Abstract. An active capillary plasma ionization (ACI) source was coupled to a handheld mass spectrometer (Mini 10.5; Aston Labs, West Lafayette, IN, USA) and applied to the direct gas-phase detection and quantification of chemical warfare agent (CWA) related chemicals. Complementing the discontinuous atmospheric pressure interface (DAPI) of the Mini 10.5 mass spectrometer with an additional membrane pump, a quasi-continuous sample introduction through the ACI source was achieved. Nerve agent simulants (three dialkyl alkylphosphonates, a dialkyl phosporamidate, and the pesticide dichlorvos) were detected at low gas-phase concentrations with limits of detection ranging from 1.0 μg/m 3 to 6.3 μg/m 3 . Our results demonstrate a sensitivity enhancement for portable MS-instrumentation by using an ACI source, enabling direct, quantitative measurements of volatile organic compounds. Due to its high sensitivity, selectivity, low power consumption (<80 W) and weight (<13 kg), this instrumentation has the potential for direct on-site CWA detection as required by military or civil protection.

“…Phosphine (PH 3 ) is an inflammable and explosive gas with fish-or garlic-like odor, 33 highly dangerous on contact with air. By burning it produces a white dense fume of phosphorus pentoxide (P 2 O 5 ) which is a respiratory tract irritant due to the transformation in orthophosphoric acid (H 3 PO 4 ) reacting with water.…”

“Breaking Bad” Television Series Explained to Students

Objective: The classroom is an ideal environment to enhance the learning experience by the use of alternative media. In this paper we aimed to inspire a class discussion on the famous television series "Breaking bad", with the scope to analyze, interpreter and possibly explain all the chemical reactions and the bioactive toxic substances used during the episodes. Methods: We have found three main topics present in the series: i) methamphetamine preparation and its pharmacological effects, ii) explosives and inflammables, iii) poisons and other chemical substances mentioned in the series. Results: All these topics certainly are controversial but they are able to rise a prompt interest among the teenagers for topics such as organic chemistry, chirality, crystallography, purification of the substances, bioactivity, pharmacology and toxicology. However, the chemistry in the movie could be very misleading, overrated and imprecise, also the biological effects are artifact of the reality. Conclusion: We think that this paper could be used as guide to correctly understand TV series, prompting students to decide for themselves what is real or not. The drama characterized by the vivid images and sounds, as well as the occasional comic relief, promotes student engagement in the classroom more than a printed page.

“…1,2 There is also increased awareness concerning the vulnerability of civilian food and water supplies to deliberate contamination by chemical warfare agents (CWAs), typically assumed to target only military personnel and installations. Hence the urgent need for analytical technologies capable of detecting a wide variety of CWAs as well as their hydrolysis and degradation products in complex environments.…”
