Sepax Technologies Inc Sepax HPLC Column HPLC Guard Column, SRT-C SEC-2000, 5 µm, 4.6 x 50 mm, Light Scattering SEC
SRT-C SEC phase, developed based on innovative surface coating technology, comprises of uniform, hydrophilic, and neutral nanometer thick film chemically bonded to high purity and mechanically stabilized silica. SRT-C, uses lay-down monolayer on porous silica as oppose to SRT of stand-up monolayer, offers ideal phase chemistry for hydrophobic samples like insulin, membrane protein monoclonal antibodies derivatized with polymer branches (polypeptide or PEG) separation.
YMC America, Inc C4 guard 200A 10um 10x4mm
YMC-Pack C4 is ideal for analyzing mixtures with a wide range of component polarity This is due to the C4 bonded phase exhibiting shorter analysis time while still maintaining high resolution when compared to longer-chain bonded chemistries YMC-Pack C4 (Butyl) columns are available with three pore sizes to accommodate optimum separations of virtually any molecular-weight compound The 120 phase is used extensively with non-polar peptides which are too strongly retained on C8 and C18 The 200 and 300 phase columns effectively resolve many classes of proteins and biopolymers
