Cleanliness Testing Services

Choose the cleanliness test methodology that is best for your process and materials with free guidance from a KYZEN cleaning expert.
  • The R.O.S.E. test method, the industry standard production line test for measuring the cleanliness of electronic assemblies for more than forty years, remains the current standard for conducting daily production tests for electronic assemblies.
  • Ion chromatography (IC) is an analytical chemistry method that separates chemicals with an electrical charge, called ions. There are two main types of ions: cations and anions. Cations have a positive charge and anions have a negative charge. Chromatography is the process of separating chemicals from each other based on some property, in this case electrical charge. These ions are detected by measuring the conductivity of the solution passing through the detector, similar to the older ROSE testing but much more sensitive. It can reveal the actual contaminates instead of just detecting there is one. It is important to note that not all molecules can be detected using IC. They must be able to conduct electricity in a solution. IC is the only commonly used method to identify and quantify ions. This ability better allows our customers to understand the potential impacts on the reliability of their parts, and allows for quantitative measures of the impact different conditions have on their process. It can also be used to show the efficacy and value added by cleaning in a quantitative way.
  • Millipore Testing – KYZEN’s Analytical Laboratories will perform gravimetric or Millipore testing on industrial sample parts during process development to gauge the effectiveness of the washing. This method looks for the particulates that remain on the part after cleaning. A solvent wash collects the particulates that are then filtered and weighed. The particles that collect on the filter paper are then analyzed microscopically to understand their size and composition.
