When analyzing multiple samples with dynamic light scattering (DLS) technique, chemists often pipette or pour the suspension into a cell, press the ‘Go’ button, and get a perfect answer within a few ...

As a surface-sensitive technique, the diffraction signal comes from the top few nanometers of the crystal lattice in EBSD. Hence, the top layer needs to be devoid of oxidation, contamination and ...

Analytical chemistry has witnessed substantial progress in enhancing both sample preparation and detection methods. Modern techniques strive for high sensitivity, improved selectivity and streamlined ...
