Spectra nitroglycerine

FIGURE 3 Positive-ion atmospheric pressure chemical ionization mass spectrum at retention time approximately 13.7 minutes for nitroglycerin tablet sample. 

Lemanccau and Caire-Maurisier (4) examined NMR spectrum of nitroglycerine with a view to determining the conformation of the compound. The spectrum is of the type ADCA B and appears to favour the ecliptic conformation of C-ONO2 groups. 

FIGURE 7.6 The first ion mobility spectrum generated from the light emitted from ion-ion recombination. The two peaks are a sharp reactant ion peak with a of 2.17 em A s and a product ion peak of nitroglycerin with a of 1.35 cmW s. (From Davis et al..

Example Still under the impression of the 2001 terrorist attack on the World Trade Center, ambient MS initially had a strong focus on the detection of explosives. Negative-ion DART is very sensitive for the analysis of explosives exhibiting extremely low but non-zero vapor pressure [58]. Nitroglycerin has been detected on a man s necktie 8 h after exposure to the plume from blasting at a construction site (Fig. 13.20a) and various explosives present at about 3 ppm in a contaminated pond water sample have been detected placing a small open bottle with 0.1% aqueous trifluoroacetic acid (H-TFA) in proximity to the sanpling zone caused them to appear as [M+TFA] adduct peaks in the DART spectrum (Fig. 13.20b) [2].
