An overview of our laboratory services
CPP
How resistant is your stainless steel to pitting corrosion?
The electrochemical measurement of the critical pitting potential (CPP) according to ASTM G61 is an established method for determining the corrosion susceptibility of stainless steels in chloride-containing environments. The test method is based on cyclic voltammetry and determines the potential at which the protective passive layer of a metal collapses, causing localized corrosion. Standardized test methods give you comparable values worldwide, enabling you to optimize the resistance of your materials in a targeted manner.
Your benefits at a glance:
- Precise corrosion assessment
- Surface treatment comparison
- Standardized ASTM G61 testing
- Material selection support
- Realistic test conditions
CPT
How corrosion resistant is your material?
The electrochemical measurement of the critical pitting temperature (CPT) according to ASTM G150 is a proven method for assessing the corrosion resistance of stainless steels. It provides a reliable and globally comparable determination of the temperature at which stable pitting occurs under defined conditions. The measurement is particularly relevant for austenitic stainless steels and highly corrosion-resistant alloys.
Your benefits at a glance:
- Global comparability
- Best material selection
- Surface analysis
- Reliable testing
- Practical insights
Optical Microscopy
How can the quality of a stainless steel surface be reliably evaluated?
With optical microscopy! Optical microscopy is a proven method for examining stainless steel surfaces. It allows the analysis of microstructures, defects and grain boundaries to gain valuable insights into material quality, the manufacturing process and possible weak points. With the use of light microscopes, structures can be visualized down to the sub-micrometer range.
Your benefits at a glance:
- Fast & reliable
- No complex sample prep needed
- Non-destructive
- Efficient evaluation
- Suitable for metals, alloys, and coatings
Precise testing, better decisions!

RGA
How clean is your vacuum system really?
Residual gas analysis (RGA) is a highly precise method for examining gas residues in vacuum systems. It enables the quality and quantity analysis of even the smallest amounts of contamination that remain after evacuation. Especially in sensitive areas such as semiconductor or vacuum technology, control of these residues is crucial for process reliability. Mass spectrometry is used to ionize gas molecules and analyze them according to their mass-to-charge ratio.
Your benefits at a glance:
- Highly sensitive
- Fast & non-destructive
- Reduces contamination risks
- Ideal for semiconductors and vacuum tech
SEM & EDS
Why does a stainless steel component fail?
Scanning electron microscopy (SEM) with energy dispersive X-ray spectroscopy (EDS) is a powerful method for analyzing stainless steel surfaces. While SEM provides high-resolution images of the microstructure, EDS enables the precise determination of the chemical composition. This combined analysis helps to precisely identify surface defects, corrosion phenomena, material changes and contamination – a decisive advantage for demanding industrial applications.
Your benefits at a glance:
- Surface inspection
- Identifies composition and impurities
- Fast & non-destructive
- Failure analysis
- Surface treatment comparison
