MIC Analysis (Microbiologically Influenced Corrosion / Biocorrosion)

With our MIC analysis (Microbiologically Influenced Corrosion), different micro-organisms and bio-functions involved in the biocorrosion process are detected and quantified, giving you insight into problems or possible risks in your system. On request we can furthermore give you advice on prevention, monitoring and control of MIC for your specific situation.

Analysis essentials

  • To determine if micro-organisms causing biocorrosion are present around your metal damage;
  • To monitor your system for the presence and numbers of micro-organisms as part of a monitoring procedure;
  • To test whether the measures you have taken are effective in preventing micro-organisms causing biocorrosion.

Content of the package

We offer different MIC packages. We do this so you can decide which package is most suitable for you wishes and budget. Of course, it's always possible to establish custom-made packages or specific analyses. Please contact us for more information.

Background information

Corrosion is an electrochemical process leading to the deterioration of materials that can be caused or accelerated by microbiological activity. This process is called biocorrosion or Microbiologically Influenced Corrosion (MIC). Biocorrosion causes localized corrosion problems in unexpected places. Furthermore, the process is faster than normal (10 - 100 times). It has been detected in a variety of sectors, including the petrochemical industry and in industrial water systems. Estimates are that 30 to 50 percent of all corrosion cases are influenced by micro-organisms. Diagnosing and monitoring the risks for biocorrosion are therefore important to prevent damage.

Micro-organisms can influence the corrosion process in different ways. The first one is depolarisation, where the end products of corrosion are removed by the activity of micro-organisms. This causes an imbalance and therefore an increase of the corrosion process. The second way micro-organisms influence the corrosion process is by creating a biofilm (biofouling). Due to the biofilm specific local conditions are created, that favor micro-organisms causing biocorrosion. The third way is the production of corrosive metabolites, for instance acids that affect the material. Finally micro-organism can degrade biocides or coatings by using these compounds: micro-organisms can use components as nutrient and therefore induce biocorrosion.
