HPLC Guard Columns and Cartridges
Waters Corp XBridge Peptide BEH C18 Prep Guard Cartridge, 300Å, 5 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 BEH300, C18, 10 µm, 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 SunFire C18 Prep Guard Cartridge, 100Å, 10 µm, 19 mm X 10 mm, 1/pk
SunFire C18 columns are used for general purpose method development at low pH. The C18 ligand is highly retentive, especially for basic compounds and it is ideally suited for purification and impurity profile assays.
Sepax Technologies Inc Sepax HPLC Column Proteomix SCX, NP1.7, 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.
Waters Corp BioResolve RP mAb Polyphenyl VanGuard Cartridge w/holder, 450Å, 2.7 µm, 2.1 mm X 5 mm, 3/pk
BioResolve RP mAb Columns contain 2.7-μm superficially-porous-silica particles having an average pore diameter of 450Å. The particles are functionalized with a proprietary polyphenyl bonding process that was specifically designed for LC or LC-MS analyses of intact IgG monoclonal antibodies and their fragments. This Part Number contains (3) VanGuard Cartridges as well as an included VanGuard Universal Cartridge Holder (P/N 186007949).
Waters Corp SunFire C8 Sentry Guard Cartridge, 100Å, 5 µm, 2.1 mm X 10 mm, 2/pk
SunFire C8 columns are used for general purpose method development at low pH. The C8 ligand is preferred for some assays because it is less hydrophobic and therefore less retentive compared to SunFire C18.
Mac-Mod Avantor Alltima C18, 100 Å, 5 µm, 4.6 x 7.5 mm Guard Cartridges (3/pk)
vantor Alltima columns combines a range of different phase chemistries with base deactivated silica. Avantor Alltima columns provides stable bonding for long column lifetimes. Avantor Alltima columns are made of high purity silica that provide excellent column stability with multiple selectivity options.
Sepax Technologies Inc Sepax HPLC Column HP-Silica, Guard cartridge with holder, 5 µm, 120 Å, 2 x 10 mm
HP-Silica phase is made of activated hydroxyl (-OH) functional group with the pore size selection of 120 Å and particle size selection of 1.8, 3, 5, and 10 µm. Carbon loading is 0.0%. HP-Silica is used as the normal phase as well as HILIC phase. HP-Silica phases are suitable for separations of polar and basic organic compounds, such as vitamins, steroids, as well as pharmaceuticals.
Mac-Mod Avantor Hichrom 100 Å, Guard Holder (ID 7.75 - 21.2 mm)
Avantor Hichrom GC Columns offer over 50 different GC coated capillary phases with proprietary cross-bonding technology that allows column rinsing to increase column lifetime stablizing the phase. In addition to commercially available standard phases, Avantor GC Columns offer specially developed unique phase chemistries. Avantor GC columns are available in High Polarity, Mid-High Polarity, Mid Polarity, Low Polarity and Non-Polar phase chemistries.
Waters Corp XBridge BEH C8 Sentry Guard Cartridge, 130Å, 5 µm, 3 mm X 20 mm, 2/pk
The XBridge BEH C8 sorbent is less retentive compared to the XBridge BEH C18 sorbent. Anyone developing methods may prefer the speed offered by a less retentive column, while improving peak shape and chromatographic performance. The trifunctionally bonded sorbent offers you the widest usable pH range (1-12), superior low pH stability, and ultra-low column bleed.
Mac-Mod HydroBond AQ C8, 100 Å, 3 µm, 3.2 x 10 mm Guard Cartridges (5/pk)
Hydrobond is designed for polar retention of highly polar analytes in RPLC. These columns provide reproducible results, column to column, lot to lot.
Mac-Mod Princeton Imidazole (IMDZ) 100 Å, 5 µm, 4 x 10 mm Guard Cartridges (5/pk)
Princeton Chromatography Achiral SFC columns are designed and manufactured in the US, well known for innovating novel and robust workhorse phase chemistries, for the analysis of achiral SFC applications. Princeton designs myriad phase chemistries to improve the selectivity and efficiency of SFC analysis. Known for originally innovating the 2-EP phase chemistry, explore what Princeton has to offer. Columns are available from analytical to preparative sizes and are available in a wide range of pore sizes, particle sizes, column ID's and lengths.
