• Faster run times for GLP-1, insulin, and LNP drug substance testing accelerates biopharmaceutical development timelines and reduces production bottlenecks.
• Delivers up to 2x increase in resolving power and sensitivity to identify and track low-level impurities for improved regulatory readiness.
• Industry-first chemical and physical particle optimization delivers reproducible methods for increasingly complex biologics.

MILFORD, Mass., June 8, 2026 /PRNewswire/ -- 55th International Symposium on High Performance Liquid Phase Separations and Related Techniques—Waters Corporation (NYSE: WAT) today announced the launch of the BioResolve™ Peptide and GTxResolve™ Lipid Phenyl-Hexyl+ and C18+ Columns, a first-of-its-kind reversed-phase (RP) column platform designed to tackle a persistent biopharmaceutical challenge: reliably separating structurally and chemically similar impurities in GLP-1 peptides, insulin, and lipid nanoparticles (LNPs) to support the development of safe, effective drug products.

In GLP-1 receptor agonists and newer mRNA-based therapies such as in vivo CAR T, difficulty resolving impurities can delay time to market, weaken regulatory confidence, and affect patient safety. Traditional RP columns do not always separate low-level or closely related impurities well, often requiring longer analyses, detector-suppressing mobile-phase additives, or repeated method redevelopment. BioResolve Peptide and GTxResolve Lipid Columns help to overcome these limitations with ready-to-use methods that improve both resolution^1,2 and speed^2,3 while fitting into existing workflows.

"We have made simultaneous advances in both chemistry and particle physics to deliver the first columns Waters has introduced to market specifically QC batch-tested for GLP‑1 analysis⁴ and lipid nanoparticles,² solving a longstanding customer pain point," said Erin Chambers, Vice President, General Manager, Consumables & Lab Automation, Waters Analytical Sciences, Waters Corporation. "BioResolve Peptide and GTxResolve Lipid Columns are designed to resolve chemically similar GLP‑1 impurities and LNP components faster when speed matters,^2,3 and with extraordinary resolution¹ when certainty is required. The result is simpler method development, regulatory‑ready data,⁵ and faster, highly reproducible methods, ultimately helping to reduce cost burdens on important new therapeutics."

BioResolve Peptide and GTxResolve Lipid Columns use specially designed surface chemistries and superficially porous particles to deliver precise RP separations with selectivity for two difficult sample types. Available in Phenyl-Hexyl+ and C18+ chemistries with 230 Å pore size particles, they are designed to support efficient mass transfer, consistent performance across U(H)PLC and HPLC systems, and reliable, batch-tested results⁵ from early-stage research through manufacturing.

GLP-1 peptides are especially challenging to analyze because many impurities differ by just one atom, while others have no difference in atomic composition and vary only in how their atoms are arranged spatially. BioResolve Peptide Phenyl-Hexyl+ and C18+ Columns are built to resolve these difficult impurities, with specialized 300 mm formats available when maximum separation performance and deeper impurity characterization are required.

"The BioResolve Peptide RP Columns have performed exceptionally well, showing outstanding resolution between our peptide therapeutics and related impurities," said Ashish Kanhed, Group Leader, Alembic Pharmaceuticals. "We are highly impressed with their quality and look forward to continuing to use them for our complex GLP-1 and peptide separations. By discriminating critical impurities at speed with a mass spectrometry-based QC approach, we can now satisfy present and future regulatory requirements in one run for faster, more confident answers on molecular purity."

For LNP and lipid workflows, the charged surface of GTxResolve Columns helps sharpen peaks for ionizable lipids by reducing tailing. Their larger pore size makes it easier for a wide range of lipid molecules to move through the column, improving peak shape and resolving challenging co-elutions. In addition, the superficially porous particle design speeds the movement of molecules through the stationary phase, shortening run times without reducing selectivity.²

"GTxResolve Lipid RP Columns have demonstrated strong performance for lipid quantitation and impurity analysis, with reduced run times and excellent peak shape," said Adam Kowalczyk, Research Scientist II, Analytical Development, Acuitas Therapeutics. "The ability to tune separations for specific lipid components, combined with compatibility across multiple detector platforms (UV, MS, ELSD, and CAD), provides significant flexibility for characterization of diverse lipid species. In particular, we have observed a separation of ionizable lipids that has not previously been achieved."

Waters' BioResolve Peptide and GTxResolve Lipid Columns will be available globally beginning June 9, 2026, starting with the 1.6 µm Phenyl-Hexyl+ phase.  For more information, please visit waters.com/BioResolve and waters.com/GTx.

Im Insolvenzkomplex rund um den einstigen Signa-Konzern steht Firmengründer René Benko vor einem weiteren Strafverfahren. Die österreichische Wirtschafts- und Korruptionsstaatsanwaltschaft (WKStA) hat beim Landesgericht Innsbruck erneut Anklage wegen schweren Betrugs und Schädigung von Gläubigerinteressen (betrügerischer Krida) eingebracht. Der 49‑jährige Investor befindet sich seit Januar 2025 in Untersuchungshaft. Die neue Anklage ist nicht rechtskräftig, es gilt die Unschuldsvermutung, Benko bestreitet sämtliche Vorwürfe.

Kern des aktuellen Verfahrens ist eine Garantieerklärung gegenüber einem Investor beziehungsweise den Vertretern einer Privatstiftung, hinter der nach Medienangaben der frühere Strabag‑Chef Hans-Peter Haselsteiner stehen dürfte. Nach Darstellung der WKStA soll Benko eine „wahrheitswidrige Garantie“ abgegeben und die Stiftung dadurch um rund fünf Millionen Euro geschädigt haben. Konkret sollen die vertretungsbefugten Organe der Stiftung durch die Erklärung dazu veranlasst worden sein, etwa 3,3 Millionen Euro an die Signa Holding zu überweisen und auf die Rückforderung weiterer rund 1,7 Millionen Euro zu verzichten.

Der Garantie zufolge sei der Privatstiftung eine Zahlung von in Summe rund fünf Millionen Euro bis spätestens 30. Juni 2024 zugesichert worden. Diese Rückzahlung sei jedoch ausgeblieben, so die Anklagebehörde. Dadurch soll die Stiftung in Millionenhöhe geschädigt und im Gegenzug die Signa Holding sowie eine weitere Gesellschaft unrechtmäßig bereichert worden sein. Neben dieser angeblichen Falschgarantie wirft die WKStA Benko vor, im Zuge der Signa-Insolvenz sowie seiner persönlichen Insolvenz ein Jagdgewehr im Wert von rund 80.000 Euro vor den Gläubigern verborgen zu haben und damit deren Befriedigung vereitelt zu haben.

Benko war über zwei Jahrzehnte eine der prominentesten Unternehmerfiguren im deutschsprachigen Raum. Mit einem dicht verschachtelten Geflecht aus Immobilien- und Handelsbeteiligungen baute er das Signa-Imperium auf, zu dem zeitweise auch die deutschen Warenhausketten Karstadt und Kaufhof gehörten. Steigende Zinsen, höhere Baukosten und aggressive Zukäufe trugen letztlich zur Insolvenz des Konzerns bei. Im weitläufigen Signa-Komplex wird der ehemalige Milliardär von der WKStA unter anderem wegen Betrugs, Untreue und Bankrotts verdächtigt; weitere Anklagen hält die Behörde für möglich.

Der Investor ist bereits in zwei ähnlichen Verfahren verurteilt worden, beide Urteile sind jedoch noch nicht rechtskräftig. Im Oktober 2025 verhängte ein Gericht eine zweijährige Haftstrafe, im Dezember desselben Jahres folgte wegen Schädigung von Gläubigern eine weitere Verurteilung zu 15 Monaten auf Bewährung sowie eine Geldstrafe. Parallel dazu laufen mehrere Ermittlungsstränge, die auch andere frühere Führungskräfte aus dem Signa-Umfeld betreffen. Die jetzige Anklage erhöht den juristischen Druck auf Benko weiter und dürfte die Aufarbeitung einer der spektakulärsten Unternehmenspleiten im deutschsprachigen Raum zusätzlich in die Länge ziehen.
