Science Made Easy With Solid Phase Extraction System

By Christine Evans


As the world is getting crowded, the number of diseases has increased due to the rise of newly discovered viruses. The crowdedness of the world has forced manufacturers to use artificial materials and or chemicals to speed up production of goods. With the chemicals being carelessly disposed after usage, combined with the existing natural viruses, diseases have become resilient to science. However, scientists have made advancement in their methods, too, through the invention of a solid phase extraction system or SPE system device.

The isolation of compounds from contaminated liquid source is a tool for scientists to impede the formulation and reformulation of viral infections. This invention has been allowing doctors to sort out each particle physically and chemically. This would lead to data extraction, preserving data and its storage, collecting samples from the field, and biological footprint indicators.

An SPE device is a convenience for scientist due to its capability of being portable. Samples that easily degrade can be taken on the site of interest. The device also brings the scientist confidence that its storage is reliable in preserving said samples. This convenience has greatly helped doctors to gather samples from areas where medical facilities are scarce.

Devices offering this system have different kinds. Doctors are able to determine which type is appropriate for their study by the volume of samples, the level of contamination, sample matrix complexity, quality of composite of interest, and type and the strength of the solvent of the matrix. Yet, there are only three ways that a doctor can isolate the composite of interest from any impurity while using a certain type of this device. Mentioned below are the three methodologies.

The selective extraction method. Using an SPE sorbent that would bind the selected compounds of the sample, the compounds are retained when it passes through the tube. One can either choose to collect the adsorbed compounds or discard the tube containing extracted impurities.

Selective washing methodology. The composite and impurities retention are being stored on the packing when a sample passes through. Washing happens when the impurities are rinsed with solutions that are strong enough to remove them, and weak enough to leave the composites behind.

Selective elution methodology. With the usage of another sorbent, the adsorbed composite is to undergo elution. The strong retention of impurities will have such impurities left behind.

This system is also advantageous to the police. This device is capable of the extraction of DNA from evidence that will later on indict the criminal. Each person has a unique biological footprint that the police can easily compare among the suspected criminals.

The world being crowded has contributed to the rising of new diseases that are artificially formed, and the invigoration of existing diseases that were naturally formed. However, this has also contributed in the drive of scientists to invent scientific solutions to these problems. The common people can also contribute to counter the birth and rebirth of new diseases. People can boycott of products from manufacturers that uses harmful products for production.
