The Paradigm Shift: From Conventional HRMS and Triple Quod to Orbitrap HRMS for Impurity Profiling
Traditional HRMS systems such as time-of-flight or quadrupole instruments have supported pharmaceutical analysis for many years. However, they often face difficulties when impurities co-elute or appear at very low concentrations. Limited resolution can cause overlapping signals, leading to unclear or incorrect identification.
Orbitrap HRMS for Impurity Profiling changed this situation by offering extremely high resolving power and mass accuracy better than 1 ppm. Closely related compounds can now be separated clearly, even in very complex samples. To fully appreciate how this analytical leap works at a fundamental level, understanding the working principle of HRMS provides valuable technical clarity. Matrix interferences that once caused confusion can be confidently resolved.
As a result, impurity profiling becomes more selective and dependable. Analysts can identify and track impurities that were previously missed or wrongly assigned. The real revolution lies in the quality, integrity, and confidence of the data produced by Orbitrap systems.
