NH4+ Ionization for Explosives and CWA Detection

Crucial application benefits from fast switching NH4+ ionization

The proprietary and IONICON exclusive method of producing NH4+ solely from H2O vapor and N2 in the established hollow cathode ion source, without the need of any ammonia (PCT application submitted) has many advantages.

Today we would like to introduce a promising application field where NH4+ is the ideal reagent ion. The unambiguous and highly sensitive detection of explosives as well as chemical warfare agents.

TATP real-time detection

Analyzing the headspace of some µg of the infamous explosive TATP with NH4+ reagent ions boosts the TATP.H+ signal by a factor of 20 compared to the H3O+ mode, because of suppressed fragmentation. Additionally the cluster TATP.NH4+ is formed at an even higher abundance. Thus, by using TATP.NH4+ as an additional detection marker, also the selectivity is considerably improved in “NH4+ mode”.

Live tests and real-time detection of CWAs

The nine most important CWAs (including Sarin, Tabun, Soman, VX, Lewisite, Cyclosarin, Nitrogen mustard and Sulfur mustard) have been investigated at a facility specialized and licensed for CWA handling.  (more…)

SRI-TOFMS: Rapid Analysis of New Psychoactive Substances Blends

Identification of active ingredients in seconds without sample preparation

A popular NPS blend marketed as “synthacaine” on the internet.

Following up our recent research on explosives, chemical warfare agents, toxic industrial compounds and illicit drugs detection, we are currently focusing on the analysis of New Psychoactive Substances (NPS) utilizing state-of-the-art IONICON PTR-TOF 8000 instruments equipped with SRI capability. NPS, or “designer drugs”, “legal highs” and “research chemicals”, as they are often called, are chemicals with psychoactive effects either similar to illicit drugs or genuine on their own. However, the relevant legislation varies from country to country and NPS are in fact readily available over the Internet.

Detection of Toxic Industrial Chemicals (TICs) with IONICON PTR-MS

Application case study and article in press: Isocyanates and Polychlorinated Biphenyls real-time detection using PTR-MS

Isocyanates are highly reactive species widely used in industry. They can cause irritation of the eyes, trigger asthma, etc. Polychlorinated biphenyls (PCBs) were widely used in electrical equipment like capacitors and transformers in the last century and are still present in the environment today. PCBs are known to cause cancer and to affect the immune, reproductive, nervous and endocrine systems.

Therefore, there is a need for a simple, rapid and reliable analytical method for the detection of traces of isocyanates and of PCBs. IONICON PTR-MS technology seems to be an ideal method for rapid screening for TICs which we demonstrated in a recently published article:

New Overview Article on IONICON PTR-MS and its Applications in “American Laboratory”

Technical Advances in Proton Transfer Reaction-Mass Spectrometry and New Fields of Application.

In 1998 IONICON was founded and we were able to sell the first commercial instrument. Since then, after years of dedicated research, passionate development and intensively working together with our partners and customers, we sold more than 200 units. Learn more on the recent advances of the PTR-MS technology, our products and their applications in an article with the title Technical Advances in Proton Transfer Reaction-Mass Spectrometry and New Fields of Application, published in American Laboratory (September 01, 2011) being available online.

IONICON at 6th Future Security, Security Research Conference

IONICON science manager, Dr. Philipp Sulzer will co-chair the session A3 Detection of hazardous Material and give a lecture.

Terrorism, organized crime and sabotage, but also natural disasters and technological accidents can cause serious damage and disruption with long-lasting consequences for economies and the quality of life.

The 6th Future Security, Security Research Conference will take place 5. -7. September 2011 in Berlin, Germany and has the aim to bring together the decision makers in politics, industry and finance with scientists working on leading edge and innovative concepts, sensors or systems for civil security.

Philipp Sulzer will chair the session Detection of Hazardous Material on Tuesday September 6 from 9:00 to 10:20 and give a lecture with the title: Detection and Identification of illicit and Hazardous Substances with Proton-Transfer-Reaction Mass Spectrometry (PTR-MS).
