GL Sciences HPLC Guard Cartridge InertSustain Phenylhexyl 100Å 3μm, 4.0 x 20mm, 2/PAK, (use Holder GL-5020-08550)

InertSustain Phenylhexyl columns are bonded with phenylhexyl groups, which employs a phenyl ring with a hexyl (6- carbon) linker and is densely bonded to our newly developed ES silica gel delivering complementary selectivity to straight alkyl-chain columns, but with industry leading inertness, lot-to-lot reproducibility and low back pressure.
