INTRODUCTION
Congratulations on the purchase of your new F-900 Portable Ethylene Gas Analyzer. The F-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 0.01 ppm (10 ppb) in air.
Ethylene production is known to increase in response to plant stress and during 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 F-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 F-900 analyzes the concentration of ethylene in a gas sample for the purpose of research or
ethylene management. The F-900 employs an electro-chemical sensor as well as several other
sensors for temperature, humidity, GPS location, and optionally CO
2
(high and low range), O
2
, and
extended ranges of ethylene. 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 F-900 Portable Ethylene Gas Analyzer.
