AE01/AE03 automatic extractor extraction bottleTechnical Principle
When determining oil according to the "GB/T16488-1996 Water Quality - Determination of Petroleum and Animal and Vegetable Oils - Infrared photometric method", it is necessary to extract the water sample. Connect extraction bottles A and B with a U-shaped tube. Due to the higher specific gravity of the extraction solvent than water, it will be relatively fixed in the position of the U-shaped tube under the action of gravity. When the vacuum pump extracts air from one end of extraction bottle A, the water sample will quickly pass through the extraction solvent from extraction bottle B and enter extraction bottle A. Conversely, when the vacuum pump extracts air from one end of extraction bottle B, the water sample will quickly pass through the extraction solvent from extraction bottle A and enter extraction bottle B. By controlling the total extraction time and switching the extraction time with a time relay, oil substances can be extracted from water.

Comparison with traditional extraction methods
indicator |
Automatic extractor |
Manual extraction using a separating funnel |
safety |
The operator does not directly come into contact with silicon chlorine and carbon, and the extraction process is fully enclosed. The exhaust pipe can be directly connected to the window or ventilated kitchen, ensuring high safety. |
The operator needs to open the piston exhaust of the separating funnel during the operation of the project, which results in poor safety when the human body comes into contact with silicon chloride. |
extraction efficiency |
The extraction solvent passes through the water sample every time and comes into full contact with it, resulting in high extraction efficiency. |
The relative extraction efficiency is low. |
repetitiveness |
After setting the conditions, there is no need for manual intervention, pure mechanical operation, and good repeatability. |
The artificial influence is significant, the conditions are not constant, and the repeatability is poor. |
labor intensity |
Fully automated operation and the ability to extract multiple samples simultaneously, with low labor intensity. |
When the volume of water sample to be extracted is large or there are many samples, the labor intensity is high. |
