Mobile Continuous Emissions Monitoring System

Our CEMS certification and auditing services include Relative Accuracy Test Audits (RATA) and Cylinder Gas Audits (CGA). RATAs are conducted using a mobile CEMS trailer equipped with pollutant analyzers, sample extractive equipment and data acquisitions systems. Audit results are calculated and reported on-site to ensure a timely response to regulatory compliance requirements. RATAs are typically performed on CEMS parameters NOx, SO2, CO, TRS, and O2.

Our mobile Continuous Emissions Monitoring System (CEMS) is uniquely positioned to deliver full on-site CEMS capabilities to meet any of your requirements. The system can be utilized to ensure regulatory compliance, pollution control, system performance evaluations and system optimization. Regulatory compliance monitoring such as RATAs or Manual Stack Surveys are the most common application.

Our mobile CEMS personnel use the following sample collection and analytical techniques:

• Chemiluminescence
• Photoluminescence
• Gas Chromatography (PID,FID, TCD )
• Non-Dispersive Infrared (NDIR)Paramagnetic
• Ion Chromatography
• GC/MS
• High Resolution MS
• Inductively Coupled Plasma (ICP)

Test Methods

Industry regulations dictate test methods to be followed when sampling and analyzing for emission pollutants.

The typical test methods utilized by our Air Quality Monitoring Division include the following:

• US EPA
• Alberta Stack Sampling Code (ASSC)
• Manual Methods for Chemical Analysis of Atmospheric Pollutants (MMCAAP)
• Environment Canada
• American Society for Testing and Materials (ASTM)
• National Institute for Occupational Safety and Health  (NIOSH)

Codes of Practice

Regulations come from the BC Field Sampling Guide, AENV CEMS Code, CCME, Air Monitoring Directives (AMDs) and provincial and federal codes of practice. These codes of practice cover:

• CCME Turbine Emission testing
• Asphalt Plant Emission testing
• Small Incinerator Code of Practice
• Ethylene Oxide Destruction Efficiency testing
• Coal Fired Power Plant Code of Practice
• Forage Drying Facility Code of Practice

Passive Air Quality Monitoring 

Passive Air Quality Samplers (PAQS) provide a cost-effective method for collecting air quality data over a large geographic area. This system does not require power, data loggers or pumps, making it an excellent tool for sampling in any region, no matter how remote. AGAT Laboratories is accredited under ISO 17025 by the Standards Council of Canada (SCC) and our PAQS have been field-validated to meet the requirements of regulatory air quality monitoring programs.

The main advantage to this simple but effective sampling device is the ease in which they can be deployed and operated. The PAQS are housed within a protective rain shelter which holds up to 4 samplers, and can be mounted to a post, fence, or other stable structure in the area easily and quickly. The shelter hold the PAQS in a downward position and ensures there is no active movement of air through the sample.

How Does the Sampler Work?

PAQS operate on the principles of adsorption and permeation, physically binding to the specific compounds that are being targeted. Air pollutants will passively diffuse through a semi-permeable membrane and then collect on a filter that has been chemically treated to adsorb those targeted compounds. After being exposed for a specific period of time, the sampler is analyzed in the laboratory to determine the amount of the targeted compound collected.

Pollutants of interest for passive air monitoring include Sulphur Dioxide (SO2), Hydrogen Sulphide (H2S), Nitrogen Dioxide (NO2), Ozone (O3), Ammonia (NH3), and Volatile Organic Compounds (VOCs).

Applications

Passive Air Monitoring Samplers are routinely used to meet regulatory air monitoring requirements in Canada, to determine baseline readings prior to facility startup, or as a means to monitor a large geographic area where continuous air monitoring is cost-prohibitive.

Results are used to establish long-term trending of pollutants of interest and can be operated independently from or as part of a larger air monitoring program, which may also include continuous ambient air monitoring.

Continuous Ambient Air Monitoring

Our Ambient Air Monitoring team specializes in providing a full suite of services to clients requiring continuous air quality monitoring, from rental or purchase of custom-built stations, to meteorological monitoring, data acquisition and regulatory compliance reporting (monthly and annual). We work closely with clients to meet the goals of their particular air monitoring project. Our service offerings include:

Integrative Air Monitoring

We offer various integrated sampling programs including SUMMA canisters and filter-based collection,drawing air through filters and absorbents for both indoor and outdoor monitoring as well as soil vapor testing.

Applications

• Environmental monitoring
• Odour profiling/complaints
• Industrial hygiene
• Emissions studies
• Landfills
• Site characterization
• Wastewater treatment plants
• Remediation

Samplers and Capabilities

We use specialized sampling techniques that align with US EPA methods such as:

Summa Canisters

AGAT Laboratories offers Silonite Canisters, the latest in SUMMA testing technology, for the collection of indoor, ambient and stationary air sources and soil vapour. These canisters are used for volatile organic determination in ambient indoor air by EPA TO-14A/15A- Canister Sampling.

Silonite technology increases the integrity of samples by preventing degradation by exposure to sunlight and the permeation of VOCs through the vessel walls. This allows easy shipping and storage over longer periods of time.

Maybe the black background can be removed? The image comes from the SUMMA Analytical Capabilities brochure. I like the current image on the page and that should be kept as well.

Meteorological Monitoring

We provide stand-alone meteorological monitoring stations that can be solar-powered, complete with data logging and real-time polling capabilities. Instrumentation measuring wind speed and direction sits atop a 10 meter tower, while lower down additional instrumentation can be mounted for ambient temperature, barometric pressure, etc. Meteorological data is transmitted through the LTE network and polled to our WebAIR data portal for 24/7 accessibility. 

Fugitive Emissions

AGAT Laboratories offers Fugitive Emissions field services to assist clients in meeting regulations for emissions monitoring. Our specially-trained and certified technicians.

Using our infra-red GF320 FLIR cameras and QL320 Quantitative Optical Gas Imaging instrumentation, we can assist preventative maintenance efforts and detect leaks in real-time in all manner of pipes and connections, at a wide variety of facilities. Hundreds of components can be scanned in one shift, identifying areas for repair to reduce emissions, increase workplace safety, and improve your bottom line. AGAT Laboratories’ field specialists can record detailed leak information, pictures and videos directly to an online platform, complete with GPS data, helping clients to track and pinpoint leaks immediately and safely. Following identification of the leak, we can accurately quantify the leak rate by loading the video captured by the FLIR camera to the Providence Photonics QL320 Quantitative Optical Gas Imaging device.
