Rapid and Efficient Filtration-Based Procedure for Separation and Safe Analysis of CBRN Mixed Samples
Figure 2
Representative mass spectra for EMPA and PMPA surrogates and PEG-400 after liquid chromatography analysis coupled to LC/TOFMS. The ESI negative ion mode was used. Measurement of peak areas of PMPA and EMPA was based on the EIC at 179.08±0.05 m/z (A) and at 123.01±0.05 m/z (B), respectively. (C) Mass spectrum of PEG-400 was assessed with the ESI positive ion mode while measurement of the peak area was based on the BPC.
