It can also be widely applied in industries and departments such as environmental monitoring, oil extraction, oil processing, maritime supervision, port and terminal management, and university research institutes. The detection and analysis methods for petroleum pollutants: infrared method, gravimetric method, gas chromatography method, fluorescence method, infrared method. Due to the toxicity and environmental pollution of fluorocarbons and carbon tetrachloride, they are gradually being phased out. According to the definition of EPA Method 1664 issued by the new US Environmental Protection Agency, petroleum is a n-hexane extract. Principle and basis of fluorescence detection of petroleum: After extracting petroleum substances in water with n-hexane, aromatic hydrocarbons in petroleum can produce fluorescence under UV excitation, and the intensity of fluorescence is linearly related to the content of petroleum. The fluorescence intensity of petroleum substances from different sources is very similar, and a unified standard substance can be used. Although fluorescence spectrophotometry can only detect aromatic hydrocarbons in water, experiments have shown that all petroleum pollutants contain aromatic hydrocarbons, which are also stable components in pollution, accounting for over 90% of the pollutant content. After petroleum pollutants enter water, hydrocarbons below C18 are insoluble in water, and 90% will evaporate within a few hours. Low molecular weight aromatic hydrocarbons dissolve in water, and their concentration gradually increases and remains relatively stable.

Adopting advanced UV fluorescence detection technology

Dual channel: Channel "A" is used to measure condensate oil and refined hydrocarbons, while the new channel "B" is used to measure crude oil, greatly increasing the measurement range (>1000ppm) without the need for sample dilution.

Dual channel design can reduce operational errors and minimize solvent usage.

***Quick analysis program (<4 minutes/sample)

Compatible with all general extraction solvents

Disposable test tube, low price, no need for complicated cleaning, convenient and fast

Solvent-free evaporation
