HPLC for Herbal Industry & R&D Laboratory (Fully Automated Preparative Chromatography System)

Features:
1. Equipped with an automatic sampler and fully enclosed sample bottles, it can achieve fully automatic overnight operation;
2. The injector has a needle washing function, which can greatly avoid cross contamination;
3. Adopting a powerful fraction collector with quick valve switching for collection;
4. The software supports intelligent fraction collection, with multiple collection methods such as time, threshold, peak, and manual;
5. The software supports fraction indexing function, which displays the real-time collection position of fractions and the corresponding chromatographic peak position;
6. The instrument uses high-precision HPLC to prepare chromatographic pumps with good reproducibility;
7. The instrument uses high-pressure gradient mixing without the need for a deaerator, and the gradient has almost no hysteresis;
8. Adopting a deuterium tungsten lamp combination light source and a four wavelength UV-VIS detector, it can detect any four wavelength signals within the range of 190nm-850nm;
9. Equipped with a self checking function for the light source, it manages the lifespan of the light source and reminds timely replacement;
10. Equipped with a monochromator self calibration function;
11. Adopting a 1200 line high-resolution grating, it has good spectral efficiency in the ultraviolet visible range;
12. Adopting an X-Y matrix collection method, the number of collected samples is much higher than that of multi way valves;
13. The software has the functions of automatic injection, gradient, chromatogram, fraction collection chart, and equipment status display;
14. The software has automatic injection status display and control functions, which can display the status of valves, injection pumps, and injection arms;
15. The software has the function of online UV-VIS spectral scanning, which can obtain the UV spectra of components;
16. The software supports gradient program setting function, with step, linear, and point drag gradient curves;
17. The software supports functions such as chromatographic peak separation and quantification, audit tracking, data management, user management, and personal management;
