The ARE-Applied Research™ brand of column couplers are used to connect the flow of two HPLC columns or a guard column and an analytical column directly in series.
Below is our recommended selection chart to match your flow rate and a suggested union-column coupler (ID). The ID of the coupler should be determined based on your application, where the faster the flow, the larger the bore (ID) is needed.
