Product Overview:
The MP 9100 portable UV spectrophotometer uses UV detection technology and is a reliable high-precision water oil analyzer that uses n-hexane instead of carbon tetrachloride, which is harmful to human health and pollutes the environment, as an extractant. Adopting a portable design concept, combined with a guided operation menu, test results can be obtained in just a few minutes, making it very convenient for outdoor use.
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：
? Extraction agents have 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;
? Smaller, lighter, and more portable
The weight of the entire oil measuring instrument is less than 1kg, making it more convenient to carry;
? 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;
? Eliminate interference and have a wide measurement range
High measurement accuracy, wide measurement range, and simple detection method;
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.
? Quick detection and analysis
Fast analysis speed, with a detection time of up to 1 minute, suitable for on-site testing.
? 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
