RMX GC Columns FAQs
RMX GC columns with TriMax deactivation technology maximize trace-level performance, so you can increase productivity and profitability. Exceptional inertness delivers superior peak symmetry across a wide range of challenging active compounds, resulting in more linear calibrations and higher recoveries.
RMX GC columns are made with TriMax technology, a groundbreaking deactivation that produces an exceptionally inert surface free of the residual active sites left behind by traditional deactivations. TriMax deactivation creates a rugged, contaminant-free surface that ensures outstanding peak shape and sensitivity, even for active compounds, such as acids, bases, alcohols, and more.
RMX GC columns are available in a wide range of formats and dimensions. Find the right one for your application.
