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…)

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 for indoor air quality monitoring

A new review article discusses important applications of IONICON PTR-MS systems in indoor air quality monitoring.

Many sources of airborne contamination e.g. VOCs (volatile organic compounds) influence on the quality of indoor air. These substances are emitted by household products, electronics such as computers, printers or TVs,  construction materials, wall-paints, carpets, and furniture.  Many of which are known to affect human health or at least to cause unpleasant odors. They can be present in high concentrations due to insufficient ventilation inside closed spaces such as e.g. buildings, offices etc. but also cars and aircraft cabins. Chemical contamination of indoor air is a contributing factor to the so called “Sick Building Syndrome“.

IONICON PTR-MS is an excellent tool for assessing the concentration of indoor air VOCs, providing real-time quantitative results from very low levels (sub-pptv) to high concentrations (ppmv and above).

A new article by S. Schripp et al. discusses various scenarios, sources of contamination and their impact on the indoor air quality. The team of Fraunhofer WKI, Braunschweig, Germany, and IONICON described five applications of PTR-MS in Indoor Air:

IONICON PTR-TOF 8000 helps measuring air quality onboard Airbus aircraft

For Airbus, cabin air quality is the key to a comfortable flight – IONICON PTR-MS technology helps the aircraft manufacturer analyzing the air.

On aircraft, cabin air quality contributes significantly to the comfort and well being of passengers and crews alike. Commercial aircraft operate primarily in the troposphere and lower stratosphere, which is an environment hostile to life. A sophisticated aircraft environmental control system ensures that our journey onboard aircraft usually is a comfortable experience despite outside conditions of -50°C, high ozone concentrations and only 1/5th of the ambient pressure on the earth’s surface. Outside air which is usually very clean, particularly during flight, is conveyed into the pressurized fuselage and approximately the same amount is discarded overboard by the environmental control system. The entire cabin air is exchanged with outside air every three minutes.

In an article in the Airbus / FAST magazine #50 (August 2012) Dr. Andreas Bezold (Airbus Operations GmbH) explains details of cabin air quality, the aircraft environmental control system and measurement campaigns involving an IONICON PTR-TOF 8000 instrument providing further insights:

New PTR-MS “indoor air quality” application note

VOC emissions in our homes, offices or cars – an exemplary study of commercial air fresheners

Volatile Organic Compouns (VOCs) are chemicals that vaporize at room temperature and many of which are known to be harmful to our health or have a bad smell. Nearly every commercial product we use emits VOCs, some of them on purpose (e.g. air fresheners) but a lot of them unintentionally (e.g. furniture like carpets or paints).

Learn more about indoor air quality and VOCs at the US EPA’s website.

Regulations exist to keep the level of VOC emissions low as many people react irritated to some of the substances. The so called “Sick Building Syndrome” is a situation where according to the US EPA “…Building occupants complain of symptoms associated with acute discomfort…”.  “Chemical contaminants from indoor sources” is cited as one of the “contributing factors to sick building syndrom”.

Learn more about the Sick Building Syndrome at the US EPA’s website (sources from above).

IONICON PTR-MS is often used for real-time quantification of trace VOCs in our outdoor environment, but also indoors. PTR-MS allows for straightforward, immediate analysis of air without any complicate sample preparation providing real-time results as mass spectra. Therefore many customers use PTR-MS for applications including:

Safety and Protection of built Infrastructure to Resist Integral Threats

Terrorist attacks by bombing or CBR (Chemical, Biological and Radiological) are threats with a low likelihood but with extremely high impact.
There is strong need to protect critical infrastructures and utilities (malls, governmental buildings and embassies), train and subway stations against being damaged, destroyed or disrupted by deliberate acts of terrorism, criminal activity and malicious behaviour.

The overall aim of the SPIRIT project is to provide the technology and know-how for the protection of buildings and people against terrorist treat and to minimize the consequences of a terrorist attack in terms of number of casualties/injuries, damage and loss of functionality and services.
