Matrix effects in LC-MS can be managed but not completely avoided.
research The use of electron spin resonance techniques to determine gamma ray exposure of $\alpha$-keratin in human hair
Whole hair strands can reliably measure gamma ray exposure using ESR techniques, but samples should be analyzed quickly or stored in liquid nitrogen.
research SRXRF elemental mapping and source analysis of Pb,Fe,Cu and Zn in human hair from an inhabitant in a lead-zinc mining area
Lead levels in hair increased due to environmental exposure, while iron, copper, and zinc levels stayed stable.
research Use of rotary echoes in 2 H
A new method accurately measures molecular movement without complex modeling.
research The influence of sulfur and hair growth on stable isotope diet estimates for grizzly bears
Sulfur slightly improved diet estimates for grizzly bears, but hair growth timing varied, affecting results.
research Matrix matching in quantitative bioanalysis by LC–MS/MS a dream or a reality?
Accurate quantitative bioanalysis using LC-MS/MS is challenging due to matrix effects, but using internal standards and new methods like in-sample calibration could improve results.
