Hi,
I am wondering does anyone have a good company(s) that produce autosamplers. The auto sampler should be able to grab beads out of a pipe and out of a bag in a nitrogen inerted environment. The beds are EPS and are also flammable (blowing agent).
What is the size of your beads? Where are you located? Do a search for Bristol autosamplers and Isolok autosamplers. We use them here on HC service but I do not know if they will work on your bead sampling.
