A universal guard column.It can filter the insoluble solid particles in mobile phase and sample, prevent column from being polluted and prolong the life of column.

Disposable needle filter is a fast, convenient and reliable filter commonly used in the laboratory. With beautiful appearance, light weight and high cleanliness ,it mainly used for sample pre-filtration and particulate matter removal. It is the first choice for filtering small samples of IC, HPLC and GC. Each batch of needle filters were tested by ion chromatography. Testing the 1...

In the process of analysis, the impurity interference, organic matter or metal ions in the sample will pollute the packings of column, reduce the separation ability and service life of the column, and the impurity ions will interfere with the separation of ions. So the sample pretreatment column should be used. It can effectively remove the organic matter and impurity...

High-pressure and low-pulse dual-piston tandem advection pump is made of peek material, which can achieve stable flow control without damper. It can realize the combinatorial analysis mode of isocratic, binary, quaternary gradient and micro-analysis,and automatic piston rod cleaning and maintenance-free function, which is suitable for trace analysis in scientific research and special industries.

High-pressure and low-pulse dual-piston tandem advection pump is made of stainless steel, which can achieve stable flow control without damper. The product adopts 32-bit embedded microprocessor with ARM7 core, electronic pressure fluctuation suppression technology, and  high-precision DC servo motor, to realize the combinatorial analysis mode of isocratic, binary, quaternary gradient and micro-analysis, which is suitable for trace analysis in...

The capture column can continuously remove the ionic contaminants in the eluent, thus achieving low drift during gradient operation.  

The eluent cartridge is the replacement consumable of the eluent generator. The eluent is replaced with the electrode to prevent leakage. It is connected by aeronautical connector and peek connector, which is convenient for disassembly and assembly.  

VF-02 Electromagnetic six-way injection valve is an electrically driven automatic injection valve. It uses stepping motor to control position switching of valve. It has compact structure and superior performance. Both automatic and manual can be used independently and can be used as automatic sampling valves in chromatographic industry or as flow path switching valves. The space occupancy is small...

VI-11 manual six-way injection valve is a universal injection valve, which is widely used in IC and LC. Cutting valve continuous flow design is adopted to avoid the impact of instantaneous pressure on the system. With excellent performance and long life, it can ensure continuous injection of 30,000 times. Product Parameters Model Valve Switching   Mode Maximum   Pressure Outer Diameter   of Tube Rotor...
