The launch of the Viscotek SEC-MALS 20 brings new standards of performance and greater choice in gel permeation/size exclusion chromatography (GPC/SEC) and extends theMalvern Analytical光散射探测器家族，用于测量蛋白质，大分子和聚合物的绝对分子量。
Malvern Panalytical的Viscotek系列现在包括具有成本效益的选项，对于每种类型的光散射检测 - 低角度，直角和多角度的性能无与伦比 - 允许Malvern Paralytical以最合适的技术来应对每个GPC/SEC挑战。随着其检测器范围的扩展，Malvern Allytical将成为唯一提供所有光散射选项的供应商。
Molecular weight has an overriding influence on the physical, structural and chemical properties of polymer, protein and macromolecular species. Modern GPC/SEC systems use static light scattering (SLS) detectors for absolute molecular weight, rather than relying on unsuitable, potentially inaccurate external calibration methods. Malvern Panalytical’s new Viscotek SEC-MALS 20 is designed to measure absolute molecular weight for a range of macromolecular applications and to supply superior radius of gyration (Rg) measurements for molecules larger than 10-15 nm.
新的Viscotek Sec-Mals 20具有比任何其他市售MALS系统的探测器更多。这种提高的检测水平，尤其是在较低角度，为分子量和大小的外推提供了最佳数据。因此，即使在高分子量下，精度也有显着提高。
The incorporation of a vertical flow cell with radial optics, rather than the more conventional lateral flow cell, means increased sensitivity and accuracy for low angle detection. It also allows the use of a variety of different mobile phases without the need to alter the optical properties of the detector.
The Viscotek SEC-MALS 20 detector runs with Malvern Panalytical’s established OmniSEC software. It is compatible with any commercially available SEC instrument and is available both as a standalone unit or integrated within Malvern Panalytical’s multi-detector Viscotek GPC/SEC systems.
多角度光散射（MALS）探测器广泛用于生物药物研究中。在某些情况下，这是因为它们提供了用于衡量回旋半径的最准确数据，而在其他情况下，它们已经成为公认的行业标准。随着Viscotek Sec-Mals 20的推出，Malvern Panalytical扩大了其探测器范围，为客户提供了最广泛，无偏见的光散射系统的选择。
