Overview

The laboratory desktop UV spectrophotometer is a professional equipment used for precise detection of oil concentration in water. Taking the ERUN-ST3-J4 laboratory bench UV spectrophotometer developed and produced by Yingrun Group as an example, it is a high-precision instrument designed according to the requirements of national environmental monitoring technical specifications, specifically used to detect the content of petroleum in surface water, groundwater, seawater and other water bodies. It plays an important role in laboratories such as environmental testing, railway environmental testing, automobile manufacturing, transportation environmental testing, and environmental research.

With the deepening implementation of the Water Pollution Prevention and Control Law and the Outline of the Ecological Environment Monitoring Plan (2021-2035), the supervision of petroleum pollutants in water bodies is becoming increasingly strict. The traditional infrared oil detection method relies on tetrachloromethane, an ozone depleting substance that has been banned by the Montreal Protocol. In 2018, the National Ecological Environment issued HJ970-2018 "Determination of Water Quality and Petroleum by UV spectrophotometry", which clearly recommended the use of n-hexane instead of tetrachloromethane and stipulated that the absorbance should be measured at 225nm wavelength after extraction under pH ≤ 2 conditions. The laboratory desktop UV spectrophotometer is the core equipment designed to implement this new national standard.

The ERUN-ST3-J4 laboratory bench top UV spectrophotometer developed and produced by Yingrun Group meets the national standard "HJ 970-2018 Determination of Petroleum in Water Quality - UV spectrophotometry", using n-hexane extraction and 225 nm UV absorption measurement to achieve highly sensitive, accurate, and fast detection of petroleum concentration in water samples. It is an ideal equipment for environmental monitoring and scientific research institutions.

Product features of laboratory desktop UV spectrophotometer oil analyzer:

★High stability and precision

Using a long-life deuterium lamp as the light source, coupled with high-performance gratings and imported photomultiplier tube detectors, the instrument ensures good stability and repeatability, with a relative standard deviation (RSD) of better than 2%.

★Automation and Intelligence

Built in automatic extraction, oscillation, and separation modules achieve full process automation from sample processing to measurement and analysis. Equipped with a large-sized color touch screen, the operation process is graphically guided, greatly reducing human operation errors.

★Powerful data management

The instrument can store over 10000 sets of detection data and calibration curves, and supports USB export or direct connection to LIMS laboratory information management system, achieving paperless traceability and efficient management of data.
