Electric field asymmetric flow field current meter

POSTNOVA company launched a new intelligent precision shunt field current analyzer EAF2000 in 2017. It is based on the asymmetric flow field current separator, adding an electric field current EF3 component and replacing it with an EAF4 separation channel box.

1、 Product Introduction

　　Intelligent precision shunt field current meterIt is to apply two separation forces simultaneously in the same separation channel, one is the vertical downward flow force generated by the cross flow pump, and the other is the separation force of the upward or downward current generated by the voltage applied to the separation channel. The purpose is to unlock the adsorption between molecules and nanoparticles, or to unlock the adsorption force between sample molecules or particles and the filter membrane on the bottom wall of the separation channel, so that the sample can be gently separated in a uniform and unaffected environment, ensuring the accuracy of molecular weight distribution data and nanoscale distribution data, and also accelerating the separation speed appropriately.

Currently, the EAF2000 modelIntelligent precision shunt field current meterAt present, it is the only commercialized two-dimensional field current analyzer product in the world. Other field current separator manufacturers either do not have current dynamic field/electric field current, or the electric field current cannot be combined with AF4, so they cannot reach the technical level of simultaneously applying two separation forces. The application of two-dimensional field flow greatly improves the separation ability of protein samples and nanomaterial samples, and the data is also more accurate.

2、 Product Comparison

Like other field current analyzer products, EAF4 can also be directly combined with various qualitative and quantitative detectors online, such as MALS, IV, DLS, RI, UV, FL, ICP-MS/OES, and so on. Intelligent precision diversion, large volume injection, and online concentration are the * technologies on AF4/EAF4.
