Overview

OIL 820 UV spectrophotometer oil analyzer

Product Details

1. Compliant with national standards

National Environmental Protection Standards of the People's Republic of China“HJ970-2018”Water quality Determination of petroleum products UV spectrophotometry (trial)

2. Using reagents:

hexane

3. Technical principles

existpH≤2Under certain conditions, the oil substances in the sample were extracted with n-hexane. The extract was dehydrated with anhydrous sodium sulfate and then adsorbed with magnesium silicate to remove polar substances such as animal and plant oils225nmMeasure absorbance at wavelength, petroleum content and absorbanceThe value conforms to Lambert Beer's law.

4. application area

Used for the determination of petroleum in surface water, groundwater, and seawater
