在线HTLC-MS/MS分析环境水质中的抗生素

Introduction

There is a growing concern over the presence of antibiotics in environmental sources of water.This has caused environmental and government labs to develop LC/MS methods to monitor water supplies for the presence of antibiotics.However,the low-level concentration of antibiotics in environmental water sources often requires extensive sample preconcentration and cleanup.

Goal

Develop a method to screen for antibiotics in surface water by applying on-line preconcentration and analyte extraction with LC/MS/MS detection.

　instrument:

TSQ Quantum Ultra

Conclusions

A method for assaying antibiotics in water sample at the lolw pg/ml level using on-line sample clean-up and preconcentration has been demonstrated.
