Benefits Of Solid Phase Extraction
The process of pretreatment for what project is suitable for using SPE solid-phase extraction, which is, SPE solid-phase extraction is superior to conventional solvent extraction. These are all common situations.
1. Treatment of organics in water through solid phase extraction
It is basically shaking extraction by using an organic solvent that is water-immiscible. Pesticide residue of SPE solid phase extraction are: SPE solid phase extraction are
It is possible to repeat the pretreatment process indefinitely.
Solvent oscillation may be used to control time , but not frequency, intensity or action. The actions of each person's oscillation differ, making it hard to guarantee a consistent process for everyone. Therefore, the action of solution extraction isn't quantifiable and can not be repeated. In the application of SPE solid phase extraction it's more easy to maintain the uniformity and stability of the column and elution speed. The process of extraction using solid phases can be repeated and measured.
Processing on-site
The analysis of organic matter in water is an ongoing bottleneck. Organic matter can be fairly stable in ponds, reservoirs and in other areas However, once it enters the tiny environment of the sampling bottle, it's likely to change dramatically. Therefore, many organic matter analysis techniques of water require immediate analysis that should not last more than four hours maximum. The average time it takes to bring the water back to the laboratory after removing the sample is around 4 hours. This means that the sample is altered and could impact the validity of the results.
If you choose to use the SPE solid phase extraction technology is implemented, due to its simple equipment, small size and simple portability, it's feasible to conduct pretreatment when taking samples on the spot. The sampler returned to the lab a solid-phase extraction cartridge, not a water sample. This ensures that we are dealing with truely stable water samples in terms of composition. Practically, it is still an enormous task to replace the old method of liquid-liquid extraction with solid-phase extraction technology to detect water. At present, it cannot be replaced completely, however its potential for development is worthwhile to be looking forward to.
Reduction in the use of organic reagents
In the process of processing water samples in the case of solid-phase extraction it is only organic solvents that need to be used for the process that is over ten times less than traditional extraction using liquids. It has positive significance to protect the personal as well as the protection of the environment for the person conducting the experiment.
Solid-phase extraction from bulk biomaterials of pharmaceutical ingredients
This is a great illustration of SPE that can be used in practical applications. It is mostly used for the treatment of urine and blood samples at hospitals. Because the adsorption of components of drugs is the main benefit of SPE solid-phase extraction when combined with a single sample, the composition of the sample is fixed, well suited for large-scale batch purification processes once the procedure is established.
3. Immunoaffinity solid phase extraction
The ideal condition for extraction is specific enrichment or specific exclusion. However, whether it is solid-phase extraction or solution extraction it is essentially the same and compatible, and at the most, it is able to extract at a "certain type" level, but not reach "a certain type of extraction". A degree of extraction. The column for solid-phase extraction can be used for the immunoaffinity technique. It is also utilized to achieve a similar result to theoretical extraction. Practically, the problem is that the concept is not widely known and there are few applications due to the technical difficulty.
