Chiral and Achiral Profiling of Crop Protection Chemicals using UltraPerformance Separations and Mass Detection

Before marketing a new chemical, the manufacturer/importer, in order to meet the various national and international legal requirements, has to submit information in the form of a notification or registration (e.g. phys-chem, toxicological, ecotoxicological data) to support each Government’s risk assessment to determine whether the substance poses an unreasonable risk to the environment and/or human health. Some countries require pre-manufacture/import notification while for many jurisdictions, the chemical notification process is a tiered system requiring subsequent notifications as the annual amount of the imported or manufactured substance increases. Further, there are expanding global initiatives to assess chemicals already in the marketplace and subsequently take action on any chemicals found to be harmful to human health and/or the environment.

Nanocellulose is an interesting material with unique properties and chemistry. Cellulose, the structural component of the primary cell wall of green plants, is the most abundant organic material on the planet and because of its useful materials properties it is one of the most widely used substances.

The European Chemicals Agency (ECHA) recently added 10 new substances to the Registration, Authorisation, Evaluation and Restriction of Chemicals (REACH) Substances of Very High Concern (SVHC) Candidate List. Raj Takhar, Assent’s Subject Matter Expert, Materials Management and Chemical Reporting, and Valerie Kuntz, Materials Management Subject Matter Expert, discuss these substances and the requirements for reporting on them.

The elemental analysis of petrochemical products such as crude oils, intermediate refinery products, automotive fuels, or modern lubricating oils is quite challenging. If you work with Atomic Absorption Spectroscopy (AAS) or Inductively Coupled Plasma Spectroscopy (ICP), the organic matrix of petrochemical products requires special attention during sample preparation and instrument adjustment. Here, X-ray Fluorescence (XRF) is really different and brings a lot of benefits to your lab, including simple sample preparation and elimination of daily re-calibrations. During this webinar, you will learn more about why sample preparation in XRF is so simple and straight forward and how the comprehensive XRF portfolio from Bruker can boost your sample throughput for such demanding applications. We will provide information that will help you to decide if an Energy Dispersive X-ray Fluorescence (EDXRF) or a Wavelength Dispersive XRF (WDXRF) instrument is the best choice for your specific petrochemical application.
