High Resolution Time-of-Flight Mass Spectrometry for the Identification of Pharmaceuticals in Water Samples

摘要

Accurate mass, using time-of-flight mass spectrometry (TOF) instruments, has been the method of choice for many scientists in the environmental field in order to identify and detect organic contaminants, such as pharmaceutical and pesticides, in complex matrices. The increase in resolving power in the last 4-5 years has been one of the main achievements leading the instrumentation market. In many cases the resolving power of TOF instruments has doubled the previous ones, thus opening up a wide range of possibilities for unequivocal identification and interference discrimination of environmental relevant compounds in complex samples.
