CO2/H2O Analysis

Although CO2/H2O analysis tends to focus on atmospheric CO2 and global climate change, there are many other applications that require CO2 and water vapor measurements. These include research, industrial, and management applications such as volcano monitoring, plant productivity research, greenhouse monitoring, in-door air quality monitoring, industrial process control, and others.


Common research fields that use CO2/H2O analysis are:

  • Atmospheric monitoring
  • Eddy covariance flux measurements
  • pCO2/DIC measurements
  • Photosynthesis measurements
  • Soil CO2/H2O exchange
  • Evaporation/transpiration
  • Respiration

Common management and industrial processes that use CO2/H2O analysis:

  • Industrial process control
  • Indoor air quality management
  • Food quality control
  • Fruit and vegetable storage
  • Greenhouse control systems
  • CO2 Sequestration and storage
  • Semiconductor industry

As the lists above indicate, CO2/H2O analysis is used in a large variety of applications. No single analyzer fits the diverse needs of this variety of applications.

When considering an analyzer for your application, some things to consider include power requirements, response time, accuracy requirements, precision, and whether open or closed path is needed. In addition, some applications require the use of automated communications protocols and on-board data storage capacity. By addressing the needs of your application, you can choose the analyzer that is best suited for your application.
