HPLC chromatography system Chromaster

UV/VISDADfluorescence

Two performance capabilities supporting data reliability: excellent reproducibility made possible by the pump and autosampler and excellent stability of the column oven and detector. [Easy-to-use] Along with simple operation and ease of use, Chromaster offers ease of maintenance, a critical requirement for HPLC. [Robustness] Hitachi's reputation for instrument robustness and reliability continues with the Chromaster, which is built using stronger materials and manufactured with Hitachi's strict quality control standards. Analysis Example from the Chromaster 60 MPa System The 60 MPa system, which can be used with columns containing 2.0 µm or smaller particles, and core-shell columns, is capable of conventional HPLC analysis and also ensures improved resolution performance and shorter analysis time. Here are two examples of experiments that can be done using the Chromaster system: Column switching valves enable automation of the pretreatment process such as biological sample enrichment, removing impurities and other processes. The ability to switch between two different wavelengths in real time can be used to resolve the co-elution of impurities in drug products.
