Alternative capillary column to 30% G22 phase support S1D

in ether USP monograph (2-mm × 3.7-m stainless steel; with 30% phase G22 on 30- to 60-mesh support S1D) is required for "Limit of Low-Boiling Hydrocarbons" analysis but it is packed column,  and we want to find alternative capillary column.

Thanks in advance.
