Location: Room 110 of Science and Technology Building

Person-in-charge: Li Xiao

Tel.: 62332598-6110

Main functions:

Can be used to observe and detect surface appearance characteristics and composition, and conduct specimen test analysis at micron and nanometer levels. Its most important feature is its ultra-high resolution scanning image observation capability, especially the use of the latest digital image processing technology, to provide high magnification and high resolution scanning images. It is the most effective instrument for particle size measurement and morphology observation of nanomaterials, and is also an indispensable tool to study the relationship between material structure and performance. It is widely used in biology, medicine, metal materials, polymer materials, chemical raw materials, geological minerals, commodity inspection, production quality control, gem identification, archaeology and antique authentication, as well as physical evidence analysis in forensic criminal investigation.
