I need ways to do more with what I have now

Whether you re screening for organic contaminants or working with semivolatiles, chances are good that you may be able to improve the speed of your method with Agilent J&W High Efficiency Columns.   Agilent High Efficiency columns are available in the same phase you re currently using, but the combination of a narrower diameter and shorter length creates efficiency that cuts run times, without impacting resolution.

Here are the highlights:

• Agilent J&W High Efficiency columns help you to decrease your run time by 30% - 90%.  Actual time improvements will depend on the carrier gas and column dimension you re transferring from.
• Save on your carrier gas usage as much as 40%.  The High Efficiency columns work with helium and hydrogen carrier gases.
• Method modification is rapid and easy with FREE downloadable Method Translation software.

With 65 part numbers and 23 stationary phases, Agilent has the largest selection of High Efficiency GC Columns for the widest range of applications. When moving to a column with narrow ID, your sample capacity is reduced.  For dirty samples, consider using a guard column, or the Duraguard column, which combines guard column protection as part of one column unit.
