CP-Xylenes 二甲苯分析专用毛细管柱
产品特点: Guaranteed analysis of impurities in xylene isomers Highest reproducibility due to revolutionary coating technique Temperature range 0-150º C The CP-Xylenes column offers an ideal solution to analyzing impurity levels of meta- and para-xylene isomers. Now you can analyze low-ppm m-xylene impurities in a p-xylene product, or vice versa. The CP-Xylenes column is available in two dimensions. The 0.32mm ID provides maximum separation. Alternatively, the 0.53mm ID offers reduced analysis times by operating at high flow rates. For example, the analysis of m-xylene impurities in p-xylene is possible in less than 7 minutes. These short analysis times are essential, especially in the process industry. 产品应用: 专用于二甲苯异构体中杂质分析。 应用范围:二甲苯异构体和芳香物族化合物 (碳数达C11) ASTM 方法 应用 Varian 毛细管柱 部件号 D 3760 分析异丙苯 50 m x 0.53 mm CP7428 cumene CP-Xylenes D 3797 分析邻二甲苯 50 m x 0.53 mm CP7428 o-xylene CP-Xylenes D 3798 分析对二甲苯杂质 50 m x 0.53 mm CP7428 p-xylene impurities CP-Xylenes 订货信息:CP-Xylenes Tmax-iso/Tmax-prog 120/150 ° C,TMin 0° C Part No. ID Length Df N/M 部件号 内径(mm) 长度(m) 膜厚(µ m) 柱效 CP7426 0.32 50 N/A 800 CP7428 0.53 50 N/A 500
