HPLC/UV of Nitrite, Nitrate and Bromide

I need to analyze NO2-, NO3- and Br-. Previously I used Supelco SAX column, that was pretty stable and provided a good resolution. Supelco moved from this column to Supelco SAX 1 one, which does not separate Br- & NO3-. Can anybody recommend me a column for this separation?
