网络研讨会: Preparation and analysis of environmental samples With a focus on the new Substitute Building Materials Ordinance

在环境分析领域，样品制备与分析面临严苛要求，因为土壤、污泥、沉积物或动物饲料等样本中的污染物浓度通常较低。为获得准确可靠的分析结果，必须进行精细的样品制备与分析。新版《替代建筑材料条例》也为实验室带来了新的挑战。

在三场网络研讨会中，Retsch、CEM和岛津三家公司将全面展示可靠高效的样品制备与分析方案。研讨会重点涵盖实验室样品的可重复均质化处理、新型萃取技术、消解方法以及气相色谱质谱联用（GCMS）、液相色谱质谱联用（LCMS/MS）和电感耦合等离子体质谱（ICP-MS）等分析技术。

Tips and tricks for comminuting and homogenising samples for environmental analysis

In the first part of the webinar series, Retsch presents the importance of sample preparation for the subsequent analysis and shows ways to eliminate potential sources of error. Useful tips for selecting the appropriate comminution principle, the optimal accessories and the importance of correctly set parameters are presented.

环境分析的快速样品制备：萃取与消解从未如此便捷高效

CEM在EDGE和Mars 6系统中呈现全新的溶剂萃取技术，涵盖理论与实践应用。EDGE系统中的溶剂萃取可在数分钟内快速完成，全程全自动运行且溶剂消耗极低。本次将详细介绍采用全新MiniClave技术的压力消解法（适用于ICP-OES等元素测定）。除理论基础与大量应用案例外，我们将通过CEM应用实验室的实时演示展示设备操作流程，在线研讨会全程开放提问环节。

Analytical solutions for the Substitute Building Materials Ordinance

The current Substitute Building Materials Ordinance presents laboratories with new analytical challenges. We have developed a new method to analyse phenols and chlorophenols quickly and effectively. The method is based on GCMS analysis and reliably delivers the load values for the individual components. We also present a package that is specially tailored to asphalt analysis.
Here, the analytical focus is on polyaromatic hydrocarbons (PAH). With this method, even inexperienced laboratories can quickly get started with reliable PAH analysis.

Topics

Why do samples have to be homogenised and what does representative mean?
How do different comminution principles affect different samples?
Application examples
Different RETSCH mills in action

Topics

Microwave digestion particularly fast in a few minutes
Solvent extraction with little solvent and small footprint
Simplest handling
Flexible choice of location thanks to the built-in exhaust air system
