Truck mounted Thermo Fisher AAQMS

Stationary/ Point Source Emission

​AETS uses local as well as intenrational methods/ guidelines to measure the following:

  • Stack emissions monitoring​

    • Dioxins and furans (USEPA Method 23)

    • Metals (USEPA Method 29)

    • PM (USEPA Method 1 to 5)

    • Halides: HCl, HF, HBr, Cl2, Br2 (USEPA Method 26a)

    • O2,CO,NO/NOx,NO2,SO2, & VOC Sensors NDIR Bench (CO2,CxHy,CO high)

    • Pollution control equipment

      • Bag filters

      • Scrubbers

      • Efficiency

Air Quality Monitoring

We carry out a range of Air Quality Monitoring services.These include the following:

  • Air quality monitoring of pollutants using mobile Ambient Air Quality Monitoring Station (AAQMS)

  • Isokinetic sampling using APEX autokinetic sampler

  • Odour measurements using an Olfactometer

  • Dust surveys

  • Long-term pollutant monitoring using Diffusion Tubes

  • Emissions from vehicles and DG sets

  • Noise measurements

  • Personal pollution monitoring for occupational health & safety

  • CEMS verification

  • Radiation surveys

  • Vibration surveys from blasting

  • Consulting on air pollution reduction measures

  • Analysis of metals in stacks

  • Air Pollution Modelling

  • Light (LUX) and oxygen measurements

  • High Volume air sampler

    • SPM

    • PM10

​

We compare air quality against US EPA National Ambient Air Quality Standards (NAAQS) or any other standard required by our clients. 

​

Our Flue gas analyzer is designed especially for point source emission measurements to carrying out adjustments as well as making long-term measurements and inspections on boilers, furnaces, burners and heating equipment.

​

The  Flue Gas Analyser is equipped with multi-probes to measure stack emissions in compliance with USEPA Method 2 & USEPA Method 4 for gases and USEPA Method 5 for  particulate matter. 

​

In addition to this reference methods (RMs) 1&3 are employed to obtain flow and molecular weight from oxygen and carbon dioxide measurements using a Portable Multi-Gas Stack Analyzer.  During the sampling, all sample containers are properly marked and stored until performing the analysis at laboratory.  Final analysis is carried out by ALSAFA ETS.
