Chromnav Chromatograohy Data System is a powerful modular software. It is designed for various kinds of chromatography applications. The applications range from fast analysis using UHPLC and SFC, to routine analytical separations, to control of preparing chromatography using intelligent fractionation. It has built-in error free ethernet protocol server, instrument control and data acquisition. It provides 24/7 fault free operation. JASCO’s proprietary LC-Net II protocol provides the highest data reliability even for high acquisition rates used by UHPLC PDA detectors. The ChromNAV user interface is a modern design which is easy to use as it has almost similar look and feel as any other common programs that run in operating systems such as Windows XP and Windows 7. Because of this feature and its various other interfaces, learning everything from instrument set-up, to sequence control, to data analysis and advanced reporting becomes quick.
