Detection principle:
Under the condition of pH ≤ 2, the oil substances in the sample are extracted by n-hexane. The extract is dehydrated by anhydrous sodium sulfate and then adsorbed by magnesium silicate to remove polar substances such as animal and plant oils. The absorbance is measured in the ultraviolet region, and the petroleum content and absorbance value conform to Lambert Beer's law, thus quantitatively analyzing the petroleum content in water.
Fully compliant with the new environmental standards, using ultraviolet light for detection, the instrument automatically measures absorbance, and then automatically calculates the final concentration. The operation is simple and the results are accurate
The extraction agent used is n-hexane, which has a much lower impact on humans and the environment than the carbon tetrachloride extraction used in infrared oil detectors
※ Adopting a 10.1-inch high-resolution true color touch screen, the user-friendly and concise menu design makes operation more time-saving. A single interface contains detailed information such as detection time, detection items, absorbance, transmittance, concentration values, wavelength values, curves, etc
※ Measurement items can be selected as automatic or semi-automatic measurement
The instrument has scanning function and can evaluate the purity of blank
※ Built in multiple preset standard curves and supports custom curves
