Some samples contain layers of different materials (look on the picture above as an example). In the next answer you need to tell us how you want your sample to be tested.
- By default, we analyze all layers of a sample together without separating them. This is the least expensive option. Disadvantage of this technique is that if we detect asbestos in the sample, you would not know from which layer it comes.
- If you want the lab to analyze several layers of a sample separately, please list the individual layers as subsamples: a), b), c).... When we see on your request: 1a. Gypsum, 1b. Grey plaster; 1c. White skim plaster, then we understand that the sample of drywall should be separated and analyzed layer by layer. Each layer will be analyzed and invoiced separately
