EX1700S-HPLC Performance Comparison

The EX1700 S-HPLC® has a pressure range of 9000Psi and can handle 1.8-2.0 μm HPLC columns. It provides better separation, higher resolution, and faster analysis than conventional HPLCs. Actual analysis time can be reduced to 1/8-1/10 that of a conventional HPLC. EX1700 S-HPLC® offers superior lab solutions for fast super-efficient analysis, while greatly lowering operation costs. Whether it’s about efficiency, precision, or overall costs, EX1700 S-HPLC® has the absolute advantage over international HPLC products which run under normal pressures.
Compared with the conventional HPLC products of world-renowned brands, the EX1700 speedy HPLC offers better separation ability and peak symmetry, as well as more stable baseline and higher resolution. It also greatly reduces analysis times and costs while minimizing environmental impact. The EX1700 makes it possible to analyze hundreds of samples in just one day!
