  • Peptides

    Chromatographic modes for peptide separation include reversed-phase, ion-exchange, hydrophilic-interaction, and size-exclusion chromatography and are used for applications ranging from the analysis and purification of synthetic peptides,  to the characterization of complex proteolytic digests, and bioanalysis. These methods rely on taking advantage of chemical and physical differences between peptides species.

  • Reversed Phase

    Reversed-phase chromatography using ion-pairing reagent such as TFA and formic acid can deliver highly resolved separations of complex peptide mixtures whose sequences may differ by a single amino acid. In general, the hydrophobicity of the peptide determines the elution order, with the least hydrophobic peptides eluting first.

  • HPLC and UPLC Columns

    Reversed-phase chromatography using ion-pairing reagent such as TFA and formic acid can deliver highly resolved separations of complex peptide mixtures whose sequences may differ by a single amino acid.

  • Reversed Phase


    Reversed-phase chromatography of proteins, done with columns consisting of wide-pore  size particles ( e.g, 300Å) functionalized with short-ligand length chemistries,  is a separation technique based on the relative hydrophobic characteristics of the proteins in solution. Gradients of increasing of organic solvent concentration are frequently used to affect separations in the presence of ion-pairing reagents that minimize undesired ionic interactions.

  • HIC

    Hydrophobic Interaction Chromatography (HIC)  is characterized by the adsorption of compounds to a weakly hydrophobic surface at high salt concentrations, followed by elution with a decreasing salt gradient.  This technique is well suited for protein separations due its non-denaturing characteristic.

  • Ion Exchange

    Ion-exchange chromatography is a powerful technique with its ability to resolve different protein species, based on their surface charge. Separations are based on the use of either salt, pH, or salt/pH gradients.

  • Size Exclusion

  • Standards and Kits

    Specially formulated, synthetic oligonucleotide standard designed for verification of HPLC/UPLC instrument and column performance for analysis of oligonucleotide applications.

  • Amino Acids

Matrix effects and accurate quantitations are some of the challenges that are adressed by pre-column derivatization and high resolution chromatographic separations.

  • Reversed Phase

    The gradient separation of precolumn derivitizated amino acids by ion-pair, reversed-phase LC is based on the different hydrophobic characteristics of each labeled constituent.

  • Standards and Kits

    Waters amino acid kits and reagents are designed for accurate and reproducible quantitation of amino acids from various sample matrices using either UPLC or HPLC methods.
