Ifegwu, C. Anyakora, in Advances in Clinical Chemistry, 2016. 11 SolidPhase Extraction. Solidphase extraction (SPE), due to its versatility and ease of use, has largely replaced liquid–liquid extraction protocols [14–20,73].Using octadecyl SPE, urine 1hydroxypyrene (3– μmol/mol creatinine) could be reproducibly determined in occupationally exposed workers [7].
Reducing the Risk of Fumed Silica Dust Exposure. Fumed silica is a manmade substance, so it''s no surprise that it''s known by multiple names—Diatomaceous earth, Diatomaceous silica, Diatomite, Silicon dioxide (amorphous) and Vitreous silica, at least. In fact, before 1989, its official name was silica (amorphous). Today, however, industry and regulators tend to call the substance fumed ...
