Reliably detect and monitor a broad range of gases
Ambient air quality monitoring solutions from Thermo Fisher Scientific leverage proven technologies, robust instrument designs and innovative data delivery systems to help ensure worker safety and regulatory compliance. Choose from a wide range of instruments that reliably measure air quality, low and high levels of criteria pollutants, various gases, and toxins according to your needs.
Ammonia (NH₃)
Ammonia (NH3) is a common toxicant released from a variety of sources including municipal waste and septic seepage, fertilizer runoff, and other natural processes that can cause a multitude of human and environmental health issues.
Ammonia is detrimental to human, animal, and aquatic life.
NO, NOₓ, and Nₜ modes of operation Our highly reliable ammonia analyzers utilize chemiluminescence technology for accurate, continuous ammonia monitoring.
Carbon Dioxide (CO₂)
Human activity such as burning fossil fuels (coal, natural gas, and oil), solid waste, trees, and other materials, as well as some chemical reactions can release large amounts of CO₂ into the air. As such, continuous monitoring of carbon dioxide has become critical to compliance with every increasing government regulation for industry.
The US Environmental Protection Agency (EPA) has taken regulatory actions to reduce greenhouse gas emissions.
Measuring carbon dioxide in emissions Our CO₂ analyzers employ reliable Nondispersive Infrared (NDIR) technology for long instrument life and advanced optical filters for accuracy.
Carbon Monoxide (CO)
CO is a colorless, odorless gas that is naturally occurring but can cause sickness and death when present in large concentrations in ambient air. The gas is most commonly released as a by-product of fossil fuel combustion in vehicles and machinery and is a highly regulated pollutant.
Carbon Monoxide (CO) is one of the six air pollutants controlled by EPA's National Ambient Air Quality Standards (NAAQS).
Detecting poisonous carbon monoxide Our CO analyzers use advanced gas filter correlation technology to detect and measure CO gas concentrations in ambient air.
Ethylene Oxide (C₂H₄O)
Ethylene oxide (EtO) is a versatile compound used for the sterilization of medical devices and in the manufacture of chemicals and consumer products, such as antifreeze and detergents. Due to its toxicity assessment, commercial sterilizers and chemical plants are required to measure EtO at very low levels to meet stringent government regulations.
Meet evolving government regulations and ensure worker safety.
Compliance with confidence Sensitive, real-time ambient air monitoring with full automation and integrated support to navigate regulatory compliance with ease.
Hydrogen Sulfide (H₂S)
Hydrogen sulfide is an extremely flammable and highly toxic gas. It is dangerous even at low concentrations and it occurs naturally in sewers, manure pits, well water, oil and gas wells, but is also used or produced in many manufacturing and industrial activities.
Hydrogen sulfide (H2S) poses a significant risk to worker safety in the oil and gas production, mining, paper production and wastewater treatment industries, among others.
Reliable data capture Hydrogen sulfide and sulfur dioxide analyzers utilize pulsed fluorescence technology for precise detection and concentration measurements of H₂S and S0₂ in the air.
iQ Series platform
Smart ambient air monitoring Built-in predictive diagnostics and preventive maintenance schedules identify problems before they occur.
Methane (CH₄) & Non-methane Hydrocarbon
Methane is emitted during the industrial production and transport of fossil fuels, livestock and agricultural activities. The regulations around methane gas release have recently been tightened in the US and are expected to continue to be scrutinized.
Methane (CH4) accounts for approximately 11% of all US greenhouse gas emissions from human activities.
Repeated collection and analysis Our analyzers make automated measurements of methane and non-methane hydrocarbons in the air using proven gas chromatography technology.
Nitrogen (N₂) and Nitrous Oxide Species (NO, NO₂, NOₓ NOᵧ)
Various nitrogen and nitrous oxide compounds (NO, NO2, NOY, NOx ) are emitted during agricultural, land use, industrial activities, fossil fuels combustion, solid waste management and the treatment of wastewater. As these gases can be harmful in various concentrations, careful and accurate monitoring is essential.
N2 accounts for ~7% of all US greenhouse gas emissions from human activities.
Predictive diagnostics Our analyzers utilize chemiluminescence technology to measure the amount of nitrogen, and nitrous oxides in the air from sub-ppb levels up to 1000ppb.
Ozone (O₃)
Ozone, also known as trioxygen, is an inorganic molecule visible as a pale blue gas. At high altitude, a layer of this gas provides protection against UV radiation from the sun. Terrestrially, it is used as a powerful industrial oxidant and, even at very low concentrations, is harmful to animals and humans.
Ozone (O3) when present at low altitude is a major air pollutant and can be seen as smog.
Proactive communications Our ozone analyzers utilize UV Photometric technology to reliably detect and monitor Ozone.
Sulfur Dioxide (SO₂)
Sulfur dioxide (SO₂) is produced in significant quantity through the burning of fossil fuels during the production of energy and other industrial processes, including industrial transportation. Sulfur dioxide can harm the human respiratory system and contribute to environmental pollution.
SO₂ is the sulfur oxide of most concern to regulatory agencies.
Highly precise Our sulfur dioxide analyzers measure up to 100ppm in ambient air using pulsed fluorescence technology.
Workplace hazardous air pollutants
Explore how our solutions can help you monitor hazardous air pollutants in your workplace. A disruptive new technique, called optically enhanced Fourier Transform Infrared (OE-FTIR) analysis, provides new capabilities in industrial gas analysis to meet such concerns.
Worker exposure to low-level toxins in ambient air is an increasing concern

Measuring hazardous air pollutants in the workplace Optically enhanced Fourier transform infrared (OE-FTIR) analysis provides enhanced gas detection sensitivity that rivals or exceeds that of traditional gas chromatography (GC). It also brings all the analytical advantages of traditional FTIR analysis such as real-time results, a wide dynamic range, and low maintenance and ownership costs.
Zero air supply and calibration
Zero air, or air that has been purified by removing pollutants such as NO, NO₂, O3, SO₂, CO, and hydrocarbons, is used to test and calibrate spanning ambient air analyzers during routine maintenance. Other analyzers can be calibrated using a multi-gas calibration device that performs zero, precision, Level 1 span checks, audits, and multi-point routines in accordance with US EPA requirements.
Ensuring optimal performance for your monitoring and analysis systems.
Personal device connectivity We offer zero air supply and multi-gas calibrators to keep your systems running at peak performance.
iQ Series instruments are built on an innovative platform that eliminates many of the challenges associated with integrating, operating, and maintaining ambient air monitoring systems. The platform supports Modbus, streaming and VNC protocols over serial and Ethernet as well as analog and digital I/O for easy integration into most data management systems.
The iQ Series platform provides greater control over instrument operation and makes data much more available and easier to use within your organization.
