A solid-phase extraction procedure for DNA purification

SUMMARY AND CONCLUSIONS Solid-phase extraction materials which can directly replace phenol in the classical liquid/liquid extraction procedure for DNA purification have been developed. The solid-phase extraction materials have surface characteristics chemically similar to those of phenol and presumably interact with proteins in an analogous manner.

Environmental and food analysis usually require the use of sample preparation steps, with significant utilization of solid-phase extraction techniques. This review article covers recent trends in the use of metal–organic frameworks (MOFs) as novel sorbents, with particular emphasize on miniaturized methods to follow green analytical chemistry principles. Thus, the use of MOFs in miniaturized

The Concept and Basic Principles of Solid Phase Extraction The Concept of Solid Phase Extraction. Solid Phase Extraction Cartridges (SPE column, or Solid Phase Extraction Cartridges, or SPE cartridges for short) is a sample pretreatment method based on chromatographic separation. It is a sample preparation technology developed in the mid-1980s.

Essentially, the procedure originated by Tswett is now referred to as solid-phase extraction (SPE) which was commercially introduced in the mid-1970s [13], [14]. SPE remains one of the most widely-used sample preparation procedures today for processing liquid (mainly aqueous) matrices.

Solid phase extraction (Conte et al., 1996) is rapid, inexpensive and can detect concentrations at the parts per billion level. A third alternative is solid phase micro-extraction (SPME), a method pioneered by Pawliszyn and colleagues (Belardi and Pawliszyn, 1989).

Solid-Phase Extraction (SPE) is a sample preparation method that is practised on numerous application fields due to its many advantages compared to other traditional methods. SPE was invented as an alternative to liquid/liquid extraction and eliminated multiple disadvantages, such as usage of large …

Abstract Sample pretreatment is one of the most crucial and error-prone steps of an analytical procedure; it consents to improve selectivity and sensitivity by sample clean-up and pre-concentration. Nowadays, the arousing interest in greener and sustainable analytical chemistry has increased the development of microextraction techniques as alternative sample preparation procedures. In this

  • What is solid phase extraction (SPE)?
  • Solid phase extraction1 (SPE) is a sample preparation technique using a solid adsorbent contained most commonly in a cartridge device (Figure 1), or on a disk to adsorb select species from solution. SPE is used to isolate a species in a sample or to clean-up a sample before analysis. Figure 1. Photograph of an SPE cartridge (top).‌
  • What are the applications of solid-phase extraction (SPE) in chemistry?
  • Furthermore, the applications of these techniques are discussed in detail along with their advantages in analyzing pharmaceuticals, biological samples, natural compounds, pesticides, and environmental pollutants, as well as foods and beverages. Solid-phase extraction (SPE) is an effective way to prepare samples in chemistry.‌
  • What is solid phase extraction in chromatography?
  • Solid phase extraction (SPE) was developed from classical chromatography in which an adsorbing medium is used to separate analytes according to their differing equilibrium affinities for the sorbing medium. This technique is also called liquid-solid extraction. What is solid phase extraction?‌
  • How long does a solid phase extraction procedure take?
  • The overall procedure lasted 15 min and the calculated enrichment factors were 10, 30, and 80 for 2 mg, 5 mg, and 10 mg sorbent, respectively . Solid phase extraction techniques advantage other sample pretreatments in terms of ease of operation, mainly as consequence of its possibility to be incorporated within automated schemes of analysis.‌
  • What is solid phase extraction & concentration?
  • Solid-Phase Extraction is a useful technique for isolation and separation applications. But also, con-centration is one of the goals in its application fi eld. The analyte leaves the pretreated column or cartridge which fi lled with required sorbent in a small volume of solvent.‌
  • How does solid phase extraction work?
  • By having two different functional group sorbents present within one cartridge. Solid phase extraction normally involves bringing an aqueous sample into contact with a solid phase or sorbent, whereby the compound is selectively adsorbed onto the surface of the solid phase. The solid phase sorbent is usually packed into small tubes or cartridges.
