Ethylene Analyser

EASI - 1
Ethylene Atmosphere Sampling Instrument

Product overview

The EASI-1 analyzer 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 a proprietary nanoporous gold sensor technology, licensed from Fluid Analytics in USA, that offers extraordinary sensitivity to ethylene, at levels as low as 10 ppb in the air. Ethylene is a plant hormone produced by trees, plants, fruits, and vegetables, in response to stress, and during ripening and maturity. Measurements of ethylene gas present in the air have been used as an agricultural diagnostic tool for many decades. However, in the past, sensitive ethylene measurements were available only to expert users: primarily laboratory researchers and scientific equipment technicians. EASI-1 has been designed for growers, storage facility owners and operators, and researchers alike, to increase the value of their products and services.

Potential applications

• Postharvest CA storage room monitoring (Kiwifruit, Apple, Pear, Avocado, Melon, Banana, Passion Fruit, etc.)
• Refrigerated shipping containers monitoring
• Fruit ripening room ethylene control
• Single fruit ripeness indicator
• General gas sensing

Performance

Continuous sampling from a jar containing a single apple, pear or avocado is possible for measurement of the rate of production of ethylene (breathing rate). It is important to know the ethylene production rate of fruit prior to and during CA storage. For example, late harvest apples may produce too much ethylene ( e.g. ≥1 μl kg–1 h–1 in CA conditions) to allow long term storability. EASI-1 provides the accuracy, a real time response necessary to provide these measurements in CA room , in fields or in a laboratory*.

The analyzer provides extremely linear responses at low ethylene concentrations of below 10 ppm. This linearity is critical for simple calibration and measurement over a wide range of concentrations.
