Native IEX-MS analysis of monoclonal antibodies using YMC Accura BioPro IEX SF columns
23 May 2025Whilst direct coupling of ion exchange chromatography (IEX) to mass spectrometry (MS) simplifies workflows and minimizes artefacts, the high salt concentrations typically used in IEX pose a challenge for MS compatibility.
Explore data from Roche Diagnostics that shows how using a 2.1 mm ID bioinert coated YMC Accura BioPro IEX SF column delivers superior resolution compared to a standard 4.6 mm ID PEEK column when coupled to MS. See how even from the first injection, sharper peaks, higher resolution, and optimal recovery are all delivered.

Ion ChromatographyIon chromatography, also known as ion exchange chromatography, is a high-performance liquid chromatographic technique used for the separation and identification of ions or polar molecules in a sample, including proteins, nucleotides and amino acids. Equipment includes ion exchange columns, ion exclusion columns, ion chromatography systems, pumps, and detectors. Find the best ion chromatography equipment in our peer-reviewed product directory: compare products, check customer reviews and receive pricing direct from manufacturers.Mass SpectrometryMass spectrometry (MS) is a powerful analytical technique used to identify and quantify molecules based on the mass-to-charge ratio of gas-phase ions. It provides detailed information about the structure, composition, and properties of compounds and is widely used across fields such as environmental monitoring, materials science, drug discovery and development, food and beverage testing, and wider chemical research. Key MS techniques include tandem mass spectrometry (MS/MS), liquid chromatography–mass spectrometry (LS-MS) and inductively coupled plasma (ICP-MS). Choosing from these wide range of techniques and technologies can be a daunting task, so keep up to date with scientific applications, performance expectations, and customer reviews here all in one place.

AntibodiesAntibodies are used in techniques such as confocal and fluorescence microscopy, flow cytometry, ELISA, ELISPOT, immunohistochemistry, western blotting and immunopreciptation. Select specific antigen reactivity, high specific affinity, low non-specific binding, monoclonal or polyclonal, primary or secondary antibodies and associated conjugates such as an enzyme or dye for visualization.Monoclonal AntibodiesMonoclonal antibodies (mAbs) are lab-made molecules that can bind to specific antigens on cells, making them highly effective in treating cancers, autoimmune diseases, and infections. These targeted therapies are transforming the treatment landscape for many conditions. Browse our peer-reviewed product directory to find monoclonal antibodies for research and clinical applications; compare products, check reviews, and get pricing directly from manufacturers.BiopharmaceuticalsBiopharmaceuticals are proteins and other compounds (such as nucleic acids) produced by living organisms that have uses as therapeutics or for in vivo diagnostics. The most well known example of a biopharmaceutical product, and the first to be approved for therapeutic use, was recombinant human insulin.BioprocessingBioprocessing is the use of biological systems for the conversion of raw materials to desired products. This includes the research, development and manufacturing stages of production and can refer to food processing, small-molecule pharmaceutical manufacture, production of recombinant protein therapeutics, or the generation of renewable energy.
