If you are working with complex assays that demand exceptionally selective quantitative and qualitative performance, sometimes even the most powerful LC-MS/MS technology can’t always cut it alone.
Perhaps you are struggling to separate isobaric species, isolate challenging co-eluting analytes or reduce high background noise? Regardless of your challenge, the outcome is the same. You probably aren’t getting the levels of quantitation or characterization you need, so method development has become cumbersome, and workflow performance is suffering.
Now you can bring a new dimension of selectivity to your LC-MS/MS analysis on select SCIEX Triple Quad™, QTRAP® and TripleTOF® Systems with SelexION® Differential Mobility Separation (DMS) Technology. The SelexION DMS cell:
Harness the power of differential mobility separations to simplify your sample preparations, while achieving unprecedented levels of selectivity. Find out more by downloading the SelexION brochure.
How does it work?Gas phase differential mobility separation within the SelexION device planar mobility cell is based on the ion’s size and shape, and the difference between their unique differential mobilities across high and low energy fields. Gas phase separation occurs prior to entering the mass analyzer where the compounds are then further separated by m/z ratios.
Waterproof jackets. Stain-resistant shoes. Easy-clean fabrics are marketed as “performance.” Behind those everyday claims sits a class of chemicals now reshaping regulation, brand accountability, and laboratory science: PFAS.
For decades, SCIEX has been part of bioanalytical innovation, empowering scientists in pharma and biopharma to push the boundaries of sensitivity, accuracy, and throughput. Across complex workflows and increasingly challenging therapeutic modalities.
Trifluoroacetic acid (TFA) is emerging as one of the most concerning ultrashort-chain PFAS in Europe’s food supply – particularly in cereals, a staple consumed daily by millions. A report from PAN Europe reveals a widespread and largely unmonitored contamination trend that raises serious questions about food safety, regulatory blind spots, and future monitoring strategies.
