Azimsulfuron may be used as an analytical reference standard for the determination of the pesticide in:
- Paddy field water by direct injection using liquid chromatography-hybrid triple quadrupole-linear ion trap-mass spectrometry (LC-QqLIT-MS).
- Tap and leaching water samples by solid-phase extraction (SPE), followed by LC coupled to tandem mass spectrometry (LC-MS/MS).
