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

Hi,

 

I am using a ZB-WAXplus column that is causing some degradation to one analyte as it passes along the column.

 

Can anyone suggest a WAX type column phase that has an even more INERT column material?

 

(There was also some thermal degradation in the inlet - but I have fixed this by lowering injector temperature from 250C to <180C - so I am only worried about degradation occurring while the analyte passes along the column.)

 

Cheers,
