Mechanical engineer Mason Chilmonczyk, PhD (Andson Biotech) joins host David Oliva to explain why sample prep — not the mass spec itself — is the biggest bottleneck in LC-MS and native MS workflows. Mason breaks down the DynaChip, a microfluidic device that shrinks hours of buffer exchange into seconds, and shares how "democratizing" mass spec is opening the door for cell therapy manufacturers to catch analytical blind spots that traditional workflows miss. A must-listen for anyone working

If you take a handful of dirt from the roadside, it contains PFAS. The challenge isn't finding forever chemicals — it's finding all of them. Standard monitoring methods cover 40 to 50 PFAS species. Thousands more go completely unmeasured. That's the gap Dr. Viktoria Müller has spent her career trying to close.Viktoria is a postdoctoral researcher at the University of Graz specializing in PFAS environmental fate, transport, and the fluorine mass balance. Her work spans ski slopes, rivers,
