Software for HPLC method development, ChromSwordAuto® 5 and ChromSwordAuto® 5 Hitachi Edition

Supplier: COLLECTION PREFIX HPLC

ChromSwordAuto® 5: Communicates directly with the HPLC instrument in order to create a fully automated HPLC or UHPLC method development station. The unique ChromSwordAuto® software is capable of developing and optimising HPLC methods fully automatically within just a few hours. Methods already in use can also be optimised, thus reducing analysis time considerably. All you have to do is place the sample in the autosampler, set a few parameters and start the optimisation process. ChromSwordAuto® then predicts the method conditions and controls the HPLC system connected in recording the chromatograms. These are analysed by the software and the optimal conditions determined. The rapid optimisation mode can be used to provide an overview of the performance of the column/solvent system selected or to rapidly screen columns and eluents considered for use. The fine optimisation mode additionally collects and evaluates further ancillary data and produces up to 10 sets of alternative optimal HPLC conditions. Both of these operating modes can be applied in combination with column and solving switching procedures in order to try a variety of column/solvent combinations or to establish optimal pH conditions – fully automatically.
