Technical Cleanliness Verification
Verification of ionic contamination using ion chromatography
During the verification of ionic contamination, we use ion chromatography (IC). This process detects dissolved salts using a conductivity measuring cell and determines the nature and quantity of the dissolved salts. IC is superior to the ROSE test because it provides greater resolution of detail.
Fast, reliable
measurement results
- Assessment of the ionic contamination (anions, cations and organic acids) present on the assembly
- Qualitative and quantitative resolution of substances using high-performance liquid chromatography (HPLC)
- Assessment of unknown substances based on the retention time
- Continuous quality monitoring and surface qualification using IC
- Analysis in accordance with standards such as IPC-TM-650 2.3.28 or customer-specific requirements
Ion chromatography
Using ion chromatography (IC), cations and anions are assessed with the aid of standards. In this way unknown substances can also be identified via their retention time.
Normally we analyse for you during the investigation of ionic contamination:
- Anions (bromide, chloride, fluoride, nitrate, nitrite, phosphate, sulphate)
- Cations (ammonium, calcium, lithium, magnesium, potassium, sodium)
- Organic acids (acetate, adipate, glutamate, malate, methane sulphonate, succinate, phthalate)
Please contact us for special analyses.
Accredited test laboratory for the analysis of ionic contamination
Identification and quantification of organic and inorganic substances, materials, residues, deposits and contaminants using FT-lR and energy dispersive (EDX) spectroscopy are accredited by Deutsche Akkreditierungsstelle GmbH (DAkkS) in accordance with DIN EN ISO/IEC 17025. Furthermore, all our other specialist areas have also been accredited.

Frequently asked questions
How does ionic contamination occur?
Ionic contamination can have many causes. Often insufficient rinsing, e.g. after the electroplating of a component or flux residues after soldering are responsible. However, incorrect handling of the related component or simply dust can cause contamination.
What are the possible consequences of ionic contamination?
Ionic contamination can cause, among other issues, the formation of dendrites that, in turn, can cause short circuits that destroy the entire component or cause even more damage. However, even if the damage is not so serious, ionic contamination, for instance caused by electrochemical migration, can lead to malfunctions. For this reason the measurement of ionic contamination is an important element of quality assurance.
