The use of superficial fluid extraction systems is one of the best extraction techniques. These systems use supercritical carbon dioxide as the solvent for the process. This solvent has two key benefits. In the absence of oxygen and at low temperatures, it has the best penetration matrix and low viscosity. Therefore, if one is extracting heat sensitive and oxidized products, the system guarantees the best results. More to this, the process is relatively fast and requires no organic solvents. This is contrary to other extraction methods. That said, here are a few aspects to know about superficial fluid extraction systems (SFE).
Configuration of SFE systems
The main components of a superficial fluid extraction system include an automatic back pressure 
regulator valve and supercritical carbon dioxide pump. Besides, the system comprises of a co-solvent pump. If you are looking for supercritical co2 extractor for sale, be prepared to examine their unique properties before buying one. Ideally, the sample to be extracted determines the size of the system. More to this, during the extraction process, certain parameters must be present. These parameters include pressure, temperature, solvent and co-solvent. The ratios of these constraints are adjusted to suit the sample being processed.
SFE for analyzing residual pesticides in food and soil
This system is also a perfect solution for analyzing residual pesticides components both in soil and food samples. However, this process is versatile since supercritical carbon dioxide is used during the extraction process.
Key features of a residual extraction system
Some of the features that make this system the best include simplicity in operation, quick extraction, and environmentally friendly. In addition, it is cheap, no trace pesticides are available, and blockages and contaminants are reduced significantly.
Flexibility of the system
The extraction process uses either 10 ml or 50 m. A 10 ml container is ideal when one is analyzing the functionality of the process. On the other hand, 50 ml container is ideal if one is interested in the sample volume and requires sensitivity analysis. One of the benefits of the 50 ml container is that it is efficient.
Applications of SFE systems
This extraction procedure is ideally suited for extraction of active ingredients. Also, it is possible to extract medicinal constituents, flavors natural products, pharmaceuticals and fat-soluble vitamins. Also, SFE system can be used to eliminate unwanted products in the extraction of various substances. Finally, this system can act as a precursor to the processing of samples before they are separated using various chemicals.
