World’s first automated foam analysis according to ross-miles

Chimica Oggi-Chemistry Today


KRÜSS GmbH has exhibited its new foam analysis instrument, the Ross Miles Foam Analyzer – RMFA, at Analytica 2016 in Munich. The RMFA is the world’s first instrument for measuring foam height electronically according to the ASTM D 1173 standard, which is commonly referred to for investigating the foamability of foam-forming substances. Measurements with the RMFA are distinguished by high repeatability, large sample throughput and convenient data handling. For measurements carried out in accordance with ASTM D 1173, the foam-forming solution is presented in a high, cylindrical receiver vessel with standard dimensions. A second quantity of the same solution is introduced from above by means of a likewise standardized reservoir. This passes through the column and forms foam as a result of the turbulence on mixing with the receiving phase. The foam height is measured as soon as the reservoir is empty and also after 60, 180 and 300 seconds. Up to now, the height and time have had to be recorded manually. Results were therefore dependent on the user and were subject to a corresponding uncertainty. With the RMFA, this is belongs to the past.
