IDEX RefractoMax RI Detectors

The handling of our IDEX RefractoMax RI Detectors is easy given that the user can see the working conditions at a glance on the coloured display screen. Also, complex processes such as the change of eluent in the reference cell can be automated via the start-up button. Furthermore, simple instrument validation and calibration can also be carried out via the “HELP” function. A stable baseline is achieved in the shortest possible time by optimisation of the temperature control and thermal isolation. Due to its baseline stability, the RefractoMax shows a superior signal to noise ratio. Nearly no drift appears even at long analysis times. The detector is equipped with a leak sensor that switches off the pump automatically. External inlet and outlet ports, allow communication with all chromatography systems. Our IDEX RefractoMax RI is available in three flow rate options:

RefractoMax Micro:

flow rates: 0.1 – 1 mL/min

RefractoMax Analytical:

flow rates: 1 – 5 mL/min

RefractoMax Semi-Prep:

flow rates: 1 – 50 mL/min
