FLORISIL®是一种在前处理和色谱分析中有着广泛用途应用的高选择性吸附剂。这种吸附剂的独特之处,在于它是一种极其纯净的、硬粉末狀的硅酸镁凝胶。 FLORISIL由U.S.Silica公司制造。 Florisil®是一种用于制备和分析色谱的硅酸镁粉末硬凝胶;是在气相色谱中用作吸附剂的活性硅酸镁。 Florisil的典型化学组成:MgO-15.5%、SiO2-84%、Na2SO4-0.5% 比表面积:289 m2/g 级别信息: A 级(A Grade):标准活化等级,在650℃下活化 (适用于ISO 9337-2标准:油气指数的测定) B 级(B Grade):低活性等级,在260℃下活化 农残级(PR Grade):农药残留分析等级,在675℃活化 FLORISIL® is a highly selective adsorbent which has found extensive use in preparative and analytical chromatography.This adsorbent is unique because it is an extremely white,hard powdered magnesium-silica gel. Frequently referred to as a magnesium silicate, FLORISIL is manufactured by U.S. Silica Company. Florisil is a hard, powdered gel of magnesium-silicate used in preparative and analytical chromatography. Typical chemical composition of Florisil: MgO - 15.5%, SiO2 - 84.0%, Na2SO4 - 0.5% Surface area:289 m2/g Grade information: A Grade:Standard activation grade, activated at 650 degrees C B Grade:Less active grade, activated at 260 degrees C PR Grade:Pesticide residue analysis grade, activated at 675 degrees C Florisil 为以下机构的注册商标: U.S. Silica Company.
