Liquid chromatograph

The stable flow rate ensures the repeatability of qualitative and quantitative indicators of liquid chromatography.

Excellent wavelength repeatability ensures the consistency of energy and the quantitative index of liquid chromatography.

The adoption of filter group (6 pieces) structure reduces the influence of stray light on the analysis results, and improves the minimum detection concentration and linear range of the instrument.

Powerful and completely anti control workstation software.
