Accomplish sensitive and reliable detection of sugars, lipids, polymers and other compounds having low absorptivity in the UV-Vis range, by using the RefractoMax Refractive Index Detectors. This detector is perfect for:
• Alcohols
• Mono- and polysaccharides
• Fatty acids
• Polymers
• Compounds with low UV-Vis activity
Designed to be both powerful and user friendly. The RefractoMax is engineered to give very high baseline stability to deliver superior signal-to-noise ratio with neglectable drift even at long analysis times. This is accomplished by the optical bench which is thermostatically controlled between 30 °C to 55 °C.
Convenient features such as a leak sensor that automatically can switch off the pump and automated start-up, facilitates everyday use and method development. The Auto Set-up function automates purging, equilibration, autozero and control of baseline stability and noise. Instrument validation and calibration can also be carried out by the push of a button and instructions on the coloured display screen. Easy integration with different chromatography systems is ensured by the ports for external input and output communication.
Because the RefractoMax is available in three different configurations there is always a model that fit your needs. The 524 Micro version is optimized for operation together with small ID HPLC columns used at low flow rates, and the 521 Analytical model is designed for highest detection sensitivity with standard HPLC column separations. The RefractoMax 522 Semi-Prep is suitable for higher flow rates and has a wider dynamic range to handle more concentrated samples.
