Dynamic Foam Analyzer

Analyzing liquid content and drainage of foam

The LCM Liquid Content Module for the DFA100 measures the moisture of foams with respect to time on different foam height levels. The results are obtained by detecting the foam's conductivity as a proven method. They provide you with knowledge about a foam’s stability and help you optimize products where moisture plays a key role, such as washing foams.

Applications

• Foams for washing and cleaning

• Foams in food and personal care products

• Surfactant development

• Firefighting foams

• Flotation as a method for separating solids

Measuring methods

• Foamability and foam stability using the optically detected height of foam created reproducibly
• Foam formation behavior of heavily foaming liquids using stirring cycles
• Optically detected foam bubble sizes and their statistical distribution
• Moisture and drainage behavior of foam using its electrical conductivity
• Carrying out a measurement up to 20 consecutive times and displaying the results together

Measuring results

• Maximum liquid content after foam formation

• Time for reduction of liquid content to 75%, 50%, and 25% of initial value

• Drainage curve

• Each result at up to seven height levels in parallel

• Additional results for foam height and volume from DFA100 main instrument
