Identification of volatile compounds

The identification of volatile compounds of both Mo and W in gases from a municipal landfill (Feldmann and Cullen 1997) illustrated unusual transformation products. Although these compounds were tentatively identified as Mn2(CO)jo and W(CO)g, neither the mechanism of their formation nor their potential health hazards has been resolved.

Sampling and Analysis. A frozen slice of bread was cut in pieces and stacked in an enlarged sample flask of an aroma isolation apparatus according to MacLeod and Ames (74). Volatile compounds were trapped on Tenax TA and afterwards thermally desorbed and cold trap injected in a Carlo Erba GC 6000 vega equipped with a Supelcowax 10 capillary column (60 m x 0.25 mm i.d.) and a flame ionisation detector. Similar GC conditions were used for GC-MS identification of volatile compounds by dr. M.A. Posthumus (Dept. Organic Chemistry, VG MM7070F mass spectrometer at 70 eV El, 75).

Because gas chromatography (GC) is an analytical technique in which separation and identification of volatile compounds occurs, it might be considered the best technique for this kind of sample [2]. 

Identification of volatile compounds in SDE of KY 14 tobacco stalk The identification and quantitation of 25 volatile compounds in tobacco stalk which comprised about 30% of the total volatile oil isolated was facilitated by a 2-dimensional GC approach. In this technique, there was a preliminary preparative GC separation of total SDE volatiles from 9 kg stalk into about 25...

Mass spectrometry is an analytical method of choice for identification of volatile compounds and has been employed in investigation of thermolysis and acidolysis mechanisms of chemical amplification resists [96, 121, 122]. This technique has been also utilized in screening of resists systems, especially Si-containing 193 nm bilayer resists,for outgassing [438,439]. MALDI-TOF mass spectroscopy has been applied to characterization of dendritic resist polymers.
