Introduction
Congratulations on the purchase of your new CI-900 Portable Ethylene Gas Analyzer. The CI-900
provides accurate real-time measurement of ethylene gas concentrations in a compact instrument
suitable for field and laboratory use. At the core of the instrument is an electrochemical sensor that
offers extraordinary sensitivity to ethylene, at levels as low as 0.04 ppm (40 ppb) in air.
Ethylene production is known to increase in response to plant stress and during fruit ripening and
maturity, and until recently, sensitive ethylene measurements were available only through
elaborate and expensive gas sampling and gas chromatography analysis. The intent of the CI-900’s
portable design is to aid the research community in developing real-world ethylene management
applications for the benefit of growers, processors, and consumers.
The CI-900 analyzes the concentration of ethylene in a gas sample for the purpose of research or
ethylene management. The CI-900 employs electro-chemical sensors as well as several other
sensors for temperature, humidity, GPS location, and optionally carbon dioxide (CO
2
: high and low
range) and oxygen (O
2
). During a sample, the subject gas travels across the surface of the electrode
and diffuses into the electrochemical cell where ethylene is oxidized. The current created by the
oxidation is measured and interpreted as the concentration of ethylene (reported in parts per
million or ppm).
We hope you enjoy using your CI-900 Portable Ethylene Gas Analyzer.
