LaChromUltra High-Speed Liquid Chromatograph

LaChromUltra delivers ultra-fast analysis, higher resolution, increased sensitivity and the flexibility to run both higher pressure and conventional HPLC analyses on a single system.




LaChromUltra delivers ultra-fast, high-resolution analyses through a balanced optimization of a 2μm particle column and a maximum 60MPa system pressure.


  • Ultra-fast analysis times: Reduced to about 1/10, as compared with our conventional HPLC.
  • Accurate and complete data: detector response times (0.01sec) and sampling periods (10msec) designed for high speed analysis.
  • Easy to use: finger-tight column switching system allows you to easily change between ultra and conventional LC columns.
  • Flexible: Choose Hitachi's 3 or 5μm particle columns for easy method transfer between ultra and conventional LC applications on one system.


Analysis time is reduced to 1/10
