ISIMS 2018 (Calgary, Canada)

22/Jul/2018

The 27th International Conference on Ion Mobility Spectrometry (ISIMS) took place in Calgary, Canada, from 22nd July to 27th July.

This conference was organized by the International Society for Ion Mobility Spectrometry. The aim of this society and their annual conferences is to promote the use of IMS. Ion Mobility Spectrometry is the lead technology for chemical agent detection and it is widely used in TOXI-triage. Some of our partners are members of the IMS Society board of directors.

This year TOXI-Triage related work was presented doubly:

TOXI-Triage at IABR Breath Summit 2018 (Maastricht)

17/Jun/2018

We are happy to announce that Ms. Dahlia Salman won the Poster Prize 2018 for ‘TOXI-Triage: breath analysis as a component in mass casualty triage’ awarded at the IABR Breath Summit 2018.

The International Association of Breath Research (IABR), organizes international conferences with the goal of providing an opportunity for researchers to meet and discuss important topics associated with breath chemical analysis, sensor instrumentation and biomarker detection and identification strategies.

Sprayed liquid-gas extraction of semi-volatile organophosphate Malathion from air and contaminated surfaces

Abstract

In this study, a new air sampling method termed sprayed liquid–gas extraction (SLGE) was developed for semi-volatile organic compounds. Water droplets with an average diameter of less than 10 μm were created, using a flow blurring nebulizer from distilled water and the gas-phase sample. This allowed the fast, simple and highly-efficient enrichment of trace levels of the widely used organophosphate insecticide malathion, which is also an accepted simulant for the potent nerve-agent VX.

Sprayed liquid-gas extraction in combination with ion mobility spectrometry: a novel approach for the fast determination of semi-volatile compounds in air and from contaminated surfaces

Abstract
We developed a fast, simple and highly-efficient enrichment procedure for trace levels of semi volatile organic compounds from air and surfaces and combined it with ion mobility spectrometry as field-deployable and rapid analytical technique. Our new technique, the sprayed liquid-gas extraction, was developed and optimized to allow the enrichment of semi volatile organic compounds. The air sample is pumped through a flow blurring nebulizer together with water. The sprayed liquid is collected and the organic compounds are transferred from the water phase to n-hexane via a miniscale liquid-liquid extraction. 50 μL of the n-hexane extract is applied to a fiber tape. After the n-hexane has evaporated, the fiber tape is transferred to the thermodesorber unit of a GDA-X ion mobility spectrometer (Airsense, Schwerin, Germany). The whole sampling and the sample preparation procedure takes no longer than 15 min and only requires 2.5 mL organic solvent. The method was optimized for Malathion, a widely used organophosphate insecticide and an accepted simulant for the nerve-agent, VX. Malathion provides defined ion mobility spectra in both, the positive and negative mode. The positive spectra show one major peak with a reduced mobility of 1.197 cm2 Vs−1 and an additional peak at 1.449 cm2 Vs−1 with lower intensity. A major product ion peak of 1.720 cm2 Vs−1 can be detected in negative mode together with an additional peak of low intensity at 1.403 cm2 Vs−1. The detection limit of the ion mobility spectrometer is approximately 20 ng absolute.

Robotic and autonomous countermeasures

Security and defence discussions are now filled with speculation about robot weapons and artificial intelligence (AI). The problem is, security cannot be built on robotic weapons, autonomous systems or AI alone. Autonomous systems are more like operating platforms and firing systems than weapons per se. For example, electro-optical weapons, firearms, missiles, and nuclear weapons are defined by their impact. Robotised features simply increase that impact.

1st DGKM-CBRN Forum (Berlin)

5/May/2018

Christoph Amelunxen from the University of Paderborn presented "TOXI-triage - Introduction to an EU-Development Project" at the 1st DGKM-CBRN Forum on 5th May in Berlin, Germany.

The1st DGKM-CBRN Forum focused on medical mission management and medical care in a mass casualty of CBRN-contaminated patients.
The aim of this forum is to provide, via selected scientific contributions and practical demonstrations, with a platform for professional exchange and networking opportunities on the topic of CBRN-related medical protection.
