1、 UV980Fully automatic portable UV oil analyzerPurpose:

Suitable for fully automatic detection and analysis of petroleum in surface water, groundwater, and seawater.

2、 Compliant with standards:

Compliant with the national standard "HJ970-2018 Determination of Petroleum in Water Quality by UV spectrophotometry (Trial)", according to the HJ970-2018 standard, at pH ≤ 2

Under certain conditions, the oil substances in the sample were extracted with n-hexane. The extracted solution was dehydrated with anhydrous sodium sulfate and then adsorbed with magnesium silicate to remove polar substances such as animal and plant oils. The extraction was carried out at 225 nm

The absorbance was measured at the wavelength, and the petroleum content and absorbance values followed Lambert Beer's law.
