Monolith Reversed-Phase Columns for High-Resolution Protein Separations at High Flow Rates ProSwift® reversed-phase monolith columns uniquely provide the advantages of high resolution at exceptionally high flow rates for protein separations. They deliver the outstanding resolving power of nonporous analytical media combined with faster separations than any bead based columns available. ProSwift polymer monolith columns achieve long column lifetime, exhibit reproducibility even after hundreds of runs, and have broad pH stability, providing high stringent wash capability.ProSwift polymer monolith media are uniquely suited for the separation of proteins. Each monolith is a single cylindrical polymer rod containing an uninterrupted, interconnected network of flow-through channels of a specific pore size. These large channels and the monolith’s nonporous surfaces result in fast mass transfer for high-resolution and fast protein separations. The channels also produce low backpressure, allowing the use of higher linear velocities with minimal loss of resolution.ProSwift® RP Protein Column Features: High resolution at high speed Highest operational flow rates available High throughput and improved productivity Optimal performance in a broad range of applications Excellent stability over a wide pH range of 1 to 14 Outstanding reproducibility and ruggedness High stringent wash compatible, for example, 1 M NaOH High loading capacity Column Details: Chemistry: Phenyl Length: 50, 250 mm ID: 1.0, 4.6 mm

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. Visit our product directory to receive quotes direct from the manufacturer. 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.ProteomicsProteomics is the systemic bioinformatics study of proteins and amino acids, including their structure, size, function and identification. Tools used in proteomics include chromatography, blotting and gels, protein arrays, mass spectrometry and ELISA and associated analysis software. Analyzers and proteomic systems should be sensitive, high resolution, fast and may be automated for high-throughput.ImmunoassayImmunoassays are laboratory tests that utilize antibody-antigen interactions to detect specific substances. They are widely used in diagnostics for detecting diseases, drug testing, and environmental monitoring. These assays offer rapid, sensitive, and precise detection of biomarkers, making them invaluable in clinical and research labs.
