Found this after a bunch of clicking. I know someone is else talked about using this exact method and it really seems super easy especially now that I have a PID. One thing I'm curious about though, does anyone happen to know if their is a cartridge for my 3m half mast respirator that will work on the antimony fumes ? Yes I know I'm a wuss for wearing one but I kinda like my lungs and it seems to be cheap insurance lol
