Although this may or may not be true wrt TSA in the US, back in 2000 we had a 4 hour (middle of night) stop-over in Zürich and I watched them wheel in this monstrous machine. While they were setting up I asked one of the (I assume) Zürich police officers if it picked up gun powder residue from shooting and the answer was no. When we went thru that checkpoint they were swabbing bags and the machine read the results. No issues.
