OIL680Portable UV spectrophotometer for oil analysis

1. Product Introduction

Adopting an integrated design approach, the instrument is compact, easy to carry, and convenient for on-site use, while complying with the national environmental protection standard HJ970-2018 of the People's Republic of ChinaDetermination of Water Quality and Petroleum by UV spectrophotometry (Trial).

2. Technical principles

According to HJ970-2018Based on the "Determination of Petroleum in Water Quality by UV spectrophotometry" (Trial), a quantitative amount of n-hexane is injected into the water sample, and oil substances in the water are extracted by magnetic stirring. The extraction solution is dehydrated and magnesium silicate adsorbed to remove polar substances such as animal and vegetable oils225nmThe absorbance was measured at the wavelength, and the petroleum content and absorbance values followed the Lambert Beer law.

3. application area

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

4. Instrument characteristics
