The honey sting

As a consumer it’s hard for me not to feel inundated with claims that our food is “all-natural” or “chemical-free” or that we should buy certain “superfoods” for their health benefits.  We read labels and trust that the product we are buying is what we are truly...

A rising star in food allergen research: proteomics of shellfish allergen

It’s important to know what you’re eating, especially if you suffer from a food allergy.

About 220 million people worldwide live with a food allergy.1 These numbers, along with the complexity and severity of conditions, continue to rise. In America, there are about 32 million food allergy sufferers—5.6 million of those are children under the age of 18.2.2 That’s 1 out of every 13 children, or about 2 in every classroom. From a financial perspective, the cost of food allergy childcare for US families is up to $25 billion

Overcoming uncertainty in your PFAS analysis

Overcoming uncertainty in your PFAS analysis

Just like gum on the bottom of a shoe, the existence of per- and poly-fluorinated alkyl substances (PFAS) in our environment is a sticky one. If you’re in the field of environmental testing, then you’re all too familiar with the threat these substances have on public health. While we have learned a lot about them over the years, there is still much more to understand. With the right detection methods, we can gather the information we need to empower us to make informed decisions on reducing the risks they impose.

Nitrosamines: Where are we now?

Nitrosamines: Where are we now?

Nitrosamines are a large group of N-nitroso compounds that share a common functional N-N=O group. They are produced by a chemical reaction between a nitrosating agent and a secondary or tertiary amine. Back in 2018, nitrosamines suddenly found themselves in the spotlight when they were unexpectedly detected in medications for high blood pressure. Since then, they have been found in several other prescription medications, including those for heartburn, acid reflux and diabetes, resulting in manufacturers recalling some common medications.

Detecting low levels of drugs and their metabolites in hair and nail samples using LC-MS/MS

Detecting low levels of drugs and their metabolites in hair and nail samples using LC-MS/MS

You probably have heard of testing blood and urine samples for the presence of drugs and their metabolites. But do you know about the benefits of hair and nail analysis? In a recent webinar, Tina Binz, Deputy Head of the Center for Forensic Hair Analysis, University of Zurich, discussed the benefits of developing comprehensive and sensitive LC-MS/MS for the detection of low-level drugs and metabolites in keratinized matrices.

Guide decisions during cell line development with more information at the intact level

Guide decisions during cell line development with more information at the intact level

Monitoring product quality attributes (PQAs) throughout monoclonal antibody (mAb) development is vital to ensuring drug safety and efficacy. By adopting orthogonal analytical techniques and integrating new technologies that have the potential to provide more information, it is possible to improve product quality and manufacturing efficiency and make more informed decisions.

Maximize NPS analysis with accurate mass spectrometry

Maximize NPS analysis with accurate mass spectrometry

LC-MS/MS is a powerful analytical tool in forensic toxicology testing that can support a variety of testing regimes such as screening, confirmation and quantitative workflows. More specifically, analysis of NPS using LC-MS/MS provides many advantages, including the ability to reliably detect new drugs and their metabolites from a variety of biological matrices.

Unlock the benefits of nominal mass spectrometry for NPS analysis

Unlock the benefits of nominal mass spectrometry for NPS analysis

The development of analytical methods for the detection and quantitation of drugs and metabolites in a range of biological matrices is a challenging process. Forensic toxicology labs need a reproducible and reliable methodology to ensure the robustness of the data and the quality of the results. They also need robust and sensitive instrumentation that can detect drugs at trace levels with high specificity, especially when it comes to novel psychoactive substances (NPS), which can be difficult to monitor and control.
