Features

VF-5ms GC Columns

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. This selectivity, combined with superior inertness, also makes these columns applicable for a wide range of semipolar and even polar components, such as phenols.

Highly inert 5% phenylmethyl column for increased sensitivity, accuracy and instrument uptime
Minimal column bleed improves sensitivity – ultra low bleed specification of 1 pA @ 325 °C (30 m x 0.25 mm, 0.25 μm)
Slightly higher polarity than VF-1ms, results in improved selectivity for aromatic compounds; selectivity and excellent inertness make these columns applicable for a wide range of semi-polar and even polar compounds
0.15 mm id columns available for high efficiency GC and GC/MS analyses
QC test results for retention index, efficiency, selectivity and bleed is reported with every column
Supplied with EZ-GRIP to simplify column installation, coupling and operation

VF-5ht GC Columns

Agilent J&W VF-5ht improves the analysis of high boiling compounds with low-bleed performance, even at high temperatures. Based on ultra-low-bleed technology, VF-5ht provides unmatched selectivity, sensitivity, and accuracy for the analysis of high molecular weight compounds. Temperature limits -60 to 400 °C for fused silica and -60 to 450°C for Ultimetal stainless steel.

Enhanced stability improves column longevity and reduces downtime
Superior detector performance provides improved detection limits
For analyses of high boiling compounds by exhibiting ultra low bleed at high temperatures
Optimized sensitivity and accuracy for analysis of high molecular weight compounds
Identical selectivity as VF-5ms (bleed spec of 30 m x 0.25 mm column is < 5 pA at 400 °C)
UltiMetal technology renders the stainless steel inert and enhances bonding of the stationary phase for improved column lifetime and excellent peak shape

VF-5 Pesticides Columns

Agilent J&W VF-5 Pesticides columns are specially designed for the determination of trace levels of pesticide residue. Every column is individually tested before shipment with key pesticides, including endrin and aldrin, ensuring optimal performance and consistency of results.

Specially designed for the determination of trace levels of pesticide residue
Highly inert for enhanced ECD and MS detection
Tested with key pesticides including endrin and aldrin for optimal performance and consistency of results
Low bleed

Rapid-MS GC Columns

Agilent J&W Rapid-MS columns reduce analysis duration by three to five times for temperature programmed, and up to a 10 times for isothermal runs. The film thickness from 0.1 to 1 µm ensures high loadability and the higher sensitivity typically increases the signal-to-noise ratio by a factor of three or greater.

Equivalent to 5% phenyl, 95% dimethylpolysiloxane
Fast analysis time improves productivity
Reduce analysis time by 3-5x for temperature programmed, and up to a 10x for isothermal runs
The film thickness from 0.1 to 1 μm ensures high loadability and higher sensitivity
Low bleed
Rapid-MS columns utilize the high optimal carrier gas velocity obtained when a separation is performed under reduced pressure for fast analysis times
