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 MALDI-TOF MS Workflows for Streamlined Bacterial Identification
This application note demonstrates the successful automation of two sample preparation workflows, Formic Acid (FA) and Beads method, for bacterial identification using Matrix-Assisted Laser Desorption/Ionization Time-of-Flight Mass Spectrometry (MALDI-TOF MS).
A single-sample workflow for joint metabolomic and proteomic analysis ofclinical specimens
Integrating proteomic and metabolomic data enhances ourunderstanding of biological processes and diseasemechanisms. Traditional multi-omics workflows often requireseparate sample processing, leading to increased variability.To address this, we developed MTBE-SP3, an optimizedsingle-sample workflow that combines a 75% EtOH/MTBEmetabolite extraction with automated single-pot solid-phase-enhanced sample preparation for proteins.
ASMS 2025 - From Sample to Species - Automated MALDI-TOF MS Workflows for Streamlined Bacterial Identification
Rapid and accurate bacterial identification is crucial in fields such as clinical diagnostics and food safety, yet traditional methods are often slow. MALDI-TOF MS offers apowerful alternative, but sample preparation is a bottleneck. We propose an automated workflow using a robotic platform to streamline this process. This automated MALDI-TOF MS workflow enhances bacterial identification by reducing manual steps and improvingstandardization across applications.
Automated Sample Preperation for LC/MS and GC/MS - Solutions for Food and Environmental Analysis
In this presentation we want to discuss an important development and a demand from analytical laboratories about the standardization and the automation of sample preparation procedures for food safety, environmental, the forensic or pharmaceutical analysis.
