AQE workshop 14 March 2013


Outline of the workshop:

• FTIR for emissions measurement

• Applications in ambient air

• Demonstration of a portable FTIR multigasanalyser

• Q&A



Emissions measurements in twoconfigurations



• To monitor emissions from processes certified underWID and LCPD

• 2003 certified for H2O, CO, NO, SO2, HCl, NH3

• 2008 added NO2, N2O, CO2 and Oxygen (by Oxitec500E). Extended ranges for CO, NO, SO2, HCl

• 2013 further changes - certificate pending

MCERTS certificate for transportable andfixed FTIR analysers issued in July 2003

Applications in ambient air

• 2007 Gasmet launchedthe Dx4030

• A portable, battery-powered FTIR suitablefor measurements inthe workplace andambient environments



• No specialist trainingrequired for field use

• Regular calibrationis not required

• No samplepreparation required

Latest Backpack analyser

• Dx4040 introduced in2011

• Pro version of Calcmetsoftware enablesidentification ofunknown compounds



A demonstration of “toxic” gas analysis



• Cross interferencesautomaticallycompensated forin the analysis

• Measurementsdisplayed invirtual real-time

The Gasmet



• Instrument statuscontinuouslylogged and can bedisplayed at anytime

The Gasmet


• Up to 25 gasesmeasuredsimultaneously

• False positiveshighlighted duringmeasurement


• Visual and audible warningof false positive detection

• All sample spectra saved foridentification of unknowns,as a record of analysis or foruse as evidence

Fumigationmonitoring

Water vapour, Carbon dioxideCarbon monoxide, Sulfuryl fluoridePhosphine, Ethylene dibromideEthyl benzene, TolueneMethane, Nitrous oxideEthylene, Acetic acid

Formaldehyde, ChloropicrinBenzene, DichloromethaneCarbon disulfide, XyleneMethyl bromide, AmmoniaHydrogen cyanide, Styrene,Isopropanol, Ethanol, MEK

All gases measured simultaneously with results displayed inreal-time. Up to 50 gases can be measured simultaneously

Additional gases can be added to library and saved samples can be re-analysed post sampling
