Static Liquid Cell

Product Features

The upper and lower chips are formed into a Liquid Cell by bonding the inner seal and epoxy resin outer seal. EDS, EELS, SAED, HRTEM, STEM and other different modes are combined in TEM. The key information such as microstructure evolution, reaction kinetics, phase transition, element valence, chemical change, microscopic stress, and atomic structure and composition evolution at the surface/interface of the sample in the liquid atmosphere can be monitored in real time and even at the atomic level.

    In situ observation ·1. Dynamic chemical reaction process, material growth process, metal solid-liquid interface corrosion process can be observed in situ under vacuum environment.
    ·2. Biological samples such as living bacteria and cells in the liquid environment can be observed and studied.
    Industry's highest resolution ·1. Original MEMS processing technology, the thickness of silicon nitride film in the chip window area can reach 10 nm.
    ·2. The thinnest interlayer between chips is only about 100~200 nm, the ultra-thin interlayer greatly reduces the interference to the electron beam, can clearly observe the atomic arrangement of the sample, and can achieve atomic resolution in the liquid phase environment.
    ·3. The specially designed shape of the chip window can avoid the thickening of the liquid layer caused by the bulge of the silicon nitride film and affect the resolution.
    High security ·1. The liquid sample size is nanoscale, which effectively ensures the safety of electron microscopy.
    ·2. The chip package adopts the bonded inner seal and epoxy resin outer seal double safety method.
    ·3. Using ultra-high temperature coating technology, the silicon nitride film in the chip window area has the advantages of high temperature resistance, low stress, pressure resistance, corrosion resistance and radiation resistance.
    Easy to operate and low cost ·1. Liquid injection and sealing are completed in two steps, simple operation and high success rate.
    ·2. Suitable for TEM holder of various brands, no need to customize sample rod, low cost of in-situ experiment.
    Team advantage ·1. The team leader participated in the development and improvement of the method at the early stage of in situ liquid phase TEM development.
    ·2. Independently designed in-situ chips, mastered the core technology of chips, and owned a number of chip patents.
    ·3. More than 20 members of the team are engaged in in-situ liquid phase TEM research, which can provide in-situ experimental technical support for multiple research directions.
