What are the differences between the ZB-Wax and ZB-WaxPlus?

The ZB-WaxPlus phase is made of a lower molecular weight polymer that has liquid character at lower temperature than the original ZB-Wax.

The unique bonding of the lower molecular weight PEG polymer in ZB-WaxPlus allows it to be used with 100% aqueous samples, without inconsistencies from injection to injection, and gives better selectivity for low boiling point compounds. The ZB-WaxPlus tends to give better peak shape for acids while the original ZB-Wax gives better peak shape for basic compounds.
