The process of pretreatment for what project is appropriate for SPE solid-phase extraction technology. That is, SPE solid-phase extraction is more ideal than ordinary solvent extraction. There are generally the following scenarios.

1. Solid phase extraction is used to remove organic matter in water.

This is essentially shaking extraction with a water-immiscible organic solvent. The benefits of SPE solid phase extraction are: SPE solid phase extraction include:

It is possible to repeat the pretreatment process quantitatively.

The action of oscillation in solvents is usually limited to controlling the duration, but it is not able to determine the frequency or intensity. QuEChERS Kits is also not able to control the action. We are aware that every person’s oscillation actions are different and it’s difficult to ensure that the same action occurs even for the same person. Solution extraction is not repeatable since it’s not quantifiable. With SPE solid phase extraction, it’s more easy to maintain the uniformity and stability of the column and the elution speed. This means that the extraction process of extraction using solid phase can be repeated in a quantitative manner.

On-site processing

There is a long-standing problem in the analysis of organic matter in the water. This is due to the fact that organic matter can be stable in reservoirs, ponds and other settings, however it can change rapidly when it is placed in the small environments of the sample bottles. So, many organic matter analysis techniques of water require immediate analysis which can not exceed 4 hours at most. In general, the time from returning the water to the laboratory is far over 4 hours. the sample has changed, and the reliability of the analysis results is a possibility.

Because of its simplicity its small size and portability, the SPE solid-phase extraction technique can be used to pre-treat samples on-site. The sampler returned to the lab with a solid-phase extraction cartridge, not a water sample. This ensures that we’re dealing with authentically stable water samples. Practically, it is still a lot to be done to replace the traditional extraction of liquids with solid-phase extraction technology to detect water. It cannot be replaced completely currently, but it is something worth paying attention to.

Reduced consumption of organic Reagents

When water samples are processed using the solid phase extraction method, organic solvents should be used for elution. This is over 10 times less than the traditional extraction of liquids. It is beneficial to protect the personal and protection of the environment of the experimenter.

Solid-phase extraction from bulk biomaterials of pharmaceutical ingredients

It is a pretty successful instance of Solid Phase Extraction in real-world applications, specifically for pretreatment of blood and urine samples at hospitals. The benefit of SPE in solid phase solid-phase extract is that the drug components are taken up. This makes it ideal for batch purification operations.

3. Solid phase immunoaffinity extraction

The ideal extraction condition is specific enrichment, or specific exclusion. However regardless of the method of extraction, whether solution or solid phase extraction they’re both almost identical and are compatible. It can only extract at a “certain type” level but not at “a specific kind”. A level of extraction. Based on the column for solid-phase extraction, the immunoaffinity technology can be used, and its biological specific selective adsorption can be used to achieve a perfect extraction close to the theoretical. The problem is that although the concept is great but there aren’t many applications available due to the relatively complicated technical difficulties.
