Asbestos testing

ALS has the expertise in asbestos testing to help you make the right decisions when it comes to protecting the wellbeing of your employees and clients. Whether you need to test your house or place of business, we have the right asbestos test kit for the job.

At the ALS environmental laboratory in Cincinnati, our Microscopy department utilizes PCM, PLM, and TEM to identify fibers (primarily asbestos) in air, bulk, dust, and water samples.Our wide range of prep methods, instrumentation, and expertise, allow us to customize analyses such as fiber and particle characterization and identification to individual client needs.Air Testing CapabilitiesAt ALS, we use Phase Contrast Microscopy (PCM) with NIOSH 7400 to determine the concentration of airborne fibers >5µm long and >0.25µm in diameter having a length to width aspect ratio >3:1. This method is performed for personal samples and occupational exposures to meet OSHA requirements. The method does not distinguish between asbestos and non-asbestos fibers. Results are reported in fibers/mL (fibers/cc) based on the sample volume collected.
