I'm pretty new to the GC world in general. My 7890 unit came with a set of wrenches and I never bothered to take note of what their sizes were. Someone took my wrenches recently and I cannot find them. I need to order some new wrenches, but I have no idea what sizes would be useful for doing routine work on a GC.
Looking through their website, Agilent has many sized wrenches and I have no clue which ones are needed to do simple tasks like replace a GC column and ferrules. Can someone please let me know what size wrenches I should get for use on a 7890 GC?
