In industries with high cleanliness requirements, such as aerospace, medical technology or semiconductor and automotive industries, monitoring chemical cleanliness is increasingly important. Even the smallest amounts of contaminants can lead to anything from impairment of product quality and safety to malfunction. In addition to monitoring contamination-critical process steps, Fraunhofer IPA offers problem-oriented solutions for individual and customer-specific applications with high cleanliness requirements.
While in many applications a defined level of contamination on components and surfaces is desirable (e.g. in corrosion protection), in conventional process steps such as bonding, coating and welding, even the smallest contaminations can have serious consequences for the functionality or downstream processes. Continuous monitoring of the chemical cleanliness status is therefore an important part of quality control.
Whether organic and inorganic contaminations on technical surfaces, time-dependent haze effects on optics, outgassing and long-term storage effects of materials or contact transfer – we support and provide advice on the cause analysis and evaluation of chemical cleanliness on components and surfaces of any kind.
We can offer a wide range of methods and equipment for individual applications:
With the increasing cleanliness requirements, the monitoring of the process environment in contamination-critical areas is also constantly increasing. Depending on the process, predefined limit values must not be exceeded in order to meet product-specific cleanliness requirements. Often, for example, solvent-based adhesives, coatings, materials or flooring systems unknowingly introduce chemical contaminants into process environments. In many industries, these unwanted components in the air can lead to defective products, production downtime or even damage to health.
Fraunhofer IPA provides a variety of methods for the reliable monitoring of a chemically clean process environment:
The determination of chemical contamination – whether airborne or condensed on surfaces – by liquid extraction is becoming increasingly important. When transferring the contaminants into ultra-clean liquids, geometric factors (small/large surface area, internal or structurally difficult-to-access locations) often play a major role and require component-specific extraction methods.
Depending on the type of contamination, the following methods can be used:
By law, medical technology companies are liable for their products. They are obliged to minimize the risks for patients if their products are used as intended. Fraunhofer IPA offers a wide range of services on this subject.

The analysis of contaminations – whether on surfaces, in the air or in liquids – is now possible with a variety of methods and devices. With increasing cleanliness requirements in the industries, the demand to meet them is also rising. Often, test methods and systems need to be adapted or newly developed to suit the specific product application. Many companies are faced with the question of what is necessary to achieve the required product quality.
Fraunhofer IPA provides a wide range of suitable methods and laboratory analytical procedures for detecting a wide variety of contaminations.
We gladly support you in the development and optimization of your individual and component-adapted test method. Optionally, the test method can be integrated into an (existing) system.
We perform standardized analyses according to national and international standards. The illustration shows an extract of the applied standards in the field of analysis of liquids, gas phases and materials. Further standards are also applicable and can additionally be implemented on a customer-specific basis.
