Lichrosolv® Prepsolv®液相色谱溶剂

高效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技术。因而对所使用的溶剂也有极高的要求。
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，从最初投料生产到最后包装出厂多次进行过纯化。
用于LC/MS的Lichrosolv® hypergrade产品可以满足所有现代LC/MS离子化方法对精确检测的要求。且其包装材料也经过LC/MS质量要求的专门测试。
为了使分析到制备分离变得容易，Prepsolv®溶剂能够适合制备高效液相的要求。它们具有极低的蒸发残留（<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.
