Advanced Cleaning Mechanisms

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.

Intuition, logic, and maybe even some experiences, can lead us to believe more detergent is better.  These everyday experiences where it might apply include your washing machine, dishwasher, or even your hands in the bathroom sink.  But, what is actually meant by better?  This is where concentration and detergency come into play, terms you may see in our literature and documentation, as well as our responses and solutions to cleaning challenges.
