What Are the Key Components of Chemical Composition Standards?
Chemical composition standards encompass several critical components: 1. Purity: The degree to which a nanomaterial is free from contaminants. 2. Elemental Composition: The specific elements present in the nanomaterial. 3. Molecular Structure: The arrangement of atoms within the nanomaterial. 4. Particle Size Distribution: The range and average size of nanoparticles in a sample. 5. Surface Chemistry: The chemical functionalities present on the surface of nanoparticles.
