The bonded phase in SRT™-C SEC columns is more polar than the hydrophilic phase used in SRT™ columns, making SRT™-C columns better suited for the gel filtration analysis of more hydrophobic bioopolymers such as membrane proteins and pegylated antibodies.
Kits include one cartridge, a stand-alone holder, a piece of tubing, and 2 nuts and ferrules. Guard cartridges require holders that are sold separately.
CHIRALPAK™ HSA, which uses human serum albumin as the chiral selector, is highly selective for acidic racemates, preferably weak and strong acids, zwitterionic and non-protolytic (neutral) compounds.
Designed for the analysis of environmental analytes (such as semivolatiles, pesticides, PCBs, and herbicides) or anywhere a low bleed non-polar column is required.
SUPELCOSIL™ LC-18-S Supelguard™ Cartridges contain a SUPELCOSIL™ packing, in a 2 cm stainless steel body, enclosed by polyether ether ketone (PEEK) encapsulated stainless steel frits.
