FIELD: engines.
SUBSTANCE: invention relates to quality control of fuel for jet engines by means of optical devices, in particular to determination of amount of additives "Hitech-580" and "Agidol-1", and can be applied in analytical laboratories, petroleum enterprise laboratories. Method involves collecting sample, spectrophotometry with measurement of optical density at certain wavelengths, refractometry, and calculating concentration of additives in fuel by mathematical relationship, wherein preliminary multiple concentration of fuel sample is performed before spectrophotometry, and extraction of additives with ethyl alcohol is performed before refractometry.
EFFECT: invention provides extending range of methods for determining additives in fuels for jet engines, applying IR-spectroscopy without reduced accuracy requirements.
