离心是许多样品制备工作流程中至关重要的一步。分析离心用于有效沉淀表面、废水或污泥等样品中的沉淀物。它还用于液/液萃取(LLE,DLLME)后的两相分离,或变性后的蛋白质沉淀。离心作用极大地简化了很多样品制备的应用。
PAL离心机结构紧凑,不占用工作台空间,也完全集成到了方便的PAL Method Composer软件可快速创建自动化工作流程脚本。
空气制冷的PAL离心机经过唯一认证,可用于操作易燃液体,如经常使用的有机化合物溶剂、酒精或醚类,装在带帽的小瓶中。
PAL离心机可以有效地集成在许多工作流程中。省略了繁琐且容易出错的离线步骤。可提供2mL、10mL、20mL的转子或与高达5000g的相对离心力(RCF)组合的转子
将当前离心机的转速(每分钟转数)转换为重力值(g force)。没有半径信息的离心机规格(rpm)是没有意义的,也无法进行比较。对于已知的离心机,从以厘米为单位的半径和以转/分为单位的速度,g force的转换是用以下公式计算的:
g force (RCF) = 1.118. 10-5. r .rpm2
RCF:相对离心力,以g的倍数表示
r:从中心到小瓶底部的转子半径[cm]
rpm:转速,单位为每分钟转数[min-1
Automated determination of glyphosate, AMPA and glufosinate in food by online ligand exchange SPE-LC-MS/MS
The presented method allows a time-efficient sensitive detection and quantification of glyphosate, AMPA and glufosinate in
complex food matrices by applying online SPE.
Automated Sample Preparation for Therapeutic Drug Monitoring by LC-MS
Automated sample preparation reduces the costs per sample and avoids sample handling errors. This is especially important in therapeutic drug monitoring or diagnostics based on blood samples.
