HPLC Guard Columns and Cartridges
Sepax Technologies Inc Sepax HPLC Column HP-C18, 3 µm, 120 Å, 4 x 10 mm
HP-C18 uses full coverage bonded silica packing, which provides high stability. Compatible with 100% aqueous mobile phase and suitable for separations of acidic, neutral and basic organic compounds, as well as pharmaceuticals and peptides. ODS monolayer formed by special bonding chemistry does not collapse in pure aqueous solution.
Waters Corp Atlantis T3 Prep Guard Cartridge, 100Å, 10 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 Atlantis T3 Prep Guard Cartridge, 100Å, 5 µm, 19 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 XTerra MS C8 Prep Guard Cartridge, 125Å, 10 µm, 19 mm X 10 mm, 1/pk
XTerra Prep columns bring the benefits of Hybrid Particle Technology to isolation and purification applications in discovery and development laboratories. XTerra Prep MS columns possess our patented Hybrid Particle Technology, with particles engineered specifically for prep. It allows you to routinely operate at pH 1-12 so you can load up to 60X more onto the column. More capacity results in fewer injections for the same amount of pure material or more material with the same number of injections. In the discovery world, this greater capacity means you can use a shorter column, producing the same amount of material in half the time.
Waters Corp Symmetry Shield RP18 Sentry Guard Cartridge, 100Å, 3.5 µm, 3.9 mm X 20 mm, 2/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.
Waters Corp XBridge Peptide BEH C18 Guard Column, 130Å, 5 µm, 10 mm X 10 mm, 1/pk
The XBridge BEH130 C18 Peptide Separation Technology (PST) 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 Symmetry Shield RP8 Sentry Guard Cartridge, 100Å, 3.5 µm, 3.9 mm X 20 mm, 2/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 RP8 column significantly improves peak shape and resolution.
Waters Corp Symmetry C8 Prep Guard Cartridge, 100Å, 7 µm, 7.8 mm X 10 mm, 1/pk
Symmetry columns continues to set the standard for HPLC drug assays, giving you confidence in the long-term compliance of your HPLC methods. No need to compromise on peak shape, selectivity, column-to-column and batch-to-batch reproducibility, or other critical performance characteristics. Available in a variety of particle sizes, chemistries and dimensions.
Waters Corp Waters 125Å SEC Guard Cartridge, MaxPeak Premier, 2.5 µm, 4.6 x 30 mm, 1/pk
Waters 125Å SEC Guard Cartridge, 125Å, 2.5 µm, 4.6 x 30 mm (BEH-DIOL based), with MaxPeak Premier Technology, for use on 1.7 µm and 2.5 µm SEC 125Å columns, was developed for scientists working on biotherapeutic peptides (e.g., GLP receptor agonist and insulin-like)and small proteins ,from approx 1K - 80K Dalton, who seek higher resolution of size variants, more reproducible HMWPs quantitation with reduced run times and solvent cost savings. Waters expertise in SEC separations coupled with use of performance enhancing MaxPeak High Performance Surface (HPS) Technologies and innovative manufacturing processes address existing scientific challenges that include minimizing non-desired secondary ionic interactions between the biomolecules and the surfaces of the SEC column hardware.
Waters Corp XBridge BEH C8 Prep Guard Cartridge, 130Å, 5 µm, 10 mm X 10 mm, 1/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.
Waters Corp XBridge BEH Shield RP18 Prep Guard Cartridge, 130Å, 5 µm, 10 mm X 10 mm, 1/pk
XBridge BEH Shield RP18 columns complement the XBridge BEH C18 and C8 phases and provide a necessary and powerful tool for HPLC method development. The embedded carbamate group in the bonded phase ligand provides alternate selectivity, especially for phenolic compounds compared to straight chain alkyl columns.
