Refractive Index Detector Shodex RI-101 analytical
Analytical version up to flow rate 5 ml/min.
- Description
- Parameters
Differential Refractive Index Detectors are used for detecting little or no UV active samples such as sugars or polymers. The Shodex RI-101, employs a number of improvements for shortening the time for stabilization. By using a micro-processor it is capable of automatic start-up from eluent replacement to checking the base-line stabilization. The detector is fitted with external input and output terminals as well as RS232C communication ports, permitting advanced automation by linking the detector with various HPLC systems, enabling advanced automation by combining the detector with various chromatographs.Differential Refractive Index Detectors are used for detecting little or no UV active samples such as sugars or polymers.
