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.
Proton-transfer-reaction mass-spectrometry (PTR-MS) is an analytical technique that offers a broad variety of advantages such as response times down to 100 ms, detection limits in the ppqv (parts-per-quadrillion) range, real-time quantification, mass resolutions up to 8.000 m/Δm (in case a TOF based instrument is used), etc. However, except for a few attempts with membrane inlet systems in the past, PTR-MS is limited to gas phase samples, i.e. thus in case of liquids to headspace analysis. Here we present a novel inlet system for PTR-MS that allows for direct aqueous injection (DAI) of liquid samples. As this DAI system is e.g. ideal for water pollution studies, we show here first data about trinitrotoluene and dinitrotoluene contamination of water.

I will personally be attending ASMS and would be glad to meet you in Salt Lake City.
