GC Columns
EZ-Guard™
New integrated GC column protection for easy and trouble
free operation
| · |
No column coupling |
| · |
No leaks |

No issues with dead volume, thermal capacity and fragility |
| · |
No hassle in getting the guard column on and off the column
cage |
Guard columns (retention gaps) are often added to the front of
the analytical column for protecting for contamination or to act
as band focusing device when introducing a liquid sample into the
capillary (with on-column and splitless injection techniques).
The Varian EZ-Guard column is combination of a FactorFour
column with a built-in Varian made guard column. The first 5- or 10-meter
part of the EZ-Guard column is not coated with stationary phase
but has been deactivated. So no column coupling which results in
a 100% leak-free connection. Problems with installation, peak shape
and leaks are history!
But there’s more! Besides the generic benefits from an integrated
guard column, Varian EZ-Guard column offers:
| · |
Faster
stabilization in ms and other detection systems due
to an additional uncoated, deactivated section at the end |
| · |
Trouble-free trace analysis of “difficult” compounds
due to the high inertness of the FactorFour columns |
| · |
It is easy
to take off a contaminated part because of
the clearly visible EZ-Guard indication on the EZ-GRIP™ cage |
The Varian EZ-Guard column is based on the FactorFour
technology offering the lowest bleed specifications available; column bleeding
is minimized so all the benefits
of low bleed are provided.
The EZ-Guard
columns come 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.
