LC-MS system replacement: Are you ready?
Meeting deadlines in a bioanalysis laboratory can be a big challenge. Older, less sensitive and less reliable LC-MS systems make it even more difficult. Even the disruption caused by the installation and validation can be disconcerting and delay decisions. Does this sound familiar?
Questions and answers to help improve your mycotoxin analysis

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.

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.

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.

Screening Food for Allergens Using LC-MS/MS Analysis
Browse the shelves of any grocery store, and you may get a false sense of security when it comes to ingredient lists. As much as consumers want to trust labels, the truth is, food products could contain mislabelled ingredients, such that they trigger an allergic reaction with serious detrimental effects including discomfort, pain sickness and in some instances, death. Manufacturers, however, do not want to risk their reputation and consumer safety over a false label. As such, there must be some sort of verification to support such an action
