[Analysis Case] High-Sensitivity Analysis of Nitrogen Compounds by GC
Analysis of nitrogen compounds using GC/MS/NPD (Nitrogen Phosphorus Detector).
When analyzing samples containing nitrogen compounds using GC, simultaneous measurement with MS (mass spectrometer) and NPD (nitrogen-phosphorus detector) allows for the detection of components that do not appear as peaks in the MS, enabling the acquisition of MS spectra from their retention times for qualitative analysis. In this case, a sample containing trace amounts of the nitrogen-containing compound trimethylamine was measured using GC/MS/NPD. A peak that was buried in the baseline in the MS was confirmed by the NPD, allowing for the qualitative identification of trimethylamine from the mass spectrum at the same retention time.
