Join us for our LIVE demo at Pittcon 2016!

“The Air We Breathe In & Out at Pittcon”

In less than two weeks, Pittcon is going to open its gates for us.
New in this year are pre-scheduled live demos.
Check out the air on the show floor with us!Pittcon_live-demo_ionicon_webTuesday March 8, 2016. 4:00 pm, demo area 1 (booth #2565).

PTR-MS breath test shows potential for detecting liver disease

Researchers at the University of Birmingham have published results that suggest a non-invasive breath test for liver disease using an IONICON PTR-MS. Elevated levels of limonene in patients have been found to be indicative of a diseased liver.

Especially in the UK liver disease has risen sharply over the past few decades and is the third biggest cause of premature mortality. Patients do not often present with symptoms until the disease is advanced. Even then diagnosis is difficult and the symptoms are often general and can be mistaken for other pathologies.

Breath gas analysis is a non-invasive method to collect information on the state of an individual by monitoring the concentration of the volatile organic compounds (VOCs) present in the exhaled breath, which are directly correlate to their concentrations in blood.

Live demonstrations at Pittcon 2013 – a huge interest in IONICON PTR-MS

Visitors were curious to test their breath in real-time and get some insight on the air they inhale at the show floor

Pittcon 2013 took place in Philadelphia for the very first time and attracted  more than 18,000 attendees, 1,011 exhibiting companies from 28 countries and of course also us. We at IONICON showcased our most recent products such as the Liquid Calibration Unit (LCU), the IONIMED BET-med breath sampling inlet, and a full range of  Trace Gas Analyzers based on PTR-MS and SRI-MS technology.

We feel that a live demonstration of our PTR-MS instruments is the best way to show their outstanding capabilities. Many visitors were attracted by the chance of doing real-time breath analysis and experienced the benefits of a quantitative and fast response, having a PTR-QMS 300 instrument connected to a special BET-med breath sampling inlet.

Ionimed’s medical research on coverpage

Cover Page Gyn-Activ

As a partner in the research framework ONCOTYROL (Center for personalized cancer medicine), Ionimed Analytik has conducted clinical breath gas analysis to investigate new ways for breast cancer screening. This work has now been picked by the Austrian journal GYN-AKTIV as their cover story for issue 6/2012 (in german). In this project Ionimed has employed an Ionicon PTR-TOF 8000 for the analysis of breath samples from more than 200 patients and controls.

Find the story in GYN-AKTIV 6/2012 (in German): pdf

Ionimed Analytik is a partner in the EU project LCAOS

The focus of EU project LCAOS is the development of nano-sensors for medical breath analysis. Ionimed provides PTR-MS technology to complement the sensor information and develops a novel calibration device for sensor characterization.

IONICON presents N.A.S.E. – Nosespace Air Sampling Extension to PTR-MS

IONICON N.A.S.E. is a heated device for the collection of nosespace air and direct introduction into the inlet of a PTR-MS system.

We listened to the feedback from our customers and developed a device for further improving our response time optimized heated PEEK inlet system, especially for PTR-MS users in food, flavor & fragrance science.

Substances of interest such as e.g. Vanillin are often very “sticky” and condensate on cold spots of an inlet system. Therefore we have engineered a solution overcome this issue.

PTR-MS compared to SIFT-MS, APCI and MS-e-noses

A new review article in Trends in Analytical Chemistry discusses direct-injection mass spectrometry for VOC analysis.

F. Biasioli, C. Yeretzian, T. D. Märk, J. Dewulf and H. Van Langenhove wrote an interesting review with the title “Direct-injection mass spectrometry adds the time dimension to (B)VOC analysis” that was recently published in Trends in Analytical Chemistry 30 (7) (2011).

We at IONICON are often asked what actually the differences and in our case, the benefits of the PTR-MS technology compared to other, similar methods are. Not only a technical comparison is of interest but also feedback from studies in the field covering various applications is in high demand by people contacting us.

For me the advantages of PTR-MS are obvious and I also know which position our technology and products have in the market, but of course it is more credible if an article in a peer-reviewed journal has such a comparison as topic and gives the reader a chance to follow a well grounded debate.
The synopsis of this article with regards to PTR-MS and my conclusion, I would summarize as follows only mentioning the most intriguing arguments:
