Requirements for monitoring emissions to air are governed by EU/UK legislation and are implemented in the form of a permit by the Environment Agency or local authority. The Dr Foedisch muti-component gas analysers continuously extract a gas sample from the exhaust stream via a stack probe into the analyser cabinet.
Both hot and cold gas systems are available, please contact us to discuss which system best suits your requirements.
The exhaust gas from combustion engines is a complex mixture of gases and particulate matter. The composition of the gas may change rapidly. Multicomponent analysis of exhaust gases can be performed with a Gasmet™ FTIR Gas Analyzer with a response time (T90) of one second. The winning combination is the result using of a small volume gas sample cell, a powerful sample pump and a fast detector with liquid nitrogen cooling. The analyzer, sampling system and computer can be assembled on a cart for use in a...

The process control of a sulphuric acid plant needs good and reliable detection of gas phase sulphur dioxide (SO2). To measure SO2 is a challenge due to the corrosive environment and high concentration of SO2. Several places in the process needs to be monitored and to transport the sample gas is difficult. A large dynamic range is needed as the SO2 concentration can vary between 15% volume and a few mg/m3. Most systems installed need a lot of maintenance, sometimes as often as every day.
Ormantine offers a wide range of products and services to meet the array of different needs that arise in the oil and gas industries. Volatile Organic Compounds (VOCs), benzene, and other compounds are released during drilling, hydraulic fracturing (fracking) and other extraction procedures. Monitor NOx emissions from heavy duty equipment, particulate matter, and ground level ozone, the formation of which is contributed to by VOCs from processing, transportation, and storage of oil and gas.
The process control of a CO2 capture plant needs good and reliable detection of gas phase NH3 and CO2. Measuring NH3 is a challenge due to the corrosive environment and high concentrations of NH3. Several places in the process needs to be monitored and to transport the sample is difficult. A large dynamic range is needed as the NH3 concentration can vary between 15% volume and a few mg/m3.
Finding efficient ways to generate, deliver and consume energy resources while reducing pollution is an ongoing quest for the Energy & Utility Industries. HI-Q has developed instrumentation geared toward monitoring emissions and the dispersal of pollutants from power plants and industrial facilities. HI-Q base-line & stack sampling equipment has been used in studies to identify and track the spread of pollutants around the globe.
The Series 8900 Hydrogen Sulfide and Carbon Disulfide Analyzer provides direct measurement of H2S and CS2 in ambient air. This instrument is utilized for continuous emission monitoring. The Series 8900 H2S and CS2 Analyzer employs a Photoionization detector (PID) as the sensing element. A dual column configuration with timed backflush to vent is used to strip off moisture and heavier hydrocarbons. A pre-cut column is used in series with the analytical column. At sample injection a fixed volume of sample is...
A key issue in the measurement of the products of combustion in Cement and Lime industries is the high levels of particulates. The Procal 2000 in situ analyser`s heated probe option is especially suited to this industry as it efficiently deals with variations in process temperature, keeping the probe above the sample dew point and safe from corrosive condensate.

The industrial chimney's emissions of Volatile Organic Compounds (VOCs) are becoming issues of global importance and to have an accurate knowledge about how to test VOC turns into a strategic issue. VOC emissions are quantified and monitored according to standard EN 12619, using FID analyser which uses hydrogen and other reference gases in pressurized cylinder. Operators must then approach the sampling point, often placed several meters from the ground, climbing chimneys of industrial settlements with...
Cerex Multi-Gas Open Path Analyzers are available in both FTIR and UVDOAS technologies to meet specific requirements for perimeter ambient air quality monitoring, leak detection, fugitive emissions monitoring and ambient air quality monitoring. Cerex multi-gas analyzers offer significant advantages over single gas analyzer arrays, electro-chemical sensor arrays and time integrated air sampling hardware
Many of the air quality analyses can be performed with standard laboratory consumables, such as traditional filter papers. However, some analyses require materials with specific features, for example filters with low metal levels.
Common air monitoring applications include:
Air quality testing of ambient environment and emissions. Includes particulate monitoring methods such as PM2.5 and PM10, and chemical analysis such as heavy metals determination.
Asbestos sampling and analysis
Primary aluminium smelting generates large amounts of hydrogen fluoride gas (HF). Worker safety and ambient air quality concerns require that HF be monitored at several locations in smelters. Traditionally, a variety of chemical sampling methods have been used for HF monitoring in and around smelters. However, these methods are labour intensive and require ongoing maintenance and consumables. During the past decade, laser based HF analyzers have been replacing the traditional methods. Laser analyzers are compact,...
Most sources of fugitive emissions are from multiple points rather than single point sources. So, open path area or perimeter monitoring provides more meaningful fugitive emissions data than an array of point sensors or a program of grab sampling. Point measurements may underestimate emissions because of missing locations with high gas concentrations, or conversely overestimate because they are located in areas of high concentrations. Grab sampling programs typically check only a small percentage of potential...
CFCs are used in the manufacture of insecticides and herbicides and the environmental impact of their use must be well controlled. The treatment of CFC emissions to reduce the emissions in the intermediary steps of production needs to be monitored with 100% efficiency. Protea’s portable CFC analysers and continuous CFC monitoring systems can be configured with various sample inlets and analytical modelling to enable multi-samples to be measured on the one system.
