Crystalline samples (single crystals of substances such as organic compounds, metal complexes, biological macromolecules, etc.) with a size preferably above 0.05 mm. The crystal surface should be clean, with consistent color and transparency. It should be free of attached small crystals, and free from defects such as cracks, overlaps, or imperfections.

Precise determination of the three-dimensional structure and electron density map of single crystals such as organic compounds, metal complexes, and biological macromolecules (proteins, nucleic acids, peptides, carbohydrates, etc.). This enables the acquisition of microscopic information regarding bond lengths, bond angles, torsion angles, molecular configurations, and conformations, and facilitates the study of their patterns, thereby further elucidating material properties and structure-function relationships.
