{"product_id":"nextteq-tert-butyl-mercaptan-tube-no-nx156m","title":"Nextteq tert-Butyl Mercaptan Tube No. NX156M","description":"\u003cp\u003e\u003cmeta charset=\"utf-8\"\u003eThe Nextteq tert-Butyl Mercaptan Tube No. NX156M provides direct measurement of tert-butyl mercaptan over two ranges—5–80 ppm with a ½ pump stroke (50 mL) and 2.5–40 ppm with a full stroke (100 mL)—using a clear yellow-to-pink color change, with the tube calibrated on ethyl mercaptan and offering the same sensitivity for tert-butyl mercaptan, and full-stroke readings converted using a simple 0.5× formula. With a 1 ppm detectable limit at 100 mL, a 2-year shelf life, and a 32–104°F operating range, this tube is well suited for workplace and process monitoring of tert-butyl mercaptan, even though no TLV value is currently listed (TLV: N\/A), noting that hydrogen sulfide, phosphine, other mercaptans, arsine, hydrogen selenide, and hydrogen cyanide can produce similar stains and higher readings.\u003c\/p\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0606\/0425\/2412\/files\/tert-Butyl_Mercaptan_Tube_No._NX156M__Data_Sheet.pdf?v=1783343335\" target=\"_blank\" rel=\"noopener\"\u003e\u003cstrong\u003eData Sheet (PDF)\u003c\/strong\u003e\u003c\/a\u003e\u003c\/p\u003e","brand":"Sampling Depot","offers":[{"title":"Default Title","offer_id":49255919976700,"sku":null,"price":0.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0606\/0425\/2412\/files\/NX156M-Tube-box-Combo-2024.jpg?v=1771749126","url":"https:\/\/samplingdepot.com\/products\/nextteq-tert-butyl-mercaptan-tube-no-nx156m","provider":"Sampling Depot","version":"1.0","type":"link"}
