VOCs – why speciate?

24th February 2015


The Quantitech stands at AQE 2015 in Telford, the air quality and emissions show, will feature three different technologies for measuring individual organic compounds. This is extremely important because VOCs mostly exist in a mixture of more than one organic compound, so measurements can be misleading unless the individual compounds are speciated.

Firstly, AQE2015 will provide the first UK opportunity for potential users to see the new FROG-4000, a rugged, portable PID GC capable of analysing trace levels of individual VOCs in air, soil and water. This technology enables fast on-site analysis in a range of environmental, health and safety applications, which is a major benefit because samples containing volatiles are notoriously difficult to transport.

Secondly, Quantitech will demonstrate an innovative portable gas chromatograph toroidal ion trap mass spectrometer (GC-TMS). The TRIDION-9 combines a high speed GC with a miniaturised TMS in a lightweight, field-portable instrument, designed to rapidly detect an enormous variety of chemical compounds in liquid, solid or gaseous samples.

At the event, Quantitech will also be running a workshop outlining the identification and quantification of individual VOCs in applications such as contaminated land, pollution incidents, fenceline monitoring and environmental impact assessments. This workshop will include practical demonstrations of both the FROG-4000 and the TRIDION-9.

Finally, portable Gasmet FTIR analysers will be on display, offering simultaneous analysis of multiple compounds. The Gasmet product line includes online stack and process monitoring heated FTIR systems, portable heated FTIR analysers and an ambient FTIR gas analyser, the Gasmet DX4040. Application stories for these analysers will be detailed in a free Workshop entitled: ‘FTIR applications in this world and beyond?’.
