Sepax Technologies Inc Sepax HPLC Column Bio-C8, Guard cartridge with holder, 3 µm, 300 Å, 2 x 10 mm
Bio-C8 phase is made of monomeric and fully endcapped chemistry. The uniform stationary phase allows the separation to achieve high selectivity and high efficiency. Bio-C8 packings of 300 Å pore size selection are ideal for high resolution mapping of peptides and separation of natural and synthetic peptides and small proteins.
Sepax Technologies Inc Sepax HPLC Column Proteomix SAX, NP10, 10 x 50 mm
Sepax HPLC Column Proteomix SAX, NP10, 10 x 50 mm
Waters Corp DeltaPak C18 Guard Column, 100Å, 5 µm, 10/pk
Delta-Pak packings, ideal for the separation of peptides, proteins, and natural products, are based on a highly stable, bonded, endcapped 5µm or 15µm spherical silica. Delta-Pak is available in two different pore sizes (100Å and 300Å) with either C4 or C18 bonded phase. Delta-Pak packings are available in different cartridge and column configurations, providing consistent and predictable scale-up capabilities for milligram-to-gram scale purification. Also, by having the same chemistry available on a high-efficiency 5µm particle, you can easily check the purity of your fractions.
Waters Corp Atlantis T3 Prep Guard Cartridge, 100Å, 5 µm, 10 mm X 10 mm, 1/pk
Atlantis T3 columns are universal, silica-based, reversed-phase C18 columns that provide balanced retention of polar and hydrophobic molecules and should be your first choice when developing separations of polar and non-polar compounds.
Waters Corp Nova-Pak Phenyl Sentry Guard Cartridge, 60Å, 4 µm, 3.9 mm X 20 mm, 2/pk
Nova-Pak HP Phenyl columns are based on 4 µm silica-based particle technology. The phenyl ligand is used to achieve unique compound selectivity with reversed-phase applications.
Waters Corp XSelect CSH Fluoro-Phenyl Prep Guard Cartridge, 130Å, 5 µm, 19 mm X 10 mm, 1/pk
Designed to maximize selectivity differences, the XSelect CSH Fluoro-Phenyl column provides you with maximum method development freedom, especially when using low pH mobile phases. The non-encapped sorbent provides you with enhanced retention of acidic compounds.
Tosoh Bioscience LLC TSKGEL AMIDE-80 GUARD COLUMN
Column, Guard; For 21.5mm I.D. Tosoh TSKgel Amide-80 column; Media: Silica; 21.5mm I.D. x 7.5cm Length
Sepax Technologies Inc Sepax HPLC Column Proteomix SAX, NP10, Guard cartridge (No Holder), 2 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.
Sepax Technologies Inc Sepax HPLC Column PolyRP-500, Guard cartridge with holder, 5 µm, 2 x 10 mm
GP-C8 phase is synthesized with monomeric and fully endcapped chemistry. The uniform octyl stationary phase allows high efficiency with lower hydrophobicity compared to ODS phase. GP-C8 phase is suitable for separating compounds with a wide range of hydrophobicity. It is highly recommended for separating the compounds which are too strongly retained on C18 phases.

Waters Corp Symmetry Shield RP18 Prep Guard Cartridge, 100Å, 5 µm, 19 mm X 10 mm, 1/pk
These reversed-phase columns contain Waters patented embedded polar group technology that “shields” the silica’ residual silanol surface from highly basic analytes. The reduced silanol activity for the SymmetryShield RP18 column significantly improves peak shape and resolution. This product needs to be used in conjunction with other parts.
