ELSD 6000 evaporative light scattering detector Introduction: The Omnitor Evaporative Light Scattering Detector, as a universal mass detector, can detect any sample with lower volatility than the mobile phase without the need for chromophores. ELSD is more sensitive than differential refraction detector, insensitive to temperature changes, and stable baseline. It has been widely used in the detection of components of traditional Chinese medicine and traditional Chinese patent medicines and simple preparations, fatty acids, carbohydrates, amino acids, drugs, polymers, etc., especially for the analysis and detection of other UV non absorption or weak absorption chemical components. The conventional UV detector detection of ELSD in different HPLC methods is influenced by the functional groups or optical properties of the compounds. The unique detection principle of ELSD determines its universality, and its performance is significantly better than that of UV detectors in the analysis of non chromophore samples. The Omnitor evaporative light scattering detector has passed CE certification, and mainstream brands of liquid chromatography can use its liquid chromatography system software to control the ELSD6000 evaporative light scattering detector, achieving efficient and accurate detection of UV non absorbing substances. Features: 1. Compact structure: Adopting a brand new optical path design, the volume is compact (26 cm * 19 cm * 46 cm), which can be stacked with liquid chromatography systems for use 2. Excellent detection performance: quantitative repeatability reaches RSD6 ≤ 1.5%, baseline noise is as low as 0.01 mV, drift is small, and precision is high 3. Rapid cooling: helps to quickly switch between different detection methods 4. Nozzle heating: helps improve atomization effect, especially when detecting oily samples 5. Linear gain adjustment: Linear gain adjustment helps users finely adjust the height of the output chromatographic peak 6. Atomization tube adjustment: The atomization angle can be freely adjusted to meet the detection needs of different samples 7. System automatic detection: 16 instruments perform daily self checks, with multiple safety designs to prevent mobile phases from entering the detection room, reduce instrument maintenance, and extend service life 8. Method management: Up to 10 groups (each with 25 parameters) of structured menus are managed to simplify user operations 9. Monitoring and alarm: Real time monitoring of temperature, pressure, and flow rate, and sound and light alarms for abnormal situations 10. Control acquisition software: dedicated multi platform control software, Clarity ® Dynamic link library, platform supports integration with any HPLC chromatography system 11. Multiple communication modes: RS-232, RS-485, USB, LAN (TCP/HTTP), programmable external event interface 12.
