SPE Cartridges

Solid Phase Extraction (SPE) is a sample pretreatment technique that has been developed since the mid-1970s and has become increasingly popular and widely used. Depending on the different adsorbent fillers and adsorption mechanisms, it is mainly divided into normal phase, reversed phase, ion exchange, and mixed-mode solid phase extraction columns.

Normal phase and reversed-phase solid phase extraction columns are mainly used to extract and separate polar and non-polar compounds, but the extraction recovery rates for some charged substances (ionic compounds) are not high.

Ion exchange solid phase extraction is suitable for compounds that can ionize into charged ions. Its mechanism relies on the electrostatic attraction between the charged ions of the target compound and the adsorbent with opposite charges. The sample matrix can be polar, such as aqueous solutions, or non-polar organic solutions, but in practical applications, aqueous solutions are more common, including biological fluids, natural waters such as rivers, lakes, and seas, wastewater, etc.

QuEChERS

QuEChERS is a type of sample pre-treatment method. Due to its advantages of being quick, easy, cheap, effective, rugged, and safe, this method is abbreviated as ‘QuEChERS’.

Compared to methods such as liquid-liquid extraction and solid-phase extraction, the QuEChERS method has the following advantages: first, it is highly efficient, with a simple operation that can process around 20 samples in approximately 40 minutes, greatly improving the sample pre-treatment speed. Second, it is cost-effective, with the processing of one sample costing only about 7 yuan. Third, it is environmentally friendly. The reagents used have low toxicity and require minimal amounts; most operations are conducted in closed centrifuge tubes, reducing the need for frequent opening and minimizing harm to personnel. However, this method also has disadvantages such as poor purification efficiency, susceptibility to matrix interference, and a limited number of available methods for detecting complex sample components such as veterinary drug residues.
