@sara mentioned a $35 test at a Harvard lab and an XRF or X-ray Fluorescence test - what kinds of tests are available to detect or measure H2S and how much do they cost? hydrogen-sulfide lab answered lab-testing lab-tests question:hydrogen-sulfide ### 1 Comments Could someone double check on xrf for h2s? Xrf works on electrons closest to the nucleus. It could detect sulfur, but not h2s unless paired with something else. Is this a question? Click here to post it to the Questions page.
