Determining When To Change Your Detonox Bath
Q: We are using Detonox detergent in our ultrasonic baths and are loving it. We use a visual inspection method (cloudiness of solution) to determine when to change the bath and are moving to conductivity and pH. It appears pH stays constant regardless of concentration?
A: As a broad statement, detergent concentration does very little to affect pH due to buffers, as well as salts, micelles, and other constituents. A pH meter wouldn’t be used to control for concentration on anything but very gross scales.
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.
Using conductivity to determine detergent concentration
Q. How is conductivity used to determine how much detergent concentrate to add to a cleaning solution to restore cleaning performance? A. Part of the technical inform
