P230 High Pressure Pump (Analytical)
Features
 

The P230 Pump is a dual plunger solvent delivery system. The mechanical design includes short plunger stroke technology with two check valves. This results in very low pulsation. The microprocessor controlled speed regulation leads to a very stable speed of  the step motor, driving the plungers. Integrated calculation software continuously corrects flow rates according to the system pressure. Provide flow rate adjustment function when the actual flow rate is different from the preset. The RS232 remote port is designed to control by data system.

DAD Data Working Station

To guarantee DAD system a stable operation under Windows 9x, we adopt virtual driver. With a friendly interface and strong function DAD data-processing platform, users can conveniently observe and process contour map, spectrogram, chromatogram and three-dimensional spectrogram-chromatogram. With sufficient functions of chromatographic data processing and quantitative calculating, arbitrary revolving and parts magnifying, users can obtain more vivid visual effect and results analysis.

DAD workstation can provide all kinds of chromatograms, including single wavelength, arbitrary two-wavelength absorptance, wavelength time procedure, max absorption wavelength and total absorption, and among them, the most sensitive detection method is max absorption wavelength chromatogram, while the best method to quantitate reproducibility is total absorption chromatogram.

DAD system provides many discrimination methods on peaks purity, including contour map, three-dimensional spectrogram-chromatogram, overlap spectrogram, wavelength comparison diagram and peaks purity calculating method.

Users can conveniently built their ultraviolet spectrogram gallery with the multifunctional spectrogram gallery managing and searching procedure, and the programme can auto-pick spectrogram to each peak from spectrogram, chromatogram and three dimensional data; auto-search spectrogram gallery; users can also add the auto-picked spectrogram into appointed gallery.
