massabias
Massabias is a term used in metrology and data analysis to describe a systematic bias in estimated mass values that varies with the mass scale or analytical context. The term blends mass and bias and is used to discuss errors that persist across measurements even after standard processing.
In practice, massabias may arise in mass-based measurements such as mass spectrometry, gravimetry, or astrophysical mass
Common causes include calibration drift, mass-dependent detector efficiency, nonlinear amplification, matrix effects, and data processing steps
The presence of massabias can lead to consistent over- or underestimation of mass, affecting derived quantities
Detection and mitigation involve using multiple calibrants spanning the mass range, cross-checking with orthogonal measurements, applying
