Analytical HPLC/UHPLC and ULDC Systems

The most flexible HPLC platform

Let your application define your system solution.

In HPLC, components of a mixture are carried through the stationary phase by the flow of a mobile phase and separation is based on differences in migration rates among the sample components. Therefore, the nature of your analytes defines not only the method but also the HPLC system.


Main characteristics of the analytes:
Molecular weight defines the pore size of the stationary phase. Solubility defines the HPLC mode, chemistry of stationary phase and eluent. Concentration and matrix defines the detection parameters and column dimensions.

The solubility of your analytes defines the HPLC mode. The elutropic series defines the solvent strength for the most often used chromatography modes normal phase and reversed phase. 


  • Isocratic binary high pressure gradient (HPG) or quaternary low pressure gradient (LPG) pump Pump heads allowing flow rates up to 10 ml/min 
  • at 862 bar or 1 240 bar up to 2 ml/min
  • Autosampler with 0.1 μl sample aspiration at max. 1 240 bar with zero sample loss
  • Choice of highly sensitive UVD, MWD, DAD, or RID detectors with intelligent temperature control
  • Wide range of flow cells available, including remote cells
  • Finger-tight high pressure stainless steel capillary connections “K-Connect”
  • Extensive safety features such as leak management and sensors
