Every scientist goal is to analyze target compounds, quickly and reliably within a given time and budget. The ChroZen UHPLC System satisfies both productivity and efficiency by producing the results 4-10 times faster than conventional HPLC’s while ensuring both superior sensitivity and resolution.

The Chozen UPLC System is designed to withstand real ultra-high pressure up to 18,800 psi (1,300 bar). The powerful pump technology provides an accurate and precise flow rate by applying the concept of linear drive technology into two pairs of serially coupled pump heads, this results in the end-user being able to fully utilize the UHPLC columns and have reliable data.

Benefits

Higher Productivity
  • 4-10 times faster than traditional HPLC

Greater Efficiency

  • Low flow rates injection minimizing solvent and sample usage

Remarkable Resolution & Sensitivity

  • Total Reflection Cell with Liquid Core Waveguide Technology enhancing resolution
  • Reduced system dead volume giving improved sensitivity

Reliability
  • Automatic compressibility compensation providing accurate control for more stable gradients

Maximize UHPLC Columns
  • Ultra-high pressure, up to 18,800 psi, utilizes the lifetime of UHPLC column

Resolution & Sensitivity

One of the primary concepts of UHPLC for enhanced resolution, is to enable the use of UHPLC columns packed with small particle size (sub-2μm).

To support this, the ChroZen UHPLC mechanically minimizes
system dispersion by utilizing a low internal volume with a Total Reflection Cell and applying the Liquid Core Waveguide technology which all reduces the loss of light source to maintain the intensity in optical clarity. Also, the extremely fast data acquisition rate of 125 Hz, enables rapid data processing for an enhanced effect on peak heights and width. Therefore, it produces a higher resolution and sensitivity.
