Both pressure and temperature can be used as parameters to adjust the extraction process. The pressure and temperature can be changed to achieve the purpose of extraction. The process is simple and the extraction speed is fast.
Reflective Concave Blazed Holographic Gratings
China star optics can provide customers with a variety of replicated grating products such as diffraction gratings, reflective gratings,holographic gratings,concave gratings etc. to meet different needs. Maximum ruled area is up to 300x300mm2 for plane ruled diffraction gratings. For replicated diffraction and transmission gratings the ruling density can be from 20 grooves per millimeter to 2400 grooves per millimeter, wavelength from 0.2 micron to 25 microns.
Characteristics of supercritical carbon dioxide fluid extraction and separation:
1. The supercritical carbon dioxide fluid extraction and separation is carried out under the condition of near room temperature and carbon dioxide to prevent oxidation and escape of the heat sensitive substance. Therefore, the extract maintains the active ingredient of the medicinal plant and can have high boiling point and low volatility. And the pyrolyzed material is extracted far below its boiling point.
2. Supercritical carbon dioxide fluid extraction and separation does not use organic solvents, and the extracted material has no residual solvent substances, ensuring pure naturalness.
3. The extraction and separation are combined into one. As the pressure drops or the temperature rises, the carbon dioxide and the extract quickly become two phases and are immediately separated, and the extraction efficiency is high and the energy consumption is less.
4. Carbon dioxide is an inactive gas. It does not react chemically during the extraction process and is a non-combustible gas. It is odorless, odorless, non-toxic and safe.
5, carbon dioxide is cheap, high purity, easy to prepare, can be recycled in production, effectively reducing costs.
6. Pressure and temperature can be parameters for adjusting the extraction process. The pressure and temperature can be changed to achieve the purpose of extraction. The process is simple and the extraction speed is fast.
