various detector and system requirements. For GC/MS systems, we offer several small diameter columns with truly bonded and immobilized stationary phases, eliminating potential detector fouling due to particle generation.

PloT PT

Agilent J&W PLOT PT columns are engineered to improve lab operations. Unlike current techniques used to prevent PLOT stationary phase particles from shedding downstream, the integral particle traps of the PLOT PT columns remove the aggravation of connecting separate traps. Operation is more convenient and there is no risk from leaks. The integrated particle-trapping technology on both ends of PLOT PT GC columns reduces downtime. What’s more, with PLOT PT you can now use GC/MS for detailed, qualitative and quantitative analysis and due to the dual ended particle traps the PLOT PT columns can also be used for backflush applications. No other PLOT column offers this level of worry-free operation for your GC or GC/MS system. Agilent J&W PLOT PT columns are available in porous polymers Q and U, Aluminum oxide and Molesieve stationary phases.

Guard Columns

  • DuraGuard and EZ-Guard columns with "built-in" guard columns, no press-fit connectors
  • Minimize front-end contamination and increase column lifetime
  • Aid in focusing sample onto the front of the column for better peak shape
  • Minimize MSD contamination originating from the column (when used as transfer line to the MS detector)

Guard columns (or retention gaps) are often added to the front of the analytical column to protect against contamination, or to act as a band-focusing device for liquid samples introduced by on-column and splitless injection techniques.

When resolution or response in a chromatogram diminishes, remove a coil from the guard columnso that peak shapes will improve. By removing a coil, the column length is shortened and peaks will elute somewhat faster. For best results, check the integration time windows of your data system.
