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:


PTR-MS for the sensitive and rapid real-time detection of solid high explosives in air and water

A new article in ABC demonstrates the capabilities of detecting explosives in air and water with IONICON DAI-PTR-MS

IONICON scientists successfully demonstrate  the DAI (direct aqueous injection) system’s capabilities to detect explosives in water. The IONICON DAI system is currently in development and allows for injection of liquids and analysis of which in IONICON PTR-MS instruments.

PTR-MS is known for its low real-time detection limit for trace VOCs in air and the DAI system will be used to extend the range of possible PTR-MS applications to the liquid phase.


Relying on recent developments in proton transfer reaction mass spectrometry (PTR-MS), we demonstrate here the capability of detecting solid explosives in air and in water in real time.


58th ASMS preview

May 23 – 27, Salt Lake City, Utah

The 58th ASMS Conference on Mass Spectrometry and Allied Topics will be held in about one month’s time hence it’s a good opportunity to point your interest to this event and our related activities.

The American Society for Mass Spectrometry expects the attendance of of 7,000 scientists giving 3,000 presentations as talks and posters. The poster/exhibit hall will feature over 650 different posters each day and 184 exhibit booths, providing a broad array of science and technology.

We will be there too continuing our support of the ASMS as a corporate member that we have been over the last couple of years.

If you plan to visit the annual ASMS conference in Salt Lake City, drop by our booth No. 43!

In the poster/exhibit hall you will also find a corporate poster as well as a scientific poster. We’ll present our latest invention, DAI (direct aqueous injection) for PTR-MS. The poster’s title is:

Analyzing liquids via direct injection proton-transfer-reaction mass spectrometry (PTR-MS).

Session: Instrumentation: New Concepts I (671): Wednesday, May 26, 2010.
