Abstract
There are described methods and apparatus for assessing foams generated from liquids. Existing methods are slow and labor intensive. The new methods involve generating foams from liquids and optically obtaining information to enable parameters relating to the generated foam to be measured. Although single samples of liquids may be processed the methods are particularly suited to processing multiple samples to obtain data relating to foams at a high rate. The apparatus includes automated handling equipment to enable samples to be moved between workstations and relative to associated optical equipment that is used to obtain information relating to the foams.
