chemical composition standards

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.
