Surface Tension vs Interfacial Tension. Both surface tension and interfacial tension are effects based on liquids. Both these effects take place due to the unbalanced intermolecular forces between the liquid or solutions molecules.
Statistical process control (SPC) is a method of quality control which employs statistical methods to monitor and control a process. This helps ensure the process operates efficiently, producing more specification-conforming product with less waste (rework or scrap).
A: Quality Control is the statistical measurement of the laboratoryâs ability to meet analytical specifications for precision and accuracy. These specifications may be pre-determined by method requirements, or developed within the laboratory as a function to monitor trends and deviations from norms.
