About FUELSTAT® resinae PLUS

The Fuelstat® resinae PLUS test utilises lateral flow technology and highly specific antibodies to Hormoconis resinae (H. res.), aerobic bacteria and other fungi that grow in fuel.

The gold labelled antibody is immobilised in the release pad under the 6 sample wells. The fuel/water sample containing an unknown amount of H.res, bacteria and other fungi is added to the sample well and this re-hydrates, allowing the reagents to flow up (wicking) the membrane towards the absorbent pad. Any large particles in the sample, which may block the reaction, are blocked by the filtering action of the pad. During the wicking the H.res, bacteria and other fungi in the sample will bind to the specific antibodies.

As the liquid reaches the test line (T) any free gold-labelled antibodies will bind to the test line. This means if more contamination in the sample than the threshold engineered, there will be no antibodies to bind to the test line, no red line will appear, and this is a POSITIVE result.

If the amount of contamination in the sample is lower than the threshold, there will be free antibodies to bind to the Test Line, a red line will appear, and this is a NEGATIVE result. The quantities of materials immobilised in the device are engineered to provide results at the different thresholds of H.res, bacteria and other fungi in each of the test devices on the test paddle. There is an inbuilt control in the test and for all samples run a line should appear against the C (Control) point in the viewing window. If no Control line appears the test has failed and should be repeated. Recommended by IATA, the FUELSTAT® resinae PLUS test kit, measures the amount of active growth of H.res, aerobic bacteria and other fungi in the sample and provides action and alert levels.
