Cryo-SEM analysis: Evaluation of the dispersion state of microparticles in liquid.

By rapid freezing and SEM observation, the dispersion of particles was confirmed through images! ★Data displayed at the 25th Interphex Japan★

When evaluating the particle size and structure of fine particles used in a liquid dispersion, it is common practice to dry the liquid to extract the fine particles as a powder and measure them using an electron microscope. However, this measurement method is not suitable for investigating how the particles are dispersed, as changes in the dispersion state and deformation of the particles can occur due to drying. In MST, to directly assess how fine particles are dispersed within a liquid sample, cryo-processing followed by SEM analysis (cryo-SEM analysis) is performed for evaluation.

basic information

The liquid sample is rapidly frozen by immersing it in liquid nitrogen, and FIB processing and SEM analysis are conducted within the same device while maintaining the cooling state. Detailed data will be exhibited at the 25th Interphex Japan! Our specialized technical staff will provide thorough explanations at the booth.

Price information

It varies depending on the subject of the analysis. Please feel free to contact us.
