Viscometric Detector

Triple detector MDS390(B)

MDS390 Triple detector

The MDS390 Multi Detector Suite brings advanced GPC/SEC with light scattering, refractive index and viscometry detection  to your laboratory. The instrument can come with up to three detectors at once or can be field upgraded any time a new technique is required.


Any combination of any MDS detectors is possible. Each MDS detector can be individually heated from 30 – 60 °C to ensure baseline stability. All detectors can be used in series, ensuring all of the analyte is studied.

The MDS390 can be integrated into any GPC/SEC or FFF system.
