Determining Oxidation Induction Time by DSC

Oxidation is a chemical reaction in which a substance loses electrons, either by the addition of oxygen or by the removal of hydrogen. The oxidation of materials can lead to failure in their particular use or application. For example, polymers become brittle, edible oils become rancid, mineral oils undergo polymerization, and petrochemical products exhibit a change in viscosity.

Analysis of Allergens: New European Regulation

Fragrance allergens are molecules often present in cosmetic products that can trigger allergic reactions in sensitive individuals. These are not intentionally added ingredients by cosmetics manufacturers, but rather substances naturally occurring in the components that make up the fragrance.

In 2012, the European Scientific Committee on Consumer Safety (SCCS) identified 82 fragrance substances that can cause allergies in humans. On July 26, 2023, the European Commission published Regulation 2023/1545, amending Regulation (EC) No 1223/2009 of the European Parliament and of the Council. This regulation pertains to the labeling of allergenic substances in cosmetic products. The historical list of 26 allergens has now been expanded to 82 compounds. Synthetic fragrances and essential oils contain allergens classified as “risky” ingredients.

Join us in this webinar to discover the Agilent solutions for analyzing these allergens using GC/MS.

Thermal Analysis of Lithium-Ion Batteries

The increasing market of consumer electronics, smartphones, and electric vehicles is pushing battery research forwards to provide safer, lower-cost, and lightweight/high-capacity solutions. For example, investigating the safety risks associated with thermal runaway is particularly important for lithium-ion batteries in electric vehicles.

Thermal Analysis Techniques for Battery Analysis

Thermal analysis techniques play a vital role in the successful research and development of advanced battery technology. They are also ideal for carrying out routine quality control checks on finished products. The four main techniques of DSCTGATMA, and DMA are particularly effective for investigating temperature-dependent effects such as glass transition, crystallization, melting behavior, purity, visco-elastic behavior, expansion, shrinkage, and decomposition. Evolved gas analysis combined with TGA can also provide important information regarding the products of decomposition.

Elemental Analysis in Yeast Cells and Microplastics by ICP-MS with Automated Micro-Flow Sample Introduction

Nanoparticle and Single Cell Elemental Analysis by ICP-MS has become popular in recent years due technological advancements in ICP-MS, as well as increasing needs for applications in various technical areas. On the other hand, microplastics have been the topics of discussions and research as its increasingly important role in environmental applications.

Various analytical techniques have their own limitations, such as the ability of particle characterization, particles sizes, and methods of sample introduction. In the current study, an automated, micro-flow autosampler in combination with a triple quadrupole Inductively Coupled Plasma-Mass Spectrometry (ICP-QQQ) is used in the elemental analysis of yeast cells and microplastics.

Applications for Predictive Dissolution Testing

With the discussions and initiatives around real-time release testing, we want to look at how this topic could influence what dissolution testing looks like in the future. While we certainly cannot avoid dissolution testing entirely, reduced testing could be on the horizon. There are many questions to ask, and we will try to give some guidance on this exciting topic. What are the hurdles; who are the early adopters? Are all products and workflows suitable for this new approach? Do you already have experience with the topic? Then please share it with us and the audience.

Thermal Analysis of Organic Compounds

Small and medium-size organic molecules of natural or synthetic origin are often used as raw materials, additives, active ingredients, or processing aids in many industries. Because many of their properties are temperature dependent, thermal analysis techniques are an excellent tool for the successful characterization of these compounds.

Important Types of Analysis for Organic Chemistry

The field of organic chemistry covers the synthesis, isolation, purification, and reactions of organic materials. During synthesis and work-up processes, it is important to ensure that the desired compounds have been produced and to verify their respective concentrations. At this stage, the focus is mainly on reaction kinetics and safety investigations. When the final product has been isolated, properties such as purity, stability, polymorphism, melting, and reactivity are important. Many of the analytical methods used in these investigations rely on thermal analysis techniques such as DSCFlash DSCTGAevolved gas analysis, and thermo-optical analysis.
