Lichrosolv® Prepsolv®液相色谱溶剂

液相色谱法已经成为研发、药物质量控制和环境分析领域的关键手段。因而对所使用的溶剂也有很高的要求。
HPLC溶剂具备低紫外吸收,低悬浮颗粒,低酸碱度和低蒸发残留的优点,经过严格的原材料选取,从开始投料生产到后期包装出厂多次进行过纯化。
LC/MS的Lichrosolv® 产品可以达成现代LC/MS离子化方法对准确检测的要求。且其包装材料也经过LC/MS质量要求的测试。
为了使分析到制备分离变得容易,Prepsolv®溶剂能够适合制备液相的要求。它们具有很低的蒸发残留(<1mg/l)和含水量,并在惰性气体下灌装。

描述
产品目录编号 106007
同义词 MeOH, Hydroxymethane, Methyl alcohol, Carbinol
概述 With their high degree of UV transmittance, low particle count, low acidity and alkalinity and low evaporation residue level, LiChrosolv® solvents are ideal for reproducible separations. Since separations are normally carried out under gradient conditions in analytical HPLC, we offer solvents in "gradient grade" as well as "isocratic grade". This enables to minimize the gradient effect of the solvent involved.
