World’s first automated foam analysis according to Ross-Miles

Chimica Oggi-Chemistry Today

KRÜSS’ Ross Miles Foam Analyzer – 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 foamability.
kruss_rmfa_diagonal_20cmMeasurements with the RMFA are distinguished by high repeatability, large sample throughput and convenient data handling. According to the standard, 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 were recorded manually with results affected by a corresponding uncertainty. With the RMFA, this belongs to the past.
The electronic height detection ensures improved repeatability and, with a resolution of 0.4 mm, achieves a previously unattainable precision. As well as the foam height, the instrument also records the height of the liquid. This provides additional information about drainage which is not obtained with a manual measurement.

As well as improved reproducibility and accuracy, electronic data measurement also saves a lot of time, as the measurement no longer has to be followed live. The user therefore gains five minutes with every foam analysis, which he can use to prepare the next surfactant solution.
