Alternatively, you can always by a similar regular column with the resin of
your choice, empty it and use the slurry to pack your own capillary columns
using a NanoBaume high pressure packing device.

I second that query. nanoLCMS.com also went out of business and they were my
go-to supplier.

Hi ABRFers:
Our vendor the Nest Group has stopped the C18 packing materials for
proteomics capillary columms. Does anyone have recommendations for
alternatives? Thanks!
Susie
