The Viscotek SEC-MALS 20 multi-angle light scattering detector measures absolute molecular weight and size (Rg) of proteins and polymers. Its 20 detector array and vertical flow cell ensure exceptional accuracy.
The Viscotek SEC-MALS 20 brings new standards of performance and greater choice in gel permeation/size exclusion chromatography (GPC/SEC) and. Malvern’s Viscotek range now includes cost-effective, high-performance options for every type of light scattering detection – low angle, right angle and multi angle – allowing Malvern to answer every GPC/SEC challenge with the most appropriate technology. With this extension to its detectors range, Malvern becomes the only vendor to offer all light scattering options.
The Viscotek SEC-MALS 20 has more detectors than any other commercially available MALS system for GPC/SEC. This increased level of detection, particularly at lower angles, gives the best possible data fit for extrapolating molecular weight and size, with gains in accuracy, even at high molecular weights. A vertical flow cell with radial optics gives increased sensitivity and accuracy for low angle detection. Different mobile phases can be used without altering the detector’s optical properties.
The Viscotek SEC-MALS 20 detector is compatible with any commercially available SEC instrument, is available as a standalone unit or integrated into Viscotek GPC/SEC systems and runs with OmniSEC software.

Analyzing Vitamin K1 Levels in Vegetables Eaten by Warfarin Patients Using HPLC UV–vis
April 9th 2025Research conducted by the Universitas Padjadjaran (Sumedang, Indonesia) focused on the measurement of vitamin K1 in various vegetables (specifically lettuce, cabbage, napa cabbage, and spinach) that were ingested by patients using warfarin. High performance liquid chromatography (HPLC) equipped with an ultraviolet detector set at 245 nm was used as the analytical technique.
