“…PTR-MS instrument. This present study was performed on our home-made PTR-MS apparatus (Ion Sniffer 2020Q) as described in our previous work [21][22][23][24][25][26] and a detailed description of PTR-MS technique can be found elsewhere 21,27,28 . Briefly, the apparatus mainly contains ion source, drift tube and quadrupole mass spectrometer (QMS).…”

“…Proton transfer reaction (PTR)-MS with H 3 O þ and NH 4 þ as the reagent ions has been used to detect TATP. It was shown that in reduced electric field typical protonated [TATPþH] þ and adduct [TATPþNH 4 ] þ ions are formed, respectively (Shen et al, 2009). In recent article five different high explosives were analyzed comparatively with two different PTR-TOFMS instruments.…”

In recent years, explosive materials have been widely employed for various military applications and civilian conflicts; their use for hostile purposes has increased considerably. The detection of different kind of explosive agents has become crucially important for protection of human lives, infrastructures, and properties. Moreover, both the environmental aspects such as the risk of soil and water contamination and health risks related to the release of explosive particles need to be taken into account. For these reasons, there is a growing need to develop analyzing methods which are faster and more sensitive for detecting explosives. The detection techniques of the explosive materials should ideally serve fast real-time analysis in high accuracy and resolution from a minimal quantity of explosive without involving complicated sample preparation. The performance of the in-field analysis of extremely hazardous material has to be user-friendly and safe for operators. The two closely related ion spectrometric methods used in explosive analyses include mass spectrometry (MS) and ion mobility spectrometry (IMS). The four requirements-speed, selectivity, sensitivity, and sampling-are fulfilled with both of these methods.

“…Finally, two examples were used to illustrate this method: (1) the direct identification of cyclohexanone as the major component in the headspace of medical infusion sets, and (2) the differentiation and quantification of propanal and acetone in three synthetic mixtures with different ratios of 15.2%/84.8%, 45.8%/54.2% and 64.6%/35.4%. The demonstration of its construction and performance has been reported elsewhere [5,7,19]. The schematic of Hefei PTR-MS-01 is shown in Figure 1.…”

“…Due to its advantages, such as fast response time (to 200 ms), absolute concentration measurements, and low detection limit (low ppt range), PTR-MS has been used in many fields, such as environmental research, science and technology for food and flavour, physiology and medicine, detection of explosives and screening drug precursor chemicals in recent years [1][2][3][4][5][6][7][8].…”

Proton-transfer-reaction mass spectrometry (PTR-MS) is a powerful technique for the real time trace gas analysis of volatile organic compounds (VOCs). However, quadrupole mass spectrometer (MS) used in PTR-MS has a relatively low mass resolution and is therefore not suitable for differentiating isobars. Furthermore, because of the lack of chemical separation before analysis, isomers can not be identified, either. In the present study, by varying the reduced-field E/N in the reaction chamber with a range of 50-180 Td in PTR-MS, we studied the product ion distribution (PID) of three sets of isobars/isomers, i.e. n-propanol/iso-propanol/acetic acid, propanal/acetone and four structural isomers of butyl alcohol. The profiles of the reduced-field dependence (PFD) of the PID under the chosen E/N-values show obvious differences which can be used to discriminate between these isobars/isomers thus enabling the titled method. Noticeably, we have observed that even the isomers, in the case of four structural isomers of butyl alcohol, which show little difference with each other at high reduced-field, can be discriminated easily at low reduced-field. Finally, two examples for the application of this method are discussed: (1) cyclohexanone was identified to be a major compound in the headspace of medical infusion sets; and (2) the differentiation and quantification of propanal and acetone in three synthetic mixtures with different ratios. This study presents a potential method to distinguish and quantify isobars/isomers conveniently in practical applications of PTR-MS analysis without additional instrumental configurations.
