It’s true that many vendors position triple quadrupole instruments as “GMP‑ready,” largely because they are well established for targeted, quantitative assays and are easier to validate in a traditional sense.

However, triple quadrupoles are not a requirement for GMP‑level analysis. GMP compliance is not dictated by the type of mass spectrometer, but by how the method and the overall analytical platform are implemented, qualified, and controlled.

High‑resolution MS systems, which are commonly used for HCP profiling, can also be fully GMP‑compliant, provided that the method is properly validated, the instrument is qualified (IQ/OQ/PQ), and the software and data workflows meet data integrity requirements.

In practice, the choice of instrument depends on the analytical objective. Triple quadrupoles are typically preferred for highly targeted, routine quantification, whereas high‑resolution MS offers clear advantages for global HCP profiling and identification. Both approaches can operate within a GMP framework, as long as they are appropriately qualified and validated for their intended use.

Thomas Kofoed, PhD, CEO of Alphalyse in Denmark, discussed key factors in implementing GMP-compatible LC-MS methods for release assays and highlighted successful cases where this approach has replaced traditional ELISA methods. Don’t miss his presentation and expert insights at the panel discussion.
