Our range of services
As GSA experts, with decades of experience and certifications, we offer you precise pollutant analyses. Whether these have been measured in indoor areas such as at the workplace, in homes or outdoors — we have the appropriate procedure and a specially trained team of experts that will provide you with the best possible support in terms of pollutant analysis.
Among other things, we use scanning electron microscopy (SEM) according to the most modern standards for the finest images, such as in the case of suspected asbestos, in order to determine substances that are hazardous to health. In the following we offer you an insight into our analysis methods according to different sample materials.
