ICH-Q3D has been in effect since June 2016 for new marketing authorization applications and has applied to previously authorized medicinal products since December 2017. The latest ICH Q3D and USP<232> chapters include catalyst elements, and other inorganic contaminants that may enter a drug product.

database.ich.orgaddition, for elements with high PDEs, other limits may have to be considered from a pharmaceutical quality perspective and other guidelines should be consulted (e.g., ICH Q3A). This guideline presents a process to assess and control elemental impurities in the drug product using the principles of risk management as described in ICH Q9. This ...

Temperature Dependence of Semiconductor Conductivity
www.iiserkol.ac.incharged impurities. As a result, as the temperature decreases, impurity scattering increases, and the mobility decreases. This is just the opposite of the effect of lattice scattering. The total mobility then is the sum of the lattice-scattering mobility and the impurity-scattering mobility.
