{"product_id":"2940013595200","title":"Sulfur Hexafluoride as a Mine Ventilation Research Tool - Recent Field Applications","description":"Sulfur hexafluoride (SF6) is an odorless, colorless, nontoxic gas that has found acceptance as a tracer gas in research on ventilation patterns, measurement of air leak rates, respirable dust reductions due to bagging hood modifications, and the study of airflows relating to gob boreholes. Following a short review of the SF6 sampling technique, this report describes recent Bureau of Mines projects in which SF6 was used successfully as a tracer gas, enabling researchers to acquire representative data quickly and inexpensively.","brand":"1001 Property Solutions LLC","offers":[{"title":"Default Title","offer_id":47082988601584,"sku":"2940013595200","price":1.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0737\/7593\/9824\/files\/2940013595200_p0.jpg?v=1763583250","url":"https:\/\/shop-qa.barnesandnoble.com\/products\/2940013595200","provider":"Barnes \u0026 Noble (DEV)","version":"1.0","type":"link"}
