HPLC Guard Columns and Cartridges
Sepax Technologies Inc Sepax HPLC Column HPLC Guard Column, SRT SEC-2000, 5 µm, 4.6 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.
Optimize Technologies OPTI-GUARD™ 1mm Guard Column, Method Development Kit, 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. This product allows you to pick 5 different cartridge packings for test and trial purposes.

Optimize Technologies EXP™Guard Column Cartridge, 4.6mm x 5mm, C4, 3µm, 3pk
The EXP™ Guard Column cartridge system is rated to 15,000psi with hand-tight replaceable cartridges. This unique design connects directly to any UHPLC column with the auto-adjusting Titanium Hybrid Ferrule and EXP™ Fittings, providing repeated zero-dead-volume connections and easy adjustability between various column types. Free-Turn™ architecture allows the user to change cartridges by hand without breaking fluid connections on the holder inlet/ outlet. The combination of low-dispersion and ultra high-pressure capabilities provides effective protection with negligible effects on retention time, plate count, and peak shape. Use with EXP™ Direct Connect and In-line Holders.
Waters Corp Viridis BEH VanGuard Pre-column, 130Å, 1.7 µm, 2.1 mm X 5 mm, 3/pk
Designed and tested for the ACQUITY UPC2 system, 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.
Waters Corp XBridge Peptide BEH C18 Prep Guard Cartridge, 130Å, 10 µm, 19 mm X 10 mm, 1/pk
The XBridge BEH130 C18 Peptide Separation Technology columns are optimized and QC tested for peptide separations. The small-pore (130Å) trifunctionally bonded BEH particle offers you the widest usable pH range, superior low pH stability, and ultra-low column bleed to assay samples for proteomics, protein characterization, and peptide synthesis.
Waters Corp XBridge Peptide BEH C18 Prep Guard Cartridge, 300Å, 10 µm, 10 mm X 10 mm, 1/pk
The XBridge BEH300 PREP C18, 10 µm, 10 x 10 mm Guard Column was develeped and designed to extend the life the BEH130, C18, 10um, 10mm ID preparative column. The BEH300 PREP C18, 10um packing material used in the Guard Column must also pass the peptide digest, QC test criteria established for the prep column.
Waters Corp XTerra Phenyl VanGuard Cartridge, 125Å, 3.5 µm, 2.1 mm X 5 mm, 3/pk
XTerra Phenyl VanGuard Cartridges are used to extend analytical column lifetime and performance by removing particulate contamination from the mobile phase stream. This cartridge is optimized to protect all 2.1 mm and 3.0 mm I.D. XTerra Phenyl analytical columns containing 3.5 µm sorbent particles.
Sepax Technologies Inc Sepax HPLC Column GP-C4, 3 µm, 120 Å, 4 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 Proteomix WAX, NP5, Guard cartridge with holder, 4 x 10 mm
Proteomix ion-exchange phases have been innovatively developed for achieving high ion-exchange capacity, a breakthrough technology for non-porous resins. Proteomix packing support is composed of a rigid, spherical, highly cross-linked poly(styrene divinylbenzene) (PS/DVB) non-porous bead with particle size selections 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. The hydrophobic PS/DVB resin surface is totally covered by a hydrophilic coating that eliminates non-specific bindings with biological analytes, leading to high efficiency and high recovery separations for biological molecules.
