Respirometry Defined

A close-up view of a Respirometer

When we think of the environment we consider it as a measurable living organism. It is through respirometric technology that we are able to communicate with microbial communities in real time.

Respirometry is a science that is used in determining the rates of degradation of any organic or biological material that releases quantifiable gasses.

Biological Applications

Respirometry is a scientific method of communication with microbial communities, a technology that monitors and measures the respiration of microorganisms. Media for the microorganism can vary in range from ground water or soil to a sewage treatment system or a composting system to almost anything that contains or could contain living organisms. The respirometer can monitor microbes in all of those types of environments and many others. Changes in contaminant concentrations are directly related to changes in respiration during respirometric monitoring and the basis of respirometric results.

In aerobic testing, in most respirometers the measurement is actually a detection and quantification of the off gasses, demand gases or respiration byproducts. In some respirometers it is the change in pressure caused by the consumption of oxygen. Most are equipped with data collection and processing by computer. Most also share a common gaseous scrubbing system to remove CO2 from the reaction chamber, as that would over time poison the microbes. Respirometers are also used for anaerobic testing. RespirTek™ is fully equipped to perform both aerobic and anaerobic work projects.

Chemical Applications

In appropriate chemical matrices, the oxidative degradation process can be monitored. Of value to the interested party in chemical processes is the determination of degradation rate. That information is useful in determining process time and product life cycles, kinetic data and comparison modeling.
