The materials can be analyzed by Alfa Chemistry include:
Techniques for material testing
Optical Microscope
The optical microscope is a commonly used material analysis equipment that can observe the microscopic structure of materials through the principle of optical magnification. Through the optical microscope, the crystal structure, grain size, and grain boundary distribution of materials can be observed, thereby understanding the organization and properties of the materials. In addition, the optical microscope can also be used to observe the surface morphology and defects of materials, and evaluate the surface quality of materials.
Scanning Electron Microscope
The scanning electron microscope is a high-resolution material analysis equipment that can obtain information about the surface morphology and microstructure of materials by using the signals generated by the interaction between the electron beam and the materials. The scanning electron microscope has a very high resolution and can observe structural features at the nanometer scale or even smaller.
X-Ray Diffractometer
The X-ray diffractometer is a device used to analyze the crystal structure of materials. It can determine the crystal structure and interplanar spacing of materials by irradiating the materials and measuring the diffraction angles. The X-ray diffractometer can help researchers understand the crystal structure, lattice constants, and crystal plane orientation of materials, and perform analysis and research on the physical and chemical properties of materials.
Thermal Analyzer
The thermal analyzer is a device used to study the thermal properties of materials. It can analyze the thermal response of materials at different temperatures to understand the thermal stability, thermal conductivity, and thermal expansion characteristics of materials.
Mass Spectrometer
The mass spectrometer is a device used to analyze the composition and structure of materials. It can measure and analyze the mass-to-charge ratio of various components in the material, and thereby determine the chemical composition and molecular structure of the material. The mass spectrometer has important applications in material analysis, chemical analysis, and biomedical fields, and can help researchers and engineers understand the composition and properties of materials.

Advanced Characterization Techniques for Nanostructured Materials
Jagadeesh, P., Rangappa, S. M., & Siengchin, S. (2024). Advanced Industrial and Engineering Polymer Research, 7(1), 122-143.
The recent advances in nanostructured materials have been widely applied in many fields, particularly in the biomedical field. Bioactivity, biocompatibility, toxicity, and nano-bio interface properties are some of the major concerns in biomedical applications. Therefore, characterization techniques are needed to investigate the nanostructured materials for biomedical applications.
Techniques such as field emission scanning electron microscopy (FESEM), dynamic light scattering (DLS), scanning probe microscopy (SPM), near-field scanning optical microscopy (NSOM), and confocal microscopy can be used to analyze the topological studies (spatial relationships, geometrical features) of nanostructures. The internal structure studies can be performed using techniques like X-ray diffraction (XRD), transmission electron microscopy (TEM), and magnetic resonance force microscopy (MRFM). Additionally, compositional analysis can be carried out using techniques such as X-ray photoelectron spectroscopy (XPS), energy-dispersive X-ray spectroscopy (EDS), Auger electron spectroscopy (AES), secondary ion mass spectrometry (SIMS), and X-ray photoelectron spectroscopy (XPS).
Characterization of Nanoporous Materials
Thommes, M., & Schlumberger, C. (2021). Annual Review of Chemical and Biomolecular Engineering, 12(1), 137-162.
Detailed analysis of the textural properties (e.g., pore size and connectivity) of nanoporous materials is crucial to determining the relationship between these characteristics and the performance in gas storage, separation, and catalytic processes. Advances in the development of nanoporous materials with uniform, customizable pore structures, including the introduction of hierarchical pore systems, have provided tremendous potential for these applications.
Textural characterization can be based on different techniques, such as gas adsorption, X-ray diffraction, small-angle X-ray and neutron scattering, mercury porosimetry, electron microscopy, and nuclear magnetic resonance (NMR) methods.
Quantitative Analysis of Asbestos-Containing Materials
Yang, K., Yoo, K. C., & Jung, J. (2020). Minerals, 10(6), 568.
Asbestos is an industrial term that covers six mineral types: chrysotile, crocidolite, amosite, asbestiform tremolite, asbestiform actinolite, and asbestiform anthophyllite. Compared to man-made materials, asbestos has several advantages, such as mechanical strength, heat resistance, chemical resistance, durability, and sound-absorbing properties. Asbestiform talc is not very important industrially. Asbestos and elongated mineral particles can lead to asbestosis, pleural abnormalities, bronchial cancer, and mesothelioma. Therefore, the use of asbestos-containing materials (ACMs) for fire protection, insulation, construction, and friction has been banned in 52 countries, including the United States and the European Union.
The advantages of X-ray powder diffraction (XRPD) analysis lie in its non-destructive nature, reliability, rapid and simple sample preparation, and low cost. XRPD analysis has been used for mineral identification and quantitative/qualitative determination of various types of fiber minerals in asbestos-containing materials (ACMs).
