Laboratory Cleaning: Eliminating Residual Nitrogen
If your concern is residual nitrogen interfering with analysis, we recommend Liquinox® Critical Cleaning Liquid Detergent. Liquinox is phosphate-free and is completely free-rinsing.
Ultra high vacuum compatible cleaning
Q. Can Liquinox be used to remove residues from stainless steel for ultra high vacuum compatible cleaning? A. Yes, Liquinox has been used
Residual Chlorine on Printed Circuit Boards
Q. We have found chlorine present on our printed circuit boards after ultrasonic cleaning and distilled water rinse. As ultrasonic cleaning detergent, we’re using either Liquinox or Detergent 8, but are unsure which one was used on affected boards. Could either be contributing to this issue?
A. It’s highly unlikely that either detergent, or your cleaning process, is the source of the chlorine residue. The cleaning process you described, if using detergent at recommended dilution levels, should successfully remove flux and process residues.
Detergent Color Variations
Q. The color of our Liquinox is slightly different by lot number. Why is this happening? Is there an issue, perhaps we have done something wrong with storage?
A. Do not fear! These color variations are normal. There is a range of acceptable color differences in Liquinox detergent. Differences in the age and storage conditions of the raw materials and of the Liquinox detergent itself will account for differences in color
Replacing Hazardous Acids
Q: What can I use to replace hazardous acids below pH 1 cleaning?
A: Depending on exactly what you are using your acid cleaning to do, we may be able to help you.
