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.
