Static dilution

Static dilution

The mixing of odourous gas and diluting neutral gas by volume. Often done in a form of bottle or container, it is used to store and use standards of violate organic compounds. The standards are prepared by injecting a small quantity of pure compounds into the bottle and fully evaporating them with heating. Using a gas tight syringe, a sample is then extracted from the bottle.
