Advanced Cleaning: Relationship Between Conductivity, Surface Tension and pH

Q: I am doing a conductivity study using Alconox detergent. I am seeing that the pH and Surface Tension listed on the COA differs between lots. Do you think these variables affect conductivity enough to alter my results?

A: Here’s the short answer… Surface tension does not have any interactive relationship with conductivity; pH has a very small, essentially negligible interaction with conductivity; and concentration and temperature are much bigger causes of change in conductivity.

Measuring Surface Tension without Tensiometer?

Q. Is there any way to “eyeball” surface tension to see if it’s dropping when roughly measuring concentration or bath life?  
A. To numerically measure surface tension, you need a tensiometer and this is the recommended method. Tensiometers come in many varieties including…
