Asymmetric flow field flowmeter

The asymmetric electrokinetic field flow separator uses a hollow, flat separation channel without fixed phase to replace the traditional gel permeation chromatographic column. At the same time, a separation force is applied in the direction perpendicular to the sample flow to realize the separation of samples.

1、 AF2000 typeAsymmetric current dynamic fieldProduct Introduction of Flow Separators

The AF2000 multi detector asymmetric flow field flow separation instrument produced by POSTNOVA Analytical Instrument Company in Germany is a complete set of field flow separation instruments, which includes: liquid phase single pump, online deaerator, column temperature box, automatic sampler AS, automatic fraction collector FC, differential refractive index detector RI, static multi angle laser scattering detector MALS, four capillary intrinsic viscosity detector IV, all of which are produced by POSTNOVA company itself and do not require the use of liquid chromatography hardware equipment from other HPLC/GPC manufacturers. Therefore, it has good system integrity and compatibility. The entire set of equipment uses a software platform interface (including automatic sampler, automatic fraction collector), and is composed of... POSTNOVA company and its authorized agents are responsible for all after-sales service work, without the need for other HPLC manufacturers to provide after-sales service support. In addition, POSTNOVA also OEM produces UV detectors and UV fluorescence detectors FR from Shimadzu Corporation in Japan, ELSD evaporative light scattering detectors from Agilent, and acts as an agent for the sales of Malvern's offline/online dual-purpose dynamic laser particle size analyzer/detector in the UK. Moreover, these detectors also use the same software platform, NovaFFF, together with the AF2000 asymmetric flow field field flow separator AF4. The AF2000 multi detector AF4 can also be directly integrated with products from major ICP-MS manufacturers online, and the software can also be nested and shared on the NovaFFF software platform. The AF2000 asymmetric flow field current separator can also be easily upgraded to a two-dimensional field current flow EAF4, thereby further improving the effectiveness of water phase applications such as proteomics and nanomaterial science.

2、 Product advantages

AF2000 typeAsymmetric current dynamic fieldThe flow separator is equipped with advanced technologies such as FOCUS automatic sample aggregation, S3 intelligent precision diversion and online concentration, and low pulsation dual syringe cross flow pump, which are fully applicable to various samples from polymer materials to nanomaterials and even to biomacromolecule materials. The PN4020 column temperature box used not only has semiconductor cooling and heating capabilities, but also can upgrade the electronic control automatic switching valve group to achieve automatic switching between the AF4/EAF4 separation channel box and the SEC/GPC column, making it convenient for users to compare different separation methods.
