Packaged in a foil pouch that is split in two, each FUELSTAT® Test Kit contains a 3 in 1 test paddle and pipette (chemical dropper) in one section and a sample preparation bottle (a sealed 160ml plastic bottle containing 3.0ml of blue extraction buffer), a “dropper cap” and instructions for use in the other section.
The test paddle utilises lateral flow technology (wicking) and antibodies to detect the three groups of micobial contaminants found to grow in middle distilate fuels – Aviation Kerosene, Diesel and Biodiesel.
Test Kit Laid Out FUELSTAT Test Paddle
The test paddle has six (6) Lateral Flow Devices (LFD’s) included in each 3n1 test:
Level 1 (LOW) 3 devices with cut off levels for H.res, bacteria and other fungi at a level derived from IATA Guidance Material where the microbes have established themselves as a consortium and a fuel treatment is required. At this level the consortium is generally undetectable to the human eye.
Level 2 (HIGH) 3 devices with cut off levels for H.res, bacteria and other fungi at a level derived from IATA Guidance Material where the microbes are growing so rapidly, or have been growing for a long time, that they may be causing damage to the structure of the tank or are likely to cause filter blockage and component failure. This level of contamination requires tank cleaning and fuel treatment before it causes further damage. At this level biomass should be very visable in the filtration/water seperation system or on the bottom of the tank.
– Negative (green light) – negligible contamination
Fuel – Below 4,000 cfu/l or 150 μg/l
Water – Below 1,000 cfu/ml or 33 μg/ml
– Low Positive (amber light) – moderate contamination
Fuel – 4,000 – 20,000 cfu/l or 150 – 750 μg/l
Water – 1,000 – 10,000 cfu/ml or 33 – 166 μg/ml
– High Positive (red light) – heavy contamination
Fuel – Above 20,000 cfu/l or 750 μg/l
Water – Above 10,000 cfu/ml or 166 μg/m
