默克薄层层析产品简介

在高效液相色谱技术发达的今天,薄层层析色谱依然为广大化学分析家提供者成本低廉,快速高效的分离检测手段。

根据不同填料特征,默克薄层层析板分为四大类:常规薄层层析板TLC、高效薄层层西板HPTLC、整体化薄层层西板UTLC、制备薄层层西板PLC

 

默克薄层层析产品标的含义

F—— 含有荧光指示剂

F254+366——荧光指示剂的激发波长

F254S——蓝色荧光指示剂(对酸稳定)

G——粘合剂含硫酸钙

H——不含粘合剂

P——制备薄层层析

R——经特殊工艺进行深度纯化

W——可备水浸润

Aluminium oxide 60 F 254 neutral-氧化铝薄层层析板
描述
产品目录编号 105550
Replaces 5550-7; 5550
概述 Aluminiumoxide plates are used to analyze basic and neutral compounds at different pH levels. Depending on the pH range in question, professionals can choose between two kinds of aluminum oxide plates. Under aqueous conditions, basic aluminum oxide plates are best for separating basic compounds, while neutral plates are ideal for separating neutral compounds. Available with or without a fluorescence indicator, our TLC aluminum plates handle a wide variety of applications thanks to neutral and basic aluminum oxides with 60 Å and 150 Å pore sizes.
