Sepax Technologies Inc Sepax HPLC Column BR-C18, Guard cartridge replacement, NO holder, 1.8 µm, 120 Å, 2 x 10 mm
Utilizing highest purity and enhanced mechanical stability silica and pure bonding reagents, BR-C18 bonded phases have been innovatively and specially designed to ensure maximum surface coverage and full end-capping, which leads to carbon content as high as 19.0%. The bonding chemistry is completely controlled that results in very reliable column-to-column reproducibility. The maximum surface coverage allows BR-C18 to have exceptional stability, resulting in high pH stability in the range of 1.5 to 10.5.
Waters Corp ACQUITY UPLC Protein BEH SEC Guard Column, 125Å, 1.7 µm, 4.6 mm X 30 mm, 1K - 80K, 1/pk
This guard column kit contains an advanced, ultra-low volume guard device (4.6 mm ID x 30 mm) containing BEH125, SEC, 1.7ìm particles and guard connection tubing (0.005” x 1.75”) designed specifically for use in UPLC SEC applications up to 6000 psi (400 bar).
Sepax Technologies Inc Sepax HPLC Column Proteomix HIC Butyl-NP5, Guard cartridge with holder, 4 x 10 mm
Proteomix HIC columns are specially designed for high resolution and high efficiency separations of proteins, monoclonal antibodies (mAbs), antibody drug conjugates (ADCs), oligonucleotides and peptides via a hydrophobic interaction chromatography (HIC) mechanism. Utilizing proprietary surface technologies, Proteomix HIC-NP resin is made of non-porous polystyrenedivinylbenzene (PS/DVB) beads with narrow-dispersed particle size distribution. As shown in figure below, the PS/DVB bead is modified with alkyl groups or aryl groups that provide hydrophobic interaction with analytes. Proteomix HIC-NP resin is highly rigid and mechanically stable. In comparison to silica-based HIC phase media, Proteomix HIC-NP phases have advantages for biomolecule separations with a wide pH range (2-12) and high chemical stability.
Sepax Technologies Inc Sepax HPLC Column Bio-C18, 3 µm, 300 Å, 4 x 10 mm
Wide range of pore sizes and high compatibility with 100% aqueous phases make Bio-C18 columns ideal for high resolution mapping of peptides and separation of natural and synthetic peptides and small proteins. The specially designed surface bonding chemistry and the pore sizes allow for extended retention and selectivity for polar and hydrophilic compounds, such as peptides and amino acids. C18 monolayer formed by special bonding chemistry does not collapse in pure aqueous solution.
Advanced Materials Technology HALO 90 Å PCS Phenyl-Hexyl, 2.7um, 4.6 mm x 250 mm
Built upon proven Fused-Core technology for speed and efficiency, the HALO PCS column products are positively charged surface chemistries designed to deliver improved peak shapes for basic compounds observed with standard Phenyl-Hexyl chemistry. Ideal for use with low ionic strength mobile phases, HALO PCS maintains peak symmetry at higher loading capacities and provides alternate selectivities from Phenyl-Hexyl bonded phases. The columns are optimized to deliver performance for reproducible, high efficiency LC and LCMS separations.

Waters Corp ACQUITY UPLC BEH HILIC VanGuard Pre-column, 130Å, 1.7 µm, 2.1 mm X 5 mm, 3/pk
ACQUITY BEH HILIC columns contain unbonded BEH substrate and are designed to retain and separate very polar compounds. These unique columns are optimized and tested to produce efficient, reproducible separations under HPLC HILIC conditions. More rugged than silica based HILIC phases, the BEH particle’s chemical stability results in long column lifetimes. The VanGuard pre-column connects directly to the inlet of the ACQUITY UPLC column which minimizes extra columns volumes and reduces leaking by eliminating additional connections.
Waters Corp ACQUITY UPLC HSS C18 VanGuard Pre-column, 100Å, 1.8 µm, 2.1 mm X 5 mm, 3/pk
ACQUITY UPLC HSS C18 chemistry is an ultra-performance general purpose C18 bonded phase that provides superior peak shape for bases, increased retention (vs. ACQUITY UPLC BEH C18 columns), and extremely long column lifetimes at low pH. ACQUITY HSS C18 columns are fully scalable and transferable to HPLC separations. The VanGuard pre-column connects directly to the inlet of the ACQUITY UPLC column which minimizes extra columns volumes and reduces leaking by eliminating additional connections.
