2 Outline of the workshop: FTIR for emissions measurement Applications in ambient air Demonstration of a portable FTIR multigas analyser Q&A

3 Emissions measurements in two configurations

4 MCERTS certificate for transportable and fixed FTIR analysers issued in July 2003 To monitor emissions from processes certified under WID and LCPD 2003 certified for H 2 O, CO, NO, SO 2, HCl, NH added NO 2, N2O, CO 2 and Oxygen (by Oxitec 500E). Extended ranges for CO, NO, SO 2, HCl 2013 further changes - certificate pending

5 Gases and certified ranges Component Certification Range Additional Range Additional Range Total expanded Uncertainty Unit Uncertainty as % of ELV Maximum Allowed Uncertainty CO mg/m % (7.5%) NO mg/m % (15%) NO mg/m % (15%) N 2 O mg/m % (15%) SO mg/m % (15%) HCl mg/m % (30%) HF mg/m % (30%) NH mg/m % (30%) CO vol-% 5.00% (7.5%) H 2 O vol-% 6.20% (7.5%) O vol-% 2.40% (7.5%) * Total expanded uncertainty (U c ) is calculated according to EN ISO14956 as the combined uncertainty u c multiplied by a coverage factor of The uncertainty as % of ELV in parenthesis is the maximum uncertainty allowed for each gas in EN 15267, and the Gasmet CEM system meets these requirements for each tested gas.

6 Gases and vapours in the most common Gasmet emissions application library H 2 O Water Vapour CO 2 Carbon Dioxide CO Carbon Monoxide N 2 O Nitrous Oxide NO Nitric Oxide NO 2 Nitrogen Dioxide SO 2 Sulphur Dioxide NH 3 Ammonia HCl Hydrogen Chloride HF Hydrogen Fluoride CH 4 Methane C 2 H 4 Ethylene C 2 H 6 Ethane C 3 H 8 Propane C 6 H 14 Hexane HCHO Formaldehyde

7 Sample spectrum analysis areas HF H 2 O NO 2 CH 4 C 3 H 8 HCl HCHO CO, N 2 O NO CO 2, NH 3, C 2 H 4

8 Analysis of other hot and wet samples Emissions from Carbon Capture plant Demonstrate CO 2 reduction Trace amines in 100% CO 2 Fire Testing in accordance with ISO Gases include acrolein, phenol, formaldehyde and hydrogen bromide

9 Engine emissions measurements Testing abatement systems Researching new fuels Compliance monitoring

10 Applications in ambient air 2007 Gasmet launched the Dx4030 A portable, batterypowered FTIR suitable for measurements in the workplace and ambient environments

11 The Gasmet DX4030 No specialist training required for field use Regular calibration is not required No sample preparation required

13 EA sets up Response to Major Incidents Teams Each of the 9 teams equipped with two Dx4030 Near real-time data for target list Large library of gases for off-line analysis Also, Specific gas detectors for other gases High and low flow sampling systems

14 Latest Backpack analyser Dx4040 introduced in 2011 Pro version of Calcmet software enables identification of unknown compounds

15 A demonstration of toxic gas analysis

16 The Gasmet Cross interferences automatically compensated for in the analysis Measurements displayed in virtual real-time

17 The Gasmet Up to 25 gases measured simultaneously False positives highlighted during measurement Instrument status continuously logged and can be displayed at any time

18 The Gasmet Visual and audible warning of false positive detection All sample spectra saved for identification of unknowns, as a record of analysis or for use as evidence

19 Fumigation monitoring Water vapour, Carbon dioxide Carbon monoxide, Sulfuryl fluoride Phosphine, Ethylene dibromide Ethyl benzene, Toluene Methane, Nitrous oxide Ethylene, Acetic acid All gases measured simultaneously with results displayed in real-time. Up to 50 gases can be measured simultaneously Formaldehyde, Chloropicrin Benzene, Dichloromethane Carbon disulfide, Xylene Methyl bromide, Ammonia Hydrogen cyanide, Styrene, Isopropanol, Ethanol, MEK Additional gases can be added to library and saved samples can be reanalysed post sampling

20 Other applications include... HAZMAT/First Response Occupational hygiene Hospital applications Leak detection Vent exhausts Chemical warfare agents Cargo container fumigation Soil gas measurements Speciated VOCs from printing operations
