Gas analysis to extend shelf life in sweet potato
Partnering with the Council for Scientific and Industrial Research – Savanna Agricultural Research Institute, Issah Sugri and his team are using the F-900 Portable Ethylene Analyzer to glean crucial insights into important commodities in Ghana. Armed with this data, the team is able to advise farmers and policy makers on low-cost methods to decrease postharvest losses and increase economic prosperity in the region.

Does this product come with a warranty?
-
All devices from Felix Instruments – Applied Food Science come with a 12- month warranty at the point of sale. The warranty covers repairing and replacing defective parts of the instrument that were manufactured directly by Felix Instruments. The warranty does not cover wear and tear, neglect, misuse, accident, or excessive deterioration. Further, unauthorized repair and alteration by an unauthorized party voids the warranty. More information can be found in the operation manual of your instrument.
-
Is the Produce Quality Meter waterproof?
-
The Portable Ethylene Analyzer is not designed to be waterproof and should not be used underwater. The Portable Ethylene Analyzer is designed to be water-resistant. Use in light rain is fine, however, there are electronics inside of the Portable Ethylene Analyzer that can be damaged from water entering the instrument, so it is not recommended to use the Portable Ethylene Analyzer during heavy rainfall.
-
What is the difference between the F-900RK and the F-900?
-
The F-900 is the ethylene analyzer. The F-900RK is an optional accessory kit for the F-900 that includes a 2L chamber, connetion wand, injection port kit for small gas samples, and a hard carrying case.
-
How does the sample reach the analyzer?
-
In Continuous monitoring mode, gas enters through the inlet of the device and is drawn in by the pump. The inlet can be free of tubing, in which case it will measure ambient air, or it can be connected by tubing to a chamber or other measurement location or apparatus. In GC Emulation Mode samples are injected into a special port that connects to both the inlet and outlet of the device
