In January the European Chemicals Agency expanded the Candidate List of substances of very high concern (SVHC). Four hazardous chemicals were added to the Candidate List, which now contains 223 entries for chemicals that can harm people or the environment. Companies are now responsible for providing sufficient information to their customers and consumers. Developing analytical techniques to monitor these chemicals is the first step. At ADKL Labs we have already worked on the identification and...

At ADKL Labs we’ve recently had a few de-formulation projects and this has presented a great opportunity to describe the process for those unfamiliar. How do you go about identifying the composition of a product? How do you do it without spending a huge amount of time and money? The chemical composition of products can vary widely and naturally requires a wide array of analytical techniques to decipher. Over the years this has also resulted in a variety of approaches to solving such problems,...

Author: Dragan Krsta At ADKL Labs a recent project was centred around emerging Persistent Organic Pollutants (POPs). Exposure to POPs can lead to serious health effects and the analysis and monitoring of such substances is critical to ensuring a safe environment for us all. We found the topic very interesting and eye opening. Below we have some background information on this project focused on short-chain chlorinated paraffins (SCCPs). In the past, SCCPs were mostly used as coolants in metalwork...

Author: Dragan Krsta During a recent Introduction to Gas Chromatography workshop at ADKL Labs the topic of sample discrimination came up. Many factors combine to impact sample discrimination and a thorough understanding of the sample and chromatography system are required to address the issue. The workshop concluded with a wonderful set of example data to demonstrate inlet discrimination, which we’ve shared below. Most users will be familiar with a version of discrimination. For example,...

Author: Dragan Krsta Are methods getting more complex or do we have higher “quality” expectations? The days of “in-house” methods are long gone, or are they? Depending on where you are in the world the need for accreditation often limits the analyses your laboratory can perform. But in most cases the design, development and validation of methods is left to the laboratory performing them. Only the data and quality systems are accredited. Therefore, we see laboratories carry forward legacy...
