An investigation into detector dead time variability and mass dependency in quadrupole ICP-MS and implications for isotope ratio accuracy

Key Points

• Detector dead time influences isotope ratio outcomes in Q-ICP-MS instruments.
• Key findings indicate that variations are affected by laboratory conditions and detector age.
• Observational analysis examines the relationship between mass dependency and detection accuracy using Q-ICP-MS.
• Implications suggest that correction for dead time is necessary to enhance isotopic measurement reliability.
