Greenhouse Gas Analyzer

As greenhouse gas emissions from human activities increase, more and more greenhouse gases build up in the atmosphere, leading to warming the climate, and changing on-land and ocean weather patterns.

The ability to measure and track greenhouse gas emissions provides a global platform for understanding their role in climate change and also drafts a possible roadmap for changing human behavior to protect the planet.

Picarro is the leading provider of enhanced Cavity Ring-Down Spectroscopy (CRDS) analytical solutions, with more than 25 years in business, dedicated to measuring high-precision greenhouse gases and stable isotopes to advance environmental research, ensure regulatory compliance, and create safer workplaces and communities.

Picarro offers monitoring of Methane CH₄ (Methane), CO₂ (Carbon Dioxide), N₂O (Nitrous Oxide), CO (Carbon monoxide) [Including δ¹³C & δ¹⁸O] and NH₃ (Ammonia), etc.

The Picarro G2301 Gas Concentration Analyzer provides simultaneous and precise measurement of carbon dioxide (CO₂) and methane (CH₄) at parts-per-billion (ppb) level, and water (H₂O) vapor at parts-per-million (ppm) sensitivity with negligible drift for atmospheric science, air quality and emissions quantification.

Key Feature

Simultaneous and continuous measurement of three atmospheric trace gases

ppb sensitivity, precision, and accuracy with exceptionally low drift

Compliant with World Meteorological Organization (WMO) and Integrated Carbon Observation System (ICOS) international ambient atmospheric monitoring requirements

Water correction automatically reports dry gas mole fractions

Precision at 5 sec is < 70 ppb and < 25 ppb for CO₂ and 5 min is < 0.5 ppb and < 0.22 ppb for CH₄

Max. drift at standard temperature and pressure over 24 hr is < 120 ppb (CO₂) and < 1 ppb (CH₄)

The Picarro PI5310 Gas Concentration Analyzer is designed for high-precision measurements of nitrous oxide (N₂O) and carbon monoxide (CO). The PI5310 is ideal for long-term atmospheric measurements required by the most demanding greenhouse gas monitoring networks.

Key Feature

Simultaneous and continuous measurement of N₂O and CO

Excellent long-term stability and low drift of < 0.1 ppb

parts-per-trillion (ppt) measurements of N₂O and CO over a 1 to 1500 parts-per-billion (ppb) measurement range at < 5 sec intervals

Infrequent analyzer calibration and maintenance

Measure H₂O vapor and report dry mole fractions

Outstanding pressure and temperature stability

Meet the requirements of the World Meteorological Organization (WMO) greenhouse gas (GHG) compatibility goals and Integrated Carbon Observation System (ICOS) atmospheric stations specifications

Built on Linux operating system and includes features to enhance its robustness and ease of use

The Picarro PI2103 Gas Concentration Analyzer delivers ultra-precise and stable measurements of ammonia (NH₃) with a parts-per-trillion (ppt) lower limit of detection (LOD) and negligible drift. It is the ideal solution for urban and atmospheric air quality monitoring, studies of particulate matter formation, livestock emission quantification, vehicle emission quantification, indoor air quality and other applications. An additional carbon dioxide (CO₂) measurement can be used for surrogate validation, simplifying and replacing the need for complex calibration procedures requiring difficult-to-use standards.

Key Feature

Fast, continuous and real-time measurements

Superb sensitivity, precision and accuracy with virtually no drift

Month-long stability for infrequent calibration

Measurements of water for correction and CO₂ for validation

Precision at 5 min is 0.30 ppb

Maximum drift over one month is ±0.50 ppb at 25 °C and 760 Torr

The Picarro G2201-i Isotope Analyzer combines capabilities of two Picarro δ¹³C carbon isotope instruments for CO₂ and CH₄ into a single instrument. The dual-purpose analyzer brings simplicity and speed to research. Its small size and robustness make it easy to transport to the field, where immediate results allow researchers to change course on-the-fly and achieve optimal results from limited-time field campaigns.

Key Feature

Only field-deployable analyzer in market for simultaneous high-precision δ¹³C measurements of CO₂ and CH₄

Three measurement modes: CO₂ only, CH₄ only and CO₂ & CH₄ combined; in all modes, H₂O is measured

Excellent precision at a fraction of Isotope Ratio Mass Spectrometry (IRMS) operating cost due to less calibration, less maintenance and no consumables

Can be paired with a variety of peripherals to extend and expand functionality

Ecotech's Spectronus^TM analyzer offers simultaneous and real-time measurements of Methane CH₄ (Methane), N₂O (Nitrous Oxide), CO (Carbon monoxide) and CO₂ (Carbon Dioxide) [Including δ¹³C & δ¹⁸O].

Ecotech Spectronus^TM is the only high accuracy multispecies trace greenhouse gas and isotope analyser based on Fourier Transform Infrared (FTIR) spectroscopy. FTIR is a method that measures the absorption of infrared radiation by gases over a broad wavelength range.

As the only FTIR-spectroscopy-based in the globe analyzer that measure atmospheric multispecies greenhouse gases, trace gases and isotopes, Spectronus has garnered a reputation as the only one capable of meeting World Meteorological Organisation (WMO) standard for measured species.

In 2019, Spectronus was approved by the Integrated Carbon Observation System (ICOS) as a compliant and highly precise technique for measuring greenhouse gases within its network of greenhouse gases measuring stations across Europe.
