Economic development has brought convenient and comfortable life, but also brought more and more serious pollution. Oil is one of the projects that implement the total emission control of pollutants up to standard in China, and the determination of oil substances in water is particularly important. Infrared oil measuring instrument has small equipment and large application, which is very important in the determination of oil content.



It is well known that oil and water are incompatible. Because the density of oil is lower than that of water, oil will float on the water surface and affect the exchange of oxygen in the water body. Microorganisms in water need to consume oxygen when decomposing oil in water, which leads to poor water quality. We need to take a series of measures to avoid oil pollution.



At present, the main methods for determining oil content in water are:

(1) UV spectrophotometry: simple operation, high sensitivity and precision, but it is difficult to obtain standard oil, resulting in poor data comparability;

(2) Gravimetric method: it is not limited by the type of oil products, but the operation is complex, the sensitivity is low, the determination results are difficult to compare, and the organic substances of non oil and oil substances are difficult to distinguish;

(3) Fluorescence method: Taking mineral oil as the determination object, it has high sensitivity. However, if the number of aromatics in oil components is different, the fluorescence intensity will be very different;

(4) Non dispersive infrared oil: the determination results are highly comparable. When determining mineral oil, it is necessary to eliminate the interference of other non hydrocarbon organics.

Compared with the above methods, infrared spectrophotometry is not limited by the composition and structure of oil products, and the measurement results are more accurate. It is a national standard method in line with international standards.
