Oil analysers are critical instruments used to detect and quantify oil content in water, ensuring compliance with environmental regulations. The ERUN-ST3-J4, detailed in the attached product datasheet, uses UV spectrophotometry to measure oil levels accurately. This is vital for industries like environmental monitoring, transportation, and research, where oil pollution can harm ecosystems and human health.
With growing concerns about water pollution, these devices help meet national standards such as HJ970-2018, offering a safer alternative to banned carbon tetrachloride with n-hexane extraction. Their versatility makes them indispensable for maintaining clean water supplies.
The ERUN-ST3-J4 operates by extracting oil from water samples at a pH ≤ 2 using n-hexane, followed by dehydration with anhydrous sodium sulfate. After removing polar substances with magnesium silicate, it measures absorbance at 225nm, adhering to the Lambert-Beer law. This method ensures high sensitivity, with a detection limit of 0.01 mg/L when using a 500ml sample and 25ml extract in a 2cm quartz cuvette.
This precision eliminates interference from polar oils, making it reliable for diverse applications. The device’s ability to scan 190-1100nm and offer multi-functional testing enhances its utility beyond oil detection.
Long-life light source with automatic wavelength correction.
High sensitivity with a detection limit of 0.01 mg/L.
Versatility as both an oil analyser and UV-Vis spectrophotometer.
Compliance with HJ970-2018, GB5749-2006, and other standards.
