The Center for Testing & Analyzing of Materials (CTAM) was founded in 1980 as the Center for Testing & Analyzing of Materials of Institute of Materials Science of Tsinghua University. The CTAM was renamed as the Center for Testing & Analyzing of Materials, School of Materials Science and Engineering, Tsinghua University in 2012.

The center currently supports more than thirty large-scale precision analytical instruments, with a particular strength in X-ray diffraction facilities, placing it in a leading position in the country compared to similar labs in terms of the number of instruments and their function, the degree of openness of access, and the development of in-house technology. For many years the center has provided an extensive range of training and open services.In addition to the X-ray diffraction equipment the center contains a range of advanced instruments, including a physical properties measurement system(PPMS), a superconductivity quantum interference device-vibrating sample magnetometer (SQUID-VSM), a vibrating sample magnetometer (VSM), an X-ray photoelectron spectrometer (XPS), an Auger electron spectrometer (AES), an electron probe micro-analyzer (EPMA), a high-temperature synchronous thermal analysis system, a thermal analysis – Infrared - MS system, an X-ray fluorescence spectrometer, a quenching & deformation dilatometer, and a nano-indenter.

The Center for Testing & Analyzing of Materialshas become an open platform for testing and analysis, providing services to researchers, scientists, and engineers both within and outside Tsinghua university, and is one of four university-level test analysis platforms. The main task of the CTAM is the testing and analysis of the structure, composition and properties of a wide range of materials.
