HPLC Guard Columns and Cartridges
Waters Corp BioSuite Diol (OH) Guard Column, 4 µm, 4.6 mm X 35 mm, 10K - 500K, 1/pk
BioSuite SEC Columns are available in 4.6 mm, 7.5 mm, and 7.8 mm i.d. analytical and 21.5 mm i.d. preparative and guard columns.
Optimize Technologies OPTI-GUARD™ 1mm Guard Column, C4, 5pk
OPTI-GUARD™ sets the standard for extremely low impact, easy to use pre-column protection. Designed for use with analytical (4.6, 3.0 mm i.d.) and narrow-bore (2.1, 1.0 mm i.d.) columns, the patented floating stem design automatically adjusts to any manufacturer's tube stop depth for a zero-dead-volume connection every time. The best part? It's no larger than a standard fitting. Connecting the OPTI-GUARD™ requires no extra tubing, maintaining the minimal impact philosophy that has made the OPTI-GUARD™ line so popular. As always, custom packing is available. Key Features include: 5 disposable hand-tight holders and cartridges, a ZDV Connection, automatic adjusting to any manufacturer's column, no extra tubing is required for connection, the product does not effect chromatography, and it is no larger than a standard fitting.
Sepax Technologies Inc Sepax HPLC Column Bio-C18, Guard cartridge with holder, 5 µm, 300 Å, 2 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.
Sepax Technologies Inc Sepax HPLC Column GP-C4, 5 µm, 120 Å, 2 x 10 mm
Monomeric and fully endcapped GP-C4 packing is bonded with butyl groups that lead to moderate hydrophobicity. GP-C4 columns have unique selectivity and peak symmetry with moderate retention for separations of acidic, neutral and basic organic compounds, such as pharmaceuticals, peptides, and organic acids.
Sepax Technologies Inc Sepax HPLC Column Antibodix WCX, NP10, 2 x 10 mm
Antibodix columns are specially designed for high resolution, high efficiency and high recovery separations of antibodies. The packing support is composed of a rigid, spherical, highly cross-linked poly(styrene divinylbenzene) (PS/DVB) non-porous bead. The non-porous resin has particle size of 1.7, 3, 5 and 10 µm. The PS/DVB resin surface is grafted with a highly hydrophilic, neutral polymer thin layer with the thickness in the range of nanometer. On the top of the hydrophilic layer, weak cation-exchange functional groups are attached via a proprietary chemistry, resulting in high capacity ion-exchange layer.

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.
Sepax Technologies Inc Sepax HPLC Column HPLC Guard Column, SRT SEC-2000, 5 µm, 7.8 x 50 mm, Light Scattering SEC
Utilizing proprietary surface technologies, SRT SEC phases are made of the uniform, hydrophilic, and neutral nanometer thick films chemically bonded on the high purity and enhanced mechanical stability silica. This proprietary surface technology results in excellent column-to-column reproducibility. The nature of the chemical bonding and the maximum bonding density of the thin film benefit SRT SEC phases with high stability and negligible non-specific interactions. Along with the widest pore size selection of 100, 150, 300, 500, 750, 1000 and 2000Å, SRT SEC packings have highest capacity that enables highest resolution.
Waters Corp Viridis BEH VanGuard Pre-column, 130Å, 3.5 µm, 2.1 mm X 5 mm, 3/pk
The Viridis sub-2-µm and 3.5 µm columns demonstrate high efficiency and resolution. The reduction and control of surface silanol activity on Viridis particles delivers, under SFC conditions, excellent peak shapes — without the use of mobile-phase additives — even for well-retained basic achiral compounds.
