Hello,

Is anyone analyzing perchlorate via EPA 314.0 on a Metrohm IC? I'm trying to find a setup that would work for my lab.

I was provided an application by Metrohm that used an A Supp 19 150/4.0 column, but the eluent had 45% acetonitrile in it. The column's ability to withstand eluents with that level of solvent seemed overstated, as I was experiencing column damage within a month of use.
