Du nuoy ring method
WebThe force is measured on a ring shortly before a liquid film tears using a torsion meter. The surface tension is calculated from the diameter of the ring and the tear-off force. … WebBoth signals were analyzed by a computer for recording and processing. The sodium dodecyl sulfate (SDS) and iso-amyl alcohol were used for this research . The lowest concentration this device could detect DST changes was 45 mg/1 for SDS and 0.020% for iso-amyl alcohol.
