GC/MS Columns

GC-MS columns are capillary columns which direct effluent from a sample into a mass spectrometer, where a spectrum of each component is obtained. Bench top GC/MS instruments are becoming increasingly popular in the analysis of a widening range of trace level and higher temperature samples, creating a need for increasingly inert, lower bleed, higher temperature columns.

Agilent J&W DB-624 is recommended for EPA methods 502.2 and 8021, as well as for fast GC/MS volatiles analysis. It is specifically designed for the analysis of volatile priority pollutants and residual solvents.
Agilent J&W DB-1ms is a nonpolar, low bleed column, with excellent inertness for acids and bases and an extended upper temperature limit. Using low bleed stationary phases in DB-1ms reduces column contribution to background noise, resulting in a higher signal-to-noise ratio and better sensitivity.
Agilent J&W DB-XLB has exceptionally low bleed and low polarity. The column delivers highly specific analysis of pesticides, herbicides, polychlorinated biphenyls (PCBs), and polyaromatic hydrocarbons (PAHs).
Agilent J&W DB-17ms delivers excellent levels of inertness for the effective analysis of active compounds. The column is bonded, cross-linked and solvent-rinsable, and excellent for the analysis of pesticides and other semivolatile analyses.
Agilent's precision-engineered DB-1ht columns deliver excellent performance in a range of GC/MS applications and are manufactured to the highest levels of quality and flexibility.
Agilent J&W HP-5ms has very low bleed characteristics that are ideal for GC/MS. The column has excellent inertness for active compounds, including acidic and basic compounds, and improved signal-to-noise ratio for better sensitivity and mass spectral integrity.
Agilent J&W DB-5ms features an excellent signal-to-noise ratio for analytical applications. This improved performance gives better sensitivity and mass spectral integrity. What's more, DB-5ms delivers excellent inertness with active compounds.
Agilent J&W HP-5ms Ultra Inert is specifically tested for inertness for active compounds, including acidic and basic compounds, to meet the worldwide drive for lower detection levels.
Agilent J&W LTM column modules combine a high-quality fused silica capillary column with heating and temperature sensing components for a low thermal mass column assembly.
Agilent J&W VF-5ms is an inert 5% phenyl-methyl column for increased sensitivity, accuracy and instrument uptime. The column has the lowest guaranteed bleed specification of 1 pA at 325 °C (30 m, 0.25 mm, 0.25 µm). VF-5ms has a slightly higher polarity than the VF-1ms, resulting in a better selectivity for aromatic compounds.
