According to the firm, different technologies are “extremely important” because VOCs (volatile organic compounds) mostly exist in a mixture of more than one organic compound, so measurements can be misleading “unless the individual compounds are speciated”.
AQE visitors will have the first opportunity in the UK to see the new FROG-4000 at work at the Quantitech stand. The device is a portable PID GC capable of analysing trace levels of individual VOCs in air, soil and water.
According to Quantitech, 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”.
Additionally, the firm will also demonstrate a 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 variety of chemical compounds in liquid, solid or gaseous samples, Quantitech said.
And, at 10am on Wednesday April 22, Quantitech will run a workshop in Room 3 of the AQE show 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.
Portable Gasmet FTIR analysers will also 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?’ at 11am on Thursday April 23 in Room 1.
