The RefractoMax ULTRA is a sensitive refractive index detector suitable for detecting compounds with little or no UV activity such as sugars, lipids or polymers. The instrument is designed for use in analytical HPLC with flow rates of 0.1 – 2 ml/min.
The handling of this device 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, as well as the RS-232 interface, allow communication with all chromatography systems.
Delivery includes a 2.5 µl flow cell.
