Request InfoPostnova Analytics GmbHPostnova Analytics GmbH has announced the PN3621 multi-angle light scattering (MALS) detector for size exclusion chromatography (SEC) and field-flow fractionation (FFF) systems. The detector simultaneously measures the intensity of scattering at 21 angles, enabling the precise calculation of the absolute molecular weight of proteins, natural and synthetic polymers, and molecular size expressed as the radius of gyration. Incorporating a broad range of working angles (7 to 164°) in a commercially available light scattering detector, the PN3621 MALS ensures unmatched precision in...See full productRelated content from Photonics MediaPRODUCTSPhotonics Spectra April 2023 IssueGas SensorA gas sensor measuring acetone level in exhaled air from Olythe SAS can aid in the diagnosis of certain pathologies such as ketosis or diabetic ketoacidosis.
