LC-MS/MS分析蓝绿藻中的微囊藻毒素

 Introduction

Overgrowth of algae is a common problem in many wetlands with advanced stages of eutrophication(the enrichment of chemical nutrients containing nitrogen or phosphorus in an ecosystem).This often results in a thick,colored layer on the water's surface,known as an algal bloom.Some of the algae that grow in these bodies of water,known as Cyanobacteria or blue-green algae,produce toxic compounds known as microcystins.

Among them are Microcystin-LR,YR and RR,which have been detected in wetlands in Japan.This application note reports on the analysis of these microcystins by using LC-MS/MS.

Instrument

TSQ Quantum Ultra

Conclusion

Microcystin-LR,YR and RR can be quantitatively analyzed over four orders of dynamic range(0.1 ppb-1.0 ppm)by using the TSQ Quantum Ultra triple quadrupole LC-MS/MS system from Thermo Fisher Scientific.
