The UP-A680 series fully automatic infrared oil analyzer is a professional instrument for achieving fully automatic measurement of oil, petroleum, and animal and vegetable oils in water. This instrument is fully developed in accordance with the national standard "HJ637-2018 Water Quality - Determination of Petroleum, Animal and Plant Oils - Infrared Spectrometric Method". It has stable performance, high accuracy, and fast detection speed, and is an essential instrument in the fields of environmental protection, water conservancy, petroleum and petrochemical industries.

The UP-A680 series fully automatic infrared oil analyzer uses the principle of similar solubility to extract oil from water into tetrachloroethylene. After oil-water separation, the oil is measured, and after passing through a magnesium silicate adsorption column, petroleum is measured. Oil substances have absorption at spectral bands with wave numbers of 2930cm-1 (stretching vibration of C-H bond in CH2 group), 2960cm-1 (stretching vibration of C-H bond in CH3 group), and 3030cm-1 (stretching vibration of C-H bond in aromatic hydrocarbons). Qualitative and quantitative analysis is carried out using the absorption and conversion of spectral energy.

HJ637-2018 Water Quality - Determination of Petroleum, Animal and Plant Oils - Infrared Spectrometric Method

Suitable for laboratories, third-party testing institutions, research institutes, sewage treatment plants and other fields in industries such as petroleum and petrochemical, smelting, environmental protection, hydrology and water conservancy.

Tetrachloroethylene testing: Automatically complete the purity testing of tetrachloroethylene, and only after passing the test can sample testing be carried out.

Independent cleaning position: Modular cleaning of inner and outer walls and the entire pipeline, effectively avoiding cross contamination.

Automatic switching of adsorption column: The magnesium silicate adsorption column can be automatically switched once for each sample detected, reducing cross contamination to the lowest possible level.

Accurate detection of aromatic hydrocarbons: Both benzene and toluene can be effectively detected, with a detection error of less than 3% for different ratios of standard samples.

The measurement methods for standard samples and water samples are the same: when measuring standard samples or water samples, all samples are pre treated and sent to the host for measurement, and the results are displayed. To further verify the minimal impact of the preprocessor on the sample extraction results.

Good stability: Adopting a cast aluminum base and undergoing natural stress aging treatment, it has good optical stability.

High accuracy: The instrument has a high degree of automation, reducing human error and improving measurement accuracy and repeatability.

Accurate detection of aromatic hydrocarbons: Both benzene and toluene can be effectively detected, with a detection error of less than 3% for different ratios of standard samples. Make the instrument truly serve the actual water sample.

Moisturizing: Simulate manual testing to lubricate pipelines and colorimetric dishes, improving detection accuracy.

Real time zeroing: Zero tracking technology, precise positioning, error elimination, mechanical error, temperature drift effects approaching zero, mechanical positioning error less than 1 wavenumber.

Fully automatic operation: Automatically completes the testing of tetrachloroethylene, addition of extractants, liquid-liquid extraction, oil-water separation, separation of animal and vegetable oils, oil measurement, pipeline cleaning, automatic recovery of reagents, and other processes.

Simultaneous measurement of three parameters: achieve simultaneous or separate measurement of total oil, petroleum, and animal and vegetable oils. Using the three wavenumber correction coefficient method, there is no need to make a standard curve.

Maintenance management: Applying the concept of lifespan management, the system automatically prompts maintenance information such as pipelines, components, consumables, etc., making it convenient for users to replace them in a timely manner and ensuring stable and reliable operation of the equipment.

Sample grade: freely set 1-N sample grades, can be measured non continuously.

Communication management: coexistence of wireless and wired, achieving seamless connection with computers, mobile terminals, and remote data platforms.

Special sampling bottle: equipped with an oil analyzer dedicated sampling bottle, it can directly read the volume without the need for secondary transfer of the sample, and can be directly extracted on the machine.

Safety and Health: The exhaust gas is adsorbed by an activated carbon adsorption column to prevent workers from coming into contact with tetrachloroethylene, and it can be used without a fume hood.

Remote control: can operate off-site, creating a new mode of detection.

Extraction agent and water sample separation: The instrument can automatically store the extraction agent and water sample in different waste liquid bottles, reducing the amount of waste liquid treatment.

High extraction efficiency: The extraction efficiency is greater than 98% using the air blowing and jet extraction methods.

Suitable for various water qualities: Suitable for high impurity water quality, no need for manual treatment and filtration, can be tested directly on the machine.

Fast analysis speed: The entire process only takes 5-10 minutes.
