I need a WAX type column that is more inert than ZB-WAXplus

Hi, mrobinson,

I'm no expert on the subject, but this afternoon kssabnis uploaded a new abbreviated App Note that looks like it's related: Analysis of Distilled Spirits Using an Agilent J&W DB-WAX Ultra Inert Capillary GC Column. A couple week ago, there was another one: Lavender Oil Analysis Using Agilent J&W DB-WAX Ultra Inert Capillary GC Columns.

Can you please describe what sort of sample you are analyzing? That ought to help us figure out what sort of chemistry may be going on, and thus what kind of column may be appropriate.

kgl, do you have any guidance regarding different inert and ultra inert columns?

Thanks. - Josh

Hello Murray,

As Josh mentioned, you can try our new DB-WAX Ultra inert GC columns. DB-WAX UI GC columns can  deliver excellent inertness with more reliable peak shape and better longevity performance than many popular WAX columns including ZB-WAX plus. More detailed information, please see application note 5991-6683EN "A New PEG GC Column with Improved Inertness Reliability and Column Lifetime" and 5991-6709EN "DB-WAX UI columns brochure".

Best Regards,

Hi ,

Our colleague the kssabnis just created a new abbreviated document in Application Notes: GC and GC/MS corresponding to that app note (actually a technical overview): A New PEG GC Column with Improved Inertness Reliability and Column Lifetime -Agilent J&W DB-WAX Ultra Inert Polyethylene Glycol Column.

By having this document in the community, any member may comment on it and perhaps have a conversation with the authors.

Enjoy! - Josh
