WebA great starting point would be to use volatile mobile phases. A list of mobile phases suitable for API and LCMS are summarized in Table 3. In addition to the fundamental mobile phases such as water, methanol and acetonitrile, acetic acid is also commonly used to adjust the pH level. For buffer solutions, volatile salts such as ammonium acetate ... In chemistry, volatility is a material quality which describes how readily a substance vaporizes. At a given temperature and pressure, a substance with high volatility is more likely to exist as a vapour, while a substance with low volatility is more likely to be a liquid or solid. Volatility can also describe the tendency of a … See more Volatility itself has no defined numerical value, but it is often described using vapor pressures or boiling points (for liquids). High vapor pressures indicate a high volatility, while high boiling points indicate low volatility.
