RI Detectors RefractoFlow 2030 - for GPC/SEC

preparative Differential Refractometer


   Versatile RI Detector

   For use in GPC/SEC and for dn/dc determination.
   Stand-alone or integrated into GPC/SEC multidetector-systems.


For GPC / SEC applications, the differential refractometer is the most widely used detector. The RefractoFlow 2013 demonstrates highest baseline stability via symmetrical construction without multiple reflection on null glass and beam splitter. This has a positive impact on the wander, pulsation and drift parameters.

The detector can be switched to preparative operation without intervention in the instrument or changing of cells.
An optimum signal/noise ratio ensures high sensitivity. The standard wavelength is 620 nm; other wavelengths from
980 nm to 460 nm can be selected. The reference cell is filled and rinsed automatically. A connection for fraction collector is available.

Absolute determination of the concentration is possible with this refractometer.

The devices of the serie "Bioline" are extensively metal-free.
