Postnova PN3700 Zetasizer Nano DLS Detector

Please contact us for pricing & details. Online orders will not be accepted.

The advanced detector hardware allows operation in Online Mode connected to FFF with a special flow cell for continuous DLS and also in Offline Mode using standard cuvette cells as standalone detector for batch DLS measurements. The system allows input of up to two additional external FFF detectors (e.g. RI, UV, FLD, etc.) and automated operation when used together with the PN9020 Interface Box for remote start capability. The Zetasizer Nano is connected as the last detector inline. Switch between flow and batch mode measurements is achieved by simply changing the cuvette within seconds. The system will automatically identify eluted FFF peaks without any calibration, expressed as size or molecular mass. Software allows overlay of RI, UV and FLD traces with Rh data and also static light scattering intensity signal. Using the Zetasizer Nano there is no need to rely on size or molecular weight calibration standards for FFF anymore.

High Sensitivity Online Dynamic Light Scattering Detector, special customized for use connected to Field-Flow Fractionation (AF2000, CF2000 and TF2000).
