HPLC analytical column LUNA C18 (2) (octadecyl chemically bonded to pure silica), stable between pH 1.5 and 10.
Dimensions: 250 x 4.6 mm. Cat OOG-4252-EO Phenomenex.

is equivalent to C18-4E ?

Answer
No. first thing you should take a look is their pH ranges.
Luna is a hybride type and has wider working pH range than silica.
So we should go for 1. Asahipak C8P-50 4E and 2.ODP50 4E.
But even them, pH range is 2-13. I believe that will be good enough, but if they need to work at pH 1, could use RP18-413 (4.6x150mm, 3.5 um, 200A).
