WebStandard samples containing the six nitrosamine impurities and four drug substances (ranitidine and sartans) were prepared from a concentrated stock solution containing 1 µg/mL of each nitrosamine impurity and ~100 µg/mL of each drug substance in 20% methanol/80% water. In chemistry and materials science, impurities are chemical substances inside a confined amount of liquid, gas, or solid, which differ from the chemical composition of the material or compound. Firstly, a pure chemical should appear thermodynamically in at least one chemical phase and can also be characterized by its one-component-phase diagram.
