Asbestos Testing and Analysis
Due to the widespread use of asbestos in a wide range of products, particularly in construction materials, asbestos is one of the most frequently encountered hazardous substances in existing buildings. This mainly applies to buildings constructed in the post-war period up to the final ban on the manufacture and use of asbestos and asbestos-containing materials in 1993 (cf. Chemicals Prohibition Ordinance). However, asbestos-containing products may also be found in much older buildings, for example as a result of later renovation work.
In addition to classic asbestos products such as asbestos cement, floor coverings, fire protection panels, sprayed asbestos, or sealing and packing materials, gaskets and sealing cords, an increasing number of asbestos-containing products have been identified over time due to advances in analytical methods. Many of these cannot be detected with the naked eye without appropriate laboratory analysis. This particularly applies to surface-applied materials such as tile adhesives, plasters, or fillers.
As a result, renovation, refurbishment, and maintenance work, as well as demolition of existing buildings, always carries a potential risk due to improper handling of asbestos-containing materials. Even smaller interventions in private settings may lead to fibre release and associated risks for workers and third parties. Furthermore, the presence of asbestos is relevant for the assessment and valuation of real estate, as necessary remediation measures may significantly reduce property value.
In addition to all legal and economic considerations, the
protection of human health and hazard prevention are always our top priorities. In our
modern, DIN EN ISO 17025-accredited
scanning electron microscopy (SEM) laboratory, we offer you the opportunity
to analyze samples for asbestos and other fibrous hazardous substances.
Identification of asbestos in materials
Scanning electron microscopy provides a reliable and rapid method for identifying asbestos in material samples. We offer fast and reliable testing of suspected materials for the presence of asbestos. Analyses are carried out by our experienced laboratory team in accordance with current guidelines, e.g. VDI Guideline 3866, Part 5. Depending on the nature of the sample and the specific requirements, detection limits can be adjusted to meet individual needs.
The analytical methods used also allow the identification of other inorganic fibres, such as synthetic mineral fibres (MMF). Based on the composition of the identified fibres, we can determine the carcinogenicity index (KI) of synthetic mineral fibres upon request.
In addition to qualitative asbestos detection, we also offer quantitative determination of asbestos fibre mass content in materials such as powders and dusts in accordance with IFA Working Manual, Method 7487.
We are happy to offer our clients the option to submit sample material. Please use our order form for material samples. Please ensure that samples are securely packaged for shipping. Personal delivery of sample material is also possible during business hours; outside of these hours, samples can be deposited in our sample drop box. If required, our qualified field staff are also available for on-site assessments and safe sampling.
Indoor air investigations
In addition to the analysis of material samples, we also offer testing of air samples for asbestos and other fibrous dusts, such as synthetic mineral fibres (MMF). Air sampling is carried out by our qualified field staff.
Our measurement services include:
- Status quo measurements (to determine the level of exposure to inorganic fibrous particles; baseline assessment)
- Monitoring measurements as part of interim measures
- Clearance measurements for the removal of protective measures
- Measurements to assess the success of remediation measures in accordance with the Asbestos Directive (success monitoring)
- Control measurements to protect third parties from fibre release during remediation work
- Stationary and personal workplace measurements
We also offer evaluation of pre-loaded filters. Air sample analysis is carried out in accordance with applicable guidelines (e.g. VDI Guideline 3492, DGUV Information 213-546).
By operating two scanning electron microscopes in parallel, we achieve a high degree of flexibility in scheduling, which is particularly important during ongoing asbestos remediation projects (e.g. clearance or control measurements).
Special investigations
For specific requirements, we are happy to provide our expertise and work with you to determine the appropriate analytical method, for example:
- Determination of asbestos in drinking water
- Characterization of unknown materials using SEM/EDX analysis
- Analysis of splinter-like hazardous substances and blasting media
- Investigation of corrosion processes
- Microscopic material comparisons
- and much more
