Atomfair IR-Oil 750 Fully Automatic Infrared Oil Analyzer
Product Overview
Atomfair IR-Oil 750 is a professional instrument engineered for measuring oil, petroleum hydrocarbons, and animal/vegetable oils in water, adhering to international detection standards. It boasts stable performance, high measurement accuracy, and rapid detection speed, widely applicable to laboratories, third-party testing institutions, research institutes, and sewage treatment plants in petroleum, petrochemical, smelting, environmental protection, hydrology, and water conservancy industries, delivering efficient and reliable solutions for water quality oil content testing.
Working Principle
Based on the principle of “like dissolves like”, oil substances in water are extracted into tetrachloroethylene, and oil measurement is achieved after oil-water separation. After oil substances pass through a magnesium silicate adsorption column, petroleum hydrocarbon measurement can be completed. Oil substances exhibit absorption characteristics at wave numbers of 2930cm⁻¹ (stretching vibration of C-H bonds in CH₂ groups), 2960cm⁻¹ (stretching vibration of C-H bonds in CH₃ groups), and 3030cm⁻¹ (stretching vibration of C-H bonds in aromatic hydrocarbons). The instrument utilizes the absorption and conversion of spectral energy to conduct qualitative and quantitative analysis of oil substances.
Core Advantages

Fully automated workflow: Automatically completes tetrachloroethylene purity inspection, extractant addition, liquid-liquid extraction, oil-water separation, animal/vegetable oil separation, oil measurement, pipeline cleaning, and reagent recovery without excessive manual intervention.
Multi-parameter simultaneous measurement: Supports simultaneous or separate measurement of total oil, petroleum hydrocarbons, and animal/vegetable oils using a three-wave number correction coefficient method, eliminating the need for additional standard curve drawing.
Flexible sample handling: Freely set 1-N sample positions for discontinuous measurement; dedicated sampling bottles allow direct volume reading, enabling direct on-machine extraction without secondary sample transfer.
Rapid analysis: The entire detection process takes only ~10 minutes with an extraction efficiency > 98%, significantly improving testing efficiency.
Adaptability to complex water quality: Suitable for high-impurity water samples without manual pretreatment or filtration; automatically dilutes high-concentration samples exceeding the threshold to ensure measurement accuracy.
User-Friendly Operation
Multi-communication connectivity: Supports Bluetooth, WiFi, and wired communication, seamlessly connecting to computers, mobile terminals, and remote data platforms for efficient data transmission and management.
Real-time spectrum display: Full-wave number measurement with real-time spectrum visualization, facilitating comprehensive sample information acquisition for both quantitative and qualitative analysis.
Professional software support: Equipped with proprietary oil testing software (with software copyright), integrating spectrum scanning, analysis, calculation, and storage, featuring simplified, flexible, and visualized operation with urgent sample addition functionality.
Safety & Reliability
Personnel health protection: Special waste gas treatment channel prevents staff exposure to tetrachloroethylene, eliminating the need for fume hood use.
Classified waste liquid treatment: Automatically stores extractants and water samples in separate waste liquid bottles, reducing waste treatment volume and environmental pressure.

“The IR-Oil 750” performs automated oil-in-water analysis using tetrachloroethylene extraction followed by infrared spectrometric measurement. Safe operation requires containing tetrachloroethylene vapors within the analyzer exhaust channel, segregating solvent-containing wastes into dedicated bottles, using magnesium silicate adsorption when petroleum hydrocarbons are reported separately, and maintaining thermal stability around the optical system.

How does the Atomfair IR-Oil 750 ensure accurate measurement of aromatic hydrocarbons in water samples?
The IR-Oil 750 uses a three-wave number correction coefficient method (2930 cm⁻¹, 2960 cm⁻¹, and 3030 cm⁻¹) to simultaneously quantify total oil, petroleum hydrocarbons, and animal/vegetable oils, with an error of <3% for standard samples of different ratios. This approach enables effective detection of benzene and toluene without requiring additional standard curve drawing.
What solvent and waste management features does the IR-Oil 750 support for tetrachloroethylene use?
The instrument automatically performs tetrachloroethylene purity inspection, adds extractant, and recovers reagent. It includes a special waste gas treatment channel that eliminates the need for a fume hood, and classified waste liquid bottles automatically separate extractants from water samples to reduce disposal volume and environmental impact.
How does the IR-Oil 750 handle high-concentration or high-impurity water samples without manual pretreatment?
The IR-Oil 750 automatically dilutes high-concentration samples that exceed the measurement range (0.24–100 mg/L) and is suitable for high-impurity water without manual pretreatment or filtration. It uses membrane separation for oil-water separation and achieves extraction efficiency >95% in approximately 10 minutes.
The Atomfair IR-Oil 750 is a fully automated infrared oil analyzer that uses tetrachloroethylene extraction and three-wave number (2930, 2960, 3030 cm⁻¹) spectral analysis to quantify total oil, petroleum hydrocarbons, and animal/vegetable oils in water. Its cast aluminum base with stress aging and zero-tracking technology supports a detection limit of 0.06 mg/L and a repeatability of 1%, while the integrated waste gas treatment and separate waste liquid storage eliminate the need for a fume hood.
Positive
- Automated multi-parameter oil analysis: The instrument automatically performs tetrachloroethylene purity inspection, extraction, oil-water separation, measurement, and pipeline cleaning, and can measure total oil, petroleum hydrocarbons, and animal/vegetable oils simultaneously or separately using a three-wave number correction method without additional standard curves.
- High accuracy and stability: The cast aluminum base with natural stress aging provides optical stability with mechanical positioning error < 1 cm⁻¹, and the zero-tracking technology minimizes the impact of mechanical errors and temperature drift, achieving a detection limit of 0.06 mg/L and repeatability of 1%.
Trade-offs
- Requires dedicated solvent and waste handling: The analyzer relies on tetrachloroethylene as the extraction solvent, which requires careful handling and disposal. Although the instrument includes a waste gas treatment channel and separate waste liquid bottles, the solvent is a hazardous material that must be managed according to laboratory safety protocols.
- Large footprint and infrastructure needs: The system consists of a pretreatment device (530×450×722 mm, 25 kg) and a main unit (540×310×200 mm, 14 kg), requiring substantial bench space and a stable, level surface. The 750 mL maximum water sample volume and 7/11 sample positions may limit throughput for high-volume testing labs.
