Mass Spectrometry
1 reportMass Spectrometry is a laboratory method for preparing, separating, detecting, quantifying, or validating samples and signals. Valid use requires quality control, accuracy, and instrument setup, with transparent assumptions and checks against bias or model misspecification.
For readers assessing Mass Spectrometry, the relevant threads are signal or separation principle, while also considering method validation and sample preparation. The strength of statements about signal or separation principle depends on how well blank and control samples is supported by interlaboratory comparison; interpretation remains cautious because matrix effects, contamination, and instrument drift can bias measurements.
