Hi, everyone!
Is Hypersil AA-ODS 79916AA-572 column actually an (AC) column?
I can see on a web site it is:
If it is I should use in-column-hardware-fit guard cartridges 7992618-504 Hypersil ODS, 5 µm, 4 x 4 mm cartridge (AC), 10/pk (use with hardware kit 5021-1845).
The question arised as I can see elsewhere a totally different information, it is standalone column and a standalone Thermo-style guard holder (Female-Female, connecting capillary required) with cartridges:
And it looks like a standalone column on ebay:
