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
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.

What has the Echo® MS system done for the pharma industry? (And don’t just take our word for it!)
SCIEX was very proud to have an illustration of the Acoustic Ejection Mass Spectrometry (AEMS) technology that powers the Echo® MS system on the front cover of the Journal of the American Society for Mass Spectrometry in January 2023. The associated article—Ultrahigh-Throughput Intact Protein Analysis with Acoustic Ejection Mass Spectrometry—was co-authored by scientists from SCIEX and Merck.

Back to the new basics: Part 1 | Making the leap from GC-MS to LC-MS
Producing accurate results quickly in a demanding environment is no easy feat for analytical scientists. What’s more, many of us are constantly questioning ourselves—I certainly am—about whether we are employing the best technique for the analysis at hand.
It’s an overwhelming thought, considering the wide range of tools that are available to choose from, each of which offers varying levels of capacity, sensitivity, selectivity, specificity and cost. How do you meet the unique needs of your organization without breaking the bank? I get it, and I’m not here to convince you it’s easy. My aim is to guide you through the process to help you make the right decision for you.
Short-chain PFAS compounds are on the rise- Craig’s PFAS Vodcast Cora Young
Read time: 2 minutes Short-chain per- and polyfluoroalkyl substances (PFAS) are increasing in the Canadian Arctic environment, with the most rapid increases occurring post-2000, according to a recent study in Geophysical Research Letters (April 2020). For example,...
Identifying the unknown PFAS profile in firefighting foams/AFFF
According to a recent study from Harvard University, the US EPA, and NIEHS, traditional targeted analysis techniques poorly characterize the PFAS composition of contemporary PFAS-based firefighting foams, know as aqueous film-forming foams (AFFF). Using the EPA 533 PFAS drinking water method for the analyte list, the researchers found that targeted mass spectrometry methods accounted for <1% of organic fluorine content. This is important because it demonstrates that targeted analysis methods miss nearly all the PFAS compounds in modern AFFF mixtures, thus underestimating the risk to human health and the environment.
High complexity of the lipidome
The complexity of the lipidome is diverse in the structure and there are many combinatorial isoforms that are available within nature. Currently, many different techniques are required to fully characterize a lipid molecule. What if you could do it in a single...

Standard addition workflow – for quantification and calculating background levels
The method of standard addition is a quantitative analysis approach used in situations where matrix effects from complex samples contributes to the analytical signal. This makes it impossible to compare the analytical signal between sample and standard using a...
How do I define the experimental design (the metadata) for my SWATH acquisition study within the OneOmics suite? What are the requirement for replicates?
In quantitative Omics research, the goal is to understand which analytes (protein or metabolite) are perturbed between experimental conditions; therefore we carefully design our studies to explore these questions. The algorithms used within the Assembler application...

The risky business of aflatoxins in milk
If you’re in the dairy or food testing business, you know the threat aflatoxins pose. Aflatoxins are a type of mycotoxin produced by Aspergillus parasiticus, aspergillus flavus , and rarely aspergillus nomius.1 These are likely the most extensively researched group of mycotoxins because of their adverse health effects.2 What’s more, they are widely found in a variety of crops, namely maize, tree nuts, and spices. Believed to be primarily caused by rising temperatures and humidity, these naturally occurring fungi grow on crops in the field, or during storage of feed and raw materials, where they can potentially produce toxins that enter the food chain.
