GC Columns

New: 0.15 mm ID VF-Xms columns for
faster GC and GC/MS




VF-Xms:
The GC column with the highest temperature stability of any low bleed optimized phase

· lowest bleed possible, so all the benefits of low bleed are provided
· up to a factor 4 lower bleed then the other manufacturers equivalents and up to a factor 8 lower then the 5ms type phase from other manufacturers
· ideal for confirmational analysis
· highest temperature stability of any “MS”-optimized phase, allowing isothermal applications up to 340°C
· quick and accurate elution of components with high boiling points

Compared to non-polar “ms” type phase, the VF-Xms shows exceptionally high selectivity for pesticides and provides high resolution in the shortest analysis time. (see application note: Analysis of chlorinated pestcides (.pdf, 27kB))

The VF-Xms comes with an EZ-GRIP™ simplifying installation, coupling and operation of capillary columns. For guaranteed performance the retention index, efficiency, selectivity and bleed is measured and specified on the test report supplied with each column.

Typical components analyzed with the VF-Xms include:
pesticides, herbicides, PCBs, PAHs

Similar phases:
DB-XLB, MDN-12

The VF-Xms cross-reference guide on part number level helps you to select the VF-Xms column for the column you are currently using.
