Passive sampler for monitoring atmospheric pollutants (VERAM)

Posted by Universitat de ValènciaResponsive · Innovative Products and Technologies · Spain

Summary of the technology

The most remarkable advantages provided by this technology are:
o Versatility, it is possible to sample a big number of pollutants using a single device containing a combination of solid phases.
o Greater adsorption capacity and high analytic sensitivity with smaller sampling time than market available devices.
o Rapidity and low cost of pollutant analysis. Thermal desorption and head space injection minimize sample handling, do not require the use of solvents and reduce the time of analysis.
o Cheap passive samplers with a fast and simple fabrication procedure.
o VERAM permits a multidirectional sampling differing from radial or one-way sampling devices with encapsulated solid phases.

Description of the tech for sale

Passive samplers let pollutants control in an environmental compartment, establishing their average concentration over the sampling time. Nevertheless, the currently available passive sampling devices are subordinated to the analysis of compounds with similar physical-chemical properties. Therefore, different samplers must be employed to carry out a multiple pollutant sampling. There is a need to improve sampler performance and achieve inexpensive and easy to use samplers. Researchers from University of Valencia have developed a fast, easy and versatile monitoring protocol for organic contaminants in air, based on the development of a new passive sampler named VERAM.

Specifications

This passive sampling device consists of a lay-flat low-density polyehytelene membrane filled with solid phases. Retained pollutants are directly determined by gas chromatography (GC) using head space injection (HS) after heating the sampling device. The great advantages include the absence of sample handling, the reduction of analysis time and the avoidance of the use of solvents. A mixture of different solid phases allows sample all the possible pollutants in the air or it is possible to select appropriated solid phases for a specific sampling of compounds as a function of their physical-chemical properties.

About Universitat de València

Public Agency from Spain

The University of Valencia, founded over five centuries ago by the Juries of Valencia, is a modern European public University, open to almost all branches of knowledge: social, economic and legal sciences, Basic experimental sciences, engineering and Tehcniques, health sciences, educational sciences and the humanities. More than 41,000 undergraduate students, 4,000 postgraduate students, 2,000 students from other universities all over the world, take classes taught by more than 4,000 professors, lectures and researchers at our campuses (more than 440.000 square meters) with the support of over 1,700 administration and service staff. Our university community is committed to being a university of reference: we are ranked 4º in Europe in receiving Erasmus students and 5ª in sending of students (Ranking Erasmus Mobility); It is fourth spanish university in research at the international level, ranking between 201 and 300, according to Shanghai Jiao Tong University Rankings. The University of Valencia is working in a wide range of investigative fields. The results of this activity are applied in a variety of productive sectors and social areas. Information of interest for businesses and public bodies about the Scientific and Technological Capacity of the University of Valencia is made available and offered for socioeconomic transfer through its Research Results Transfer Office (OTRI). The OTRI is a service that manages and assesses in the generation and transfer of University knowledge towards the industry, encouraging the University role as an active agent in the economic and social development; makes easier the access to the University of Valencia research facilities; manage the intellectual property of the research results produced in the University and carry out its valorisation for efficient transfer, and offers orientation of university research groups towards the needs of Business, promoting and guiding effective relationships for exchange of knowledge applied to the needs of social and industrial environment, making easier its information dissemination and transfer.
