Ultra-High Performance Liquid Chromatograph

    ChromasterUltra Rs

                ChromasterUltra Rs, an ultra-high performance liquid chromatograph, provides the ultimate in high performance, high resolution, and high sensitivity analysis that are becoming requirements for research and development in pharmaceutical and chemical fields.


High Sensitivity

                    A total-reflection capillary flow cell is incorporated into the diode array detector to answer to the increasing need for high-sensitivity analysis of hazardous substances, genotoxic impurities, etc. A high-sensitivity flow cell with an optical path length of 65 mm is also available. In addition to the capability of high-sensitivity analysis, carryover is reduced through the use of a double-corkscrew mixer.

Stable solvent delivery allows a board range of analyses from UHPLC to HPLC

                      Stable solvent delivery is achieved, independent of pressure and solvent composition, by incorporating LBT control and correcting the bulk modulus of the solvent. Stable analyses are supported with 5-µm, 3-µm, and 1.9-µm columns.

Excellent reproducibility

Even for gradient analysis

                       Under high-pressure conditions, highly reproducible high-resolution results are achieved.

High-resolution analysis of related substances (impurities)

                       Erythromycin (a macrolide antibiotic having a basic structure comprised of a 14-membered ring) is used as a sample model for separation of the main component and related substances to compare the separation using an HPLC column vs. the separation using a UHPLC column.


                        All modules can be controlled from the Graphical User Interface (GUI) controller.
The GUI is comprised of a color LCD monitor (5.7-inch color TFT display with LED back-light) and a touch panel made for easy viewing and simple operation.
Up to 10 programs including a timer function, pre-analysis tasks (Wakeup), and post-analysis tasks (Sleep) can be created for a system.
The GUI controller enables you to check the status of consumables usage for all units that are connected to the system.
