Determination of Endocrine Disrupting Chemicals in Drinking Water at Sub ng/L Levels using Direct Injection and Triple Quadrupole Mass Spectrometry

摘要

The increased sensitivity of the 6495 Triple Quadrupole enabled a streamlined analytical workflow with direct injection of tap water samples instead of time-consuming sample preparation procedures such as offline solid phase extraction. Furthermore, quantitative performance based on signal response precision was used to demonstrate the instrument's sensitivity with IDLs ranging from 0.02 to 0.78 ng/L.
