Thermal field flow separatorIt is an efficient separation and analysis instrument based on field flow separation technology, widely used in materials science, chemistry, biomedical and other fields.

　　Thermal field flow separatorBy applying a vertical temperature gradient within the separation channel (with a temperature difference of up to 100 ℃ between the upper and lower walls), separation is achieved using the principle of molecular thermal diffusion (Brownian motion). The separation process does not require a fixed phase, and molecules form concentration gradients due to differences in diffusion coefficients under the action of a thermal field. Combined with the thickness of the laminar layer and the distance from the channel wall, differentiated elution of different substances is achieved. This technology breaks through the limitation of traditional gel chromatography (SEC/GPC) that only separates by molecular size. It can separate by molecular size and chemical properties at the same time, and is especially suitable for the analysis of blends.

Application fields:

1. Material science: It is applicable to the separation and analysis of polymers and high molecular materials in weak polar organic solvents and medium polar organic solvent systems such as DMF/DMAC/DMSO. It can analyze the molecular weight and molecular weight distribution of polymers in rubber, separate gel substances and test their content, and can also be used to study the thermal properties and physicochemical properties of materials.

2. Chemical analysis: It can be used to separate and analyze substances with different particle sizes and molecular weights in liquid samples, especially suitable for the separation of macromolecules, colloids, particles, polymers, and nanomaterials. It can help researchers gain a deeper understanding of the structure and properties of substances.

3. Biomedical research: It has important applications in the fields of pharmaceuticals and biotechnology, and can be used to separate and analyze biomolecules such as proteins and nucleic acids in biological samples, which is helpful for drug development and disease diagnosis.
