About This Product

Lab System's original differential refractive index detector boasts industry-leading separation maintenance performance.

■Features

・A new method is used to suppress peak dispersion in general preparative separation and recycling preparative separation. - Optical zero adjustment can be easily performed from the front panel. -Uses a high-intensity LED lamp as the light source, eliminating baseline drift due to lamp heat generation. - Temperature control is applied to the optical system, allowing for fast and stable measurements. (RI-2000AP/P: approx. 30 minutes, RI-2000A: approx. 120 minutes from temperature control ON) ・The RI-2000AP has flow paths for analysis and preparative separation, so one unit can be used for both analysis and preparative separation without replacing the flow cell. -Easily switch between analysis and preparative flow paths and perform reference purge operations. ・In case of a liquid leak, a ``liquid leak detection (alarm) unit'' (optional) can be installed to prevent the accident from spreading. ・We can also manufacture "inert specification machines" that do not use any metal in the wetted parts. (Special order product)

■The biggest feature of the RI-2000 series is safe valve flow switching.

・It is possible to maintain separation of drainage liquid. The detected data and the components of the waste liquid are almost the same. ・Safe and unbreakable as almost no high pressure is generated during switching. Detection data is also stable. By making special improvements to our valves, we have solved the problem of high pressure generation and are now able to collect safe and stable data while maintaining drainage fluid separation. Reliable quality control

■Traceability system

All of the differential refractive index detectors in the laboratory system are tested by skilled technicians in accordance with the procedures recommended by the Japan Analytical Instruments Association standard "Method for expressing the performance of high-performance liquid chromatographs" (JAIMAS 0005-1984). Calibration is performed using equipment that has been regularly certified by a measuring instrument manufacturer or certified calibration company. This allows us to say that we have traceability to national standards.

■Traceability system chart and calibration certificate can also be issued.

The laboratory system's differential refractive index detector undergoes rigorous standard testing, but we are also able to issue traceability system diagrams and calibration certificates so that it can be used in fields that require extremely high precision, such as pharmaceuticals and foods. It has become.
