Analysis of Nine N-Nitrosamines Using Liquid Chromatography-High-Resolution, Accurate-Mass Mass Spectrometry

Instrument Type: LCMS

N-nitrosamines present high mutagenic and carcinogenic potential. They or their precursors occur in a wide variety of foods and natural and manufactured products. An analysis method for nine N-nitrosamines based on ultra-high performance liquid chromatography combined with high-resolution, accurate-mass (HRAM) mass spectrometry is presented here.

Determining Nitrosamines Using GC-MS/MS with Electron Ionization

Instrument Type: GCMSMS

The highly sensitive TSQ Duo triple quadrupole mass spectrometer can analyze nitrosamines in EI mode. Using automatic selected reaction monitoring (AutoSRM) software to fully optimize the choice of transitions and collision energies, equivalent detection limits by EPA method can be achieved without using a large volume injection.

High resolution analysis of nitrosamines in EPA 8270

Instrument Type: HPLC

The Thermo Scientific HPLC system is applied for the analysis of nitrosamines in EPA 8270. The separation is performed on a Thermo Scientific Acclaim PolarAdvantage (PA) column, with UV detection at 230 nm.
