Webinar: Preparation and analysis of environmental samples  With a focus on the new Substitute Building Materials Ordinance

In environmental analysis, high demands are placed on sample preparation and analysis because the concentration of pollutants in, for example, soils, sludges, sediments or animal feed is usually low. Careful sample preparation and analysis is required to obtain accurate and reliable analytical results. The new Substitute Building Materials Ordinance also poses challenges for laboratories.

In three webinar blocks, the companies Retsch, CEM and Shimadzu offer a comprehensive presentation of reliable and efficient sample preparation and analysis. The focus will be on the reproducible homogenisation of laboratory samples, novel extraction technologies, digestion methods and the analytical methods GCMS, LCMS/MS and ICP-MS.

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.


 

Fast sample preparation for environmental analysis: Extraction and digestion easier and faster than ever before

CEM presents the new solvent extraction technologies in the EDGE and Mars 6 in theory and practice. Solvent extraction in the EDGE runs quickly in a few minutes, completely automatically, and consumes little solvent. Pressure digestions for elemental determination (e.g. ICP-OES) with the new MiniClave technology will be presented in detail. In addition to the theoretical basics and many application examples, the use of the devices will be demonstrated via live circuit from the CEM application laboratory and questions can be asked throughout the online seminar.

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.
