Q: I am doing a conductivity study using Alconox detergent. As I test different lots, I am seeing that the pH and Surface Tension listed on the certificate of analysis differs between lots. Do you think these variables affect conductivity enough to alter my results? A: Great question! First, let us say that when running tests on AlconoxⓇ Powdered Precision Cleaner, we … [Read more...] about Advanced Cleaning: Relationship Between Conductivity, Surface Tension and pH
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 Goniometer, Du Noüy Ring, Wilhelmy Plate and Bubble Pressure. Having one of these for measuring surface … [Read more...] about Measuring Surface Tension without Tensiometer?
