Food-grade CO2 analysis: new PTR-TOF 1000 ultra application

Real-time Quantification of Impurities in Food-Grade CO2 with PTR-MS

The modern food and beverage industry is not imaginable without food-grade carbon (CO2) dioxide. Its many uses include carbonation of beverages, and as packaging and cooling gas.

Pittcon 2017 poster: Real-time Quantification of Impurities in Food-Grade CO2 with PTR-MS.

In this study we investigate volatile organic impurities emerging from a food-grade certified (European standard E 290) carbon dioxide cylinder using a PTR-TOF 1000 ultra.

The PTR-TOF 1000 ultra is a compact PTR-TOFMS equipped with the ION-BOOSTER funnel technology. Its high sensitivity make the PTR-TOF 1000 ultra a perfect tool for applications where complex matrices have to be rapidly analyzed. One such example application is quality assurance in the food and flavor industry.

This very successful event organized by the University of Innsbruck every couple of years, attracted the community from all over the world for one week full of science and networking. Latest developments were showcased, results discussed and a bright outlook given for IONICON’s real-time trace gas analyzers. (more…)

There’s suspense in the air – detected with IONICON PTR-TOFMS

Scientists analysed the air in cinemas and discovered that every movie leaves a characteristic pattern of VOCs

Thomas Klüpfel installs a tube into the ventilation system of a cinema for PTR-TOFMS monitoring.

Researchers at the Max Planck Institute for Chemistry and the Johannes Gutenberg University in Mainz, Germany investigated how the composition of the air changed when an audience watched movies from different genres such as comedies like “The Secret Life of Walter Mitty” and “Buddy”, or fantasy movies like “The Hobbit” and the science-fiction thriller “The Hunger Games”. The scientists determined how the audience reacted to individual movies on a scene-by-scene basis. Using their analyses incl. PTR-TOFMS data, they were also able to reconstruct which scenes were playing at the time. (more…)

An international team coordinated by NASA has recently investigated air pollution over the Korean peninsula. Two of IONICON’s PTR-TOFMS instruments were used to monitor volatile organic compounds (VOCs) in real-time aboard NASA’s DC-8 Flying Laboratory. The data gathered by scientists from the University of Innsbruck and Korea’s National Institute of Environmental Research (NIER) will be used to improve satellite-based air quality monitoring over Korea.

VOC release from WPC: a new PTR-TOFMS application

Wood-plastic composites – replacing plastics with wood

Wood-plastic composites

In the quest for new alternatives for crude oil based materials such as plastics, WPCs (Wood-plastic composites) seem to be suitable materials, used in buildings and in the automobiles production. WPC are natural fiber composites with properties of both plastic and wood. It is estimated that the production of WPCs will experience an annual growth of 14% between 2014 and 2019 according to a study by the University of Eastern Finland.

In the study a new sort of additives to the WPC were investigated and the VOC release monitored with IONICON PTR-TOFMS (more…)

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.

The Proton Ionization Molecular Mass Spectrometry project “PIMMS”

A four year intersectoral and interdisciplinary training programme for Early Stage Researchers (ESRs) in analytical chemistry from 2012 to 2016

By early 2016, 15 young scientists will become available for the job market all of whom have unique portfolios of interdisciplinary and intersectoral technical, business and personal skills, making them highly employable within the growing knowledge-based job market in Europe. According to the project coordinator Dr. Chris Mayhew from the University of Birmingham, this is the major and most important outcome of the Marie Curie Initial Training Network “PIMMS”. We asked Chris to look back at PIMMS but also to tell us what’s coming up after this very successful ITN project.

“When I was preparing an application to the EU for training Early Stage Researchers in the technique of Proton Transfer Reaction Mass Spectrometry (PTR-MS) the quote Nothing tends so much to the advancement of knowledge as the application of a new instrument by Sir Humphrey Davy came to my mind. PTR-MS has truly advanced our understanding of bioscience, atmospheric chemistry and food sciences, to name but a few areas of application. It is a unique instrument and thus the resulting increase in the use of PTR-MS technology and the growth in its applications was outstripping the supply of suitably qualified scientists. (more…)
