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.

Short-chain PFAS compounds are on the rise- Craig's PFAS Vodcast Cora Young

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, trifluoracetic acid (TFA) in the Devon Ice Cap increased ~10-fold from 1.4 μg/m2 per year during 1977–1989 to 10.3 μg/m2 per year during 2001–2014. The authors of the study suggest that the increased short-chain PFAS concentrations post-2000 were from new chlorofluorocarbon (CFC) replacement chemicals produced as a result of the 1987 Montreal Protocol treaty. One of the paper’s lead authors, Professor Cora Young of York University in Toronto, Ontario, discussed the study findings during the inaugural episode of my new video podcast, “PFAS fireside chats with Craig Butt.

The metabolome: the way to personalized healthcare?

The completion of the human genome project in 2003 opened the door to unprecedented insight into the human body through its DNA code. We now know that our genome encodes our proteins, that our proteins are the molecular machinery of certain functions that take place in our cells and that the end products of these functions are our metabolites.

Not all cannabis is created equal: cannabis strains explained

Cannabis strains not only have different effects, but also serve different purposes. In the mainstream world, cannabis is grouped into 3 distinct strains: Indica, Sativa and hybrid. Indica strains are of Hindu Kush Mountain origins, and they are high in tetrahydrocannabinol (THC) content and dense cannabidiol (CBD). They are often believed to be relaxing and are used in pain management. Sativa strains, on the other hand, have a more energizing effect, and hybrid strains are a combination of Indica and Sativa.1

Mass spectrometer analysis gives you one more reason for taking a shower before swimming!

Swimming is a favorite summer pastime for many, and swimming pools are frequent destination for this activity. Of course, keeping the water in swimming pools clean means the use of disinfectants, and researchers at the University of Alberta in Canada published some insightful findings in this area. Wei Wang and coworkers in the university’s Division of Analytical and Environmental Toxicology conducted a study using the SCIEX Triple Quad™ LC-MS/MS System to quantify the presence of halobenzoquinones (HBQs), a class of disinfection byproducts (DBPs) of health relevance, in swimming pools.

Intabio acquisition expands SCIEX portfolio of impactful solutions to accelerate biotherapeutic development

Due to the nature of their production, biotherapeutics are difficult to manufacture. Growth conditions, purification protocols and formulation requirements can introduce unintended modifications into the protein structure that may affect its efficacy and safety. Imaged capillary isoelectric focusing (iCIEF) provides a critical measure of quality throughout the development and manufacturing of biotherapeutics by offering rapid, robust and high-resolution charge variant analysis.

Quantify more than 700 pesticides in 10 different food matrices

A recent webinar from SCIEX and New Food, presented by Jianru Stahl-Zeng of SCIEX, outlined some of the capabilities of the new SCIEX Triple Quad™ 7500 LC-MS/MS System – QTRAP® Ready. In particular, it highlighted the ability of the SCIEX 7500 System to accurately quantify 700 pesticide residues across 10 different food matrices at ultra-low trace levels. During the webinar, attendees posed various questions. Here, we share the top 5 of these questions, along with their answers.

Should you bring your PFAS testing in-house?

As the per- and polyfluoroalkyl substances (PFAS) regulatory landscape evolves in the US and across the globe, the interest in PFAS continues to grow. Drinking water and food packaging are under particular scrutiny, and monitoring programs and requirements will continue to expand to include an increasing variety of sample types and PFAS compounds.

I'd like to be among the first to get my hands on new SCIEX solutions.
