Mingqin FMP 9100 UV spectrophotometer is a high-precision UV spectrophotometer commonly used in laboratories to measure petroleum in surface water, groundwater, and seawater. It uses n-hexane extractant instead of infrared method carbon tetrachloride extractant and meets the requirements of HJ 970-2018 Water Quality Determination of Petroleum by UV spectrophotometry. The instrument is easy to operate and can be used for routine testing in the laboratory, as well as for daily testing and measurement at fixed stations. The measurement is fast, and combined with a guided operation menu, test results can be obtained in just a few minutes. Its application prospects are very broad.
Standard: HJ970-2018 Determination of Petroleum in Water Quality by UV spectrophotometry Instrument principle: UV spectrophotometry: Under the condition of pH ≤ 2, oil substances in the sample are extracted with n-hexane. The extract is dehydrated with anhydrous sodium sulfate and then adsorbed with magnesium silicate to remove polar substances such as animal and vegetable oils. The absorbance is measured at a wavelength of 225nm, and the content of petroleum is proportional to the absorbance value, which conforms to Lambert Beer's law. Product features: 1. The extractant has lower toxicity In response to policy requirements, n-hexane is used as the extractant to replace the highly toxic carbon tetrachloride, and it is easy to obtain; 2. Smaller, lighter, and more portable The weight of the entire oil measuring instrument is less than 1kg, making it more convenient to carry; 3. Long battery life and portability Built in large capacity battery, providing continuous power for at least 8 hours; comes with a charger for quick charging; 4. Eliminate interference and have a wide measurement range High measurement accuracy, wide measurement range, and simple detection method; 5. After adsorption treatment with magnesium silicate, the interference of polar materials can be eliminated in the extraction solution; During the experiment, the light source was fixed, without any offset, and the wavelength remained stable at 225nm Unique portable workbench design with stable performance. 6. Rapid detection and analysis Fast analysis speed, with a detection time of up to 1 minute, suitable for on-site testing. 7. Complete supporting equipment Accessories include PMP 9100 host, testing reagent kit, pipette kit, separating funnel, operation manual, portable host case, charging plug and data cable, etc Application areas: 1. Emergency monitoring - oil spills, pipeline leaks, tanker accidents, and other oil spills 2. Routine testing - various water bodies such as surface water, groundwater, domestic water, and industrial wastewater 3. Wastewater Monitoring - Petroleum Content in Smelting Industry Wastewater, Oilfield Produced Water, and Refinery Wastewater 4. Aquaculture water quality testing - Marine fishery water quality testing 5. Specific scenario monitoring - monitoring of external drainage from petroleum and petrochemical, offshore oil extraction 6. Environmental monitoring - environmental monitoring of agriculture and forestry, hydrology and water conservancy, railways, and thermal power plants
