FullyAutomated Quantitative Capillary Electrophoresis (qCE)

    A quantitative capillary electrophoresis was developed by utilizing a rotary type of nano-volume injector, auto-sampler and a thermostat with cooling capacity. The nano-injector with an accurate internal loop provides a new solution for the problem of accurate quantitativein CE.  The accuracy and precision were greatly improved compared with conventional CE.

  Features

1.  Using the nano-injector with 4 nL or 10 nL internal loop

2.   Greatly improved accuracy and precision compared with conventional CE

3.   Stable, repeatable and reliable results are ensured by a thermostat with cooling capacity

4.   No cross contamination and discrimination effects

5.   Continuous on-line analysis

6.   Ready to couple with μUV, μLIF, μECD, μELSD, μMS

   Introduction of core models         

          1. Auto sampler

           All of the modules of the quantitative CE system are automatically controlled by a computer program.

          2. Nano-injector

           (1) The injector volume accuracy was guaranteed by the carefully designed nano-injector with an accurate internal loop.

           (2) Applies to all type of sample and have no discrimination effects.

           (3) Continuous on-line analysis can beperformed and have no need to interrupt the process of electrical balance.

           (4) Have no cross-contamination between the samples and the buffers

           (5) Valve injection is simple, conventional and safe.

          3. Electrical decoupler

           (1) Allowed electrical current to flow between the buffer and capillary but without permeating the buffer and sample to pass through 

                 the membrane on the capillary

           (2) Realizing the technology of powering on capillary

           (3) Isolating the injector from the electrical field

           4. Thermostat

            Temperature control medium: liquid

            Tempertature range: 4-40 ℃

     Control& data processing software

          Set instrument unit control, data acquisition and processing in one and fully compatible with GLP norms
