The LU3100 quaternary low-pressure gradient mixer is a new high-performance liquid chromatography quaternary low-pressure gradient mixer designed and developed by Dalian Elite Analytical Instrument Co., Ltd. based on the LU1201/230II quaternary low-pressure gradient mixer, with independent intellectual property rights. As an accessory of high-performance liquid chromatography, when combined with a high-pressure constant flow pump, a single pump liquid chromatography system (isocratic system) can be upgraded to a quaternary low-pressure gradient system, providing different ratios of mobile phase for conventional applications and method development applications.

Adopting an imported four element proportional distribution valve, it has the advantages of short opening time, consistent response of each channel, and precise proportional distribution;

Adopting two modes of time positioning and cam positioning to meet the accuracy of proportional allocation under different flow rates;

The quaternary channel can be switched freely to meet the diversified needs of liquid chromatography mobile phase and avoid multiple changes of mobile phase;

● Real time display of flow settings and flow path operation status, facilitating real-time observation of instrument working status.
